Overview of the borehole pump "Aquarius": device, characteristics, connection and operation rules. How to choose and install a submersible pump for a well The principle of operation of a deep pump

If you want to have free water in any quantity on your own site, then you should start by drilling a mine to an aquifer. The second step will be the installation of a downhole pump in the well. It is the proper operation of such equipment that will guarantee high-quality watering of garden plants, the uninterrupted operation of a washing machine and dishwasher, a bathroom and a bathroom.

Deep well pumps have different capacities, sizes and other parameters. In this article, we will look at the main selection criteria. Installing optimal equipment will save you from many problems in the future and will give you confidence in the constant presence of H 2 O in your area.

General provisions

In order to successfully pump water from wells, wells or other bodies of water, there are the following types of pumps:

Self-priming. Such equipment is installed on the surface and sometimes looks like a full-fledged pumping station. They do a good job with sandy wells that have a relatively shallow depth.

Submersible. They have a large power, the volume of pumped liquid and the height of the pressure column. Structurally able to penetrate even very narrow shafts. Ideal for artesian wells.

Selection and installation

Since a deep well pump is the best fit, let's move on to the rules for choosing it. To do this, first of all, it is necessary to determine where the water supply is required and in what quantity.

Right Criteria

pump performance. The amount of liquid it can distill in one hour.

Head height. The force of the push of the liquid is selected in accordance with the depth of the mine and its distance from the house.

Well debit. The actual volume of water that can be provided by an aquifer per hour of continuous supply.

In this regard, you should start choosing pumping equipment after you finish drilling a well and provide a technical passport with all the necessary data.

It should indicate:

Shaft diameter. What will determine the diameter of the submersible apparatus.
Static and dynamic water levels. The first one is formed in case of idle time of the structure, and the second one - in case of its active use.

Well productivity, which is measured by the number of cubic meters of fluid transferred per hour.
Mine depth. Significantly affects the required head height.

You should not purchase an overly powerful submersible pump for two reasons:

Its price will be much higher, but why overpay?
If its productivity is greater than the productivity of the well, then it will not have time to fill with water. Because of this, the operation of a “dry” run will follow, which, in the absence of special protection, will lead to a burnout of the engine.

Thus, we now know that the maximum power should not exceed the amount of water inflow. What affects the minimum?

Let's consider:

Your family size. On average, one adult needs about 1000 liters per day. Multiply this number by the number of permanent residents and you will know your home's daily water requirement.

Availability and area of the garden. Watering crops usually takes up to 2000 liters of the required liquid.

The number of concurrently used consumption points.
Here is an approximate list of them with a standard flow rate, measured in m 3 / hour:
- washing - 0.7;
- bathroom - 1.2;
- bidet - 0.3;
- shower room - 0.8;
- dishwasher - 0.6;
- washstand - 0.3;
- washing machine - 0.8;
- bathroom - 0.4
So, in order to start the washing machine and fill the bath at the same time, you will need equipment with a capacity of at least 2000 m 3 / hour. But, do not forget that there may be a need at this time to wash the dishes and go to the toilet.

In addition to the power that we choose based on the capabilities of the well and the needs of the residents, it is also important to select the correct head height, which will require fluid supply.

We perform calculations as follows:

We take the height of the house and add 6 meters to it.
The resulting amount is multiplied by the coefficient of pressure loss in the process of moving through the pipeline. It is equal to 1.15.
Now add the depth of the mine to the surface of the water surface. We take this value from the technical passport provided by the drilling company.
Next, you should take into account the distance of the well from the building in need of water supply. It is generally accepted that 10 m horizontally equals 1 m vertically.

Suppose that the height of your house is 7 m, the depth of the shaft is 30 m, and the distance from the water intake points is 20 m. Substitute: (7 + 6) * 1.15 + 30 + 2 = 46.95. That is, a pump is required, the head of which is at least 47 m.

The most important is just the calculation of the height of the water supply than the power of the pump. Since it is rare when all points of water consumption are open, but a miscalculation with pressure can lead to a complete absence of H 2 O in the water supply system.

Tip: if there is a possibility of an error in calculating the performance of the equipment, it is recommended to install a membrane tank.
With it, it will be possible to set the pressure level, which will avoid water hammer along with frequent engine starts and stops.

Mounting

How to install a submersible pump in a well? To do this, you will need the apparatus itself, a metal-plastic pipe of the required length, an adapter, a steel cable and an electric cable with waterproofing.

The installation instructions look like this:

We fasten a special nipple to the pump outlet, sealing the connection with the help of "winding". It will serve as an adapter for the casing thread.

Before fixing, we align the polyethylene pipe as much as possible with our own hands. This will allow you to lower the device most evenly.

We connect the power cable. In this case, it is required to ensure waterproofing as best as possible using special corrugations or heat shrink tubing.

Tip: when buying equipment, immediately check the presence of the wire.
Because usually it is not included in the package and therefore it should be purchased separately.

We tie a steel cable to the lugs specially designed for this, located on the pump housing. From above it can be attached to a winch mounted on a tripod. This will facilitate the immersion of the apparatus to great depths and will immediately answer the question of how to get the downhole pump out of the well for maintenance.
Now we tightly tie the pipe, cable and cable together with special clamps so that we get one whole route.

We lower the unit. The places where it clings to the walls are carefully overcome with rotational movements.

We fix the position of the pump below the dynamic water level, but at a height of at least a meter from the bottom. This will prevent sand and other small particles from being sucked into the system.
From above, we install a knee that directs the pipe towards the house and hermetically closes the shaft to prevent oxygen and precipitation from entering it, which contribute to the corrosion process.

To the building we dig a trench with a depth below the freezing of the soil. Depending on the region, it can vary from fifty centimeters to one and a half meters.
We connect to the water supply system at home and use clean and free water from the well.

The arrangement of a well is an ideal way to arrange a private “water supply” on the site of a country house or in a country house with the possibility of fully providing the home with water. The quality of the object being created in modern conditions can be ensured both in winter, in the usual strong and severe frosts in Russia, and in the warmer summer season.

For this, for example, a borehole adapter was invented, as well as a well-functioning and ideally suited principle of operation of the water supply system on the site with the house. The well arrangement scheme is not as complicated as it might seem at first glance, so it can be equipped in a short time.

The principle of the well

Scheme of the design of the well and its typical arrangement

Regardless of the type of your well, the principle of operation of all water wells is identical and is as follows:

After drilling, the walls, in order to avoid shedding, are reinforced with a casing pipe;
For primary purification of water from sand or other solid inclusions, a filter is installed through which water enters the well;
The mouth is sealed with a cap;
The pump lifts the water through the water pipes;
The water pipe is connected to the water pipe, and the well is insulated, depending on the method chosen;
The necessary equipment for automatic water supply is installed.

Equipment selection

The choice of equipment for arranging your future well is one of the most important stages, since the quality and duration of its work will depend on the right choice. The most important equipment that you should pay attention to is the pump, caisson, wellhead and hydraulic accumulator.

The principle of arrangement with a caisson or adapter

The caisson can be called the main design element of the future well. Outwardly, it resembles a container similar to a barrel and is used to protect equipment from groundwater and freezing.

Inside the caisson, you can place all the necessary components for automatic water supply (pressure switch, membrane tank, pressure gauge, various water purification filters, etc.), thus freeing the house from unnecessary equipment.

The caisson is made of metal or plastic. The main condition is that it is not subject to corrosion. The dimensions of the caisson are usually: 1 meter in diameter and 2 meters in height.

In addition to the caisson, you can also use an adapter. It is cheaper and has its own characteristics. Let's look below at what to choose a caisson or adapter and what are the advantages of each.

All additional equipment can be placed inside the caisson.
Best suited for cold climates.
Durable and reliable.
Quick access to the pump and other equipment.

To install it, you do not need to dig an additional hole.
Fast installation.
Economical.

The choice of caisson or adapter also follows from the type of well. For example, if you have a well in the sand, many experts advise you to pay attention to the adapter, since the use of a caisson is not always beneficial due to the short life of such a well.

Pump units

One of the key elements of the entire system is the pump. Basically, three types can be distinguished:

Surface pump. Suitable only if the dynamic water level in the well does not fall below 7 meters from the ground.
Submersible vibration pump. A budget solution, it is rarely used specifically for a water supply system, as it has low productivity, and it can also destroy the walls of the well.
Centrifugal borehole pumps. Profile equipment for water supply systems from a well.

Borehole pumps are widely represented on the market by a large variety of manufacturers, for every taste and budget. The selection of the characteristics of the pump takes place according to the parameters of the well and directly to your water and heat supply system.

Basic design of borehole pumps: electric motor at the bottom, pumping part at the top

It is important to note that in the event of a pump failure, you will bear the cost of not only buying a new one, but also lifting the broken one from the well and installing the purchased one back. Therefore, the choice of the manufacturer should be approached with all responsibility.

Accumulator and relay

The key function of this equipment is to maintain a constant pressure in the system and to store water. The accumulator and pressure switch control the operation of the pump, when the water in the tank runs out, the pressure drops in it, which catches the relay and starts the pump, respectively, after filling the tank, the relay turns off the pump. In addition, the accumulator protects plumbing equipment from water hammer.

Hydraulic accumulators are of horizontal and vertical type

In appearance, the accumulator is similar to a tank made in an oval shape. Its volume, depending on the goals, can range from 10 to 1000 liters. If you have a small country house or cottage, a volume of 100 liters will be enough.

Hydraulic accumulator - accumulates, relay - controls, pressure gauge - displays

Well cap

To equip the well, a head is also installed. Its main purpose is to protect the well from the ingress of various debris and melt water into it. In other words, the cap performs the function of sealing.

Stages of creating and arranging a well

Do-it-yourself well construction takes place in several stages, allowing you to extract water on the site. These include the following actions.

Scheme of arranging a well for water

Training

The first stage is preparation, when it is only planned how to equip the well and its final operating principle is indicated, as well as the main operations are carried out.

A pit is being developed, the bottom of which is leveled with sand, a pump is carried out to the water level, which will subsequently be connected to the main pipe, the main source that supplies water to the site.

At this stage, a safety cable is used, after which everything is attached to the head of the well along with the creation of tie-ins; a final trench is being laid to the house to create a convenient water supply in the country house where work is being carried out.

Roem a pit for a well. First stage

Installation work

The second stage is the main installation work. First of all, a caisson is installed, but, if a well is created without a caisson, this stage changes somewhat, instead of a water-insulating caisson, an additional adapter is installed to bypass the water, or the so-called “piping” is carried out, its complex connection to the entire pump system for protection him from the water; by the way, it is a high-quality adapter that is the main trick that allows you to abandon the caisson, everything is fixed hermetically using a head

A hydraulic accumulator is installed, supplemented by a pressure switch, after which communications through a pre-prepared trench are brought directly to the dacha, bathhouse, sauna or any other building where water access is needed. A high-quality well can provide water not even in one dacha, but become a central water supply for several neighboring houses.

Installation work. Second phase

Let's take a closer look at the installation of all the necessary equipment for the well

Installation of the caisson

Before proceeding with the installation of the caisson, you must first prepare the pit. Of course, the dimensions of the pit must correspond to the dimensions of the purchased container. After you have loaded the caisson into the pit, only its cover should remain at ground level.

If groundwater is present at the site of the future well, additional recesses should be provided so that, if necessary, timely pumping is carried out.

Only after the caisson has been lowered into the pit and secured, can the casing be fixed.

Submersible pump installation

The submersible pump is the most important element of the well, and when installing it, it is necessary to take into account some of the nuances:

Before finally installing the pump, thoroughly clean the well. It must be pumped in such a way that the water does not precipitate in the form of sand and other small particles.
Experts recommend installing the pump so that it is completely under water and does not touch the bottom. The minimum distance of the submersible pump from the bottom of the well must exceed 1 meter.
Install a non-return valve should be a meter from the pump on the riser pipe.
With the help of special automation and a dry running sensor, you can protect the pump from running without water.
It is important that the cable, thanks to which the pump is attached to the head cover, is strong and protected from corrosion.

Installation of a hydraulic accumulator

If you want to provide your site with an uninterrupted supply of water, then the installation of a hydraulic accumulator is required. This type of equipment can be installed both indoors and in a caisson. The technology of the system is quite simple. After the pump has been turned on, water is supplied to the empty tank. If you turn on the tap, water is supplied there directly from the accumulator, and not from the well.

The installation of the accumulator must be carried out in such a way as to ensure unhindered access to it in the future. You should also provide a check valve and a tap to shut off and drain the water.

Final settings

The third stage consists in the final settings that allow you to adjust the operation of the entire system, the optimal pressure is checked and set, the pump itself is connected directly to the electricity network, the system is started for the first time, tested and corrected if problems are found, pipes and insulation are checked again for leaks .

If you plan to equip the well with your own hands, it is better not to neglect the preparatory work and seek advice from experienced and proven specialists who have already received good reviews.

They will help you choose the best place to organize a water source, as well as recommend the best pump that can cope with a specific volume of liquid, and an adapter, as well as put an end to the question of the need to install a caisson and help solve many other problems, explaining the principle of operation in as much detail as possible.

Necessary equipment for well construction

Among the necessary equipment for creating a well in a country house, a fairly large number of elements are needed, among which a special place is occupied by:

A pump designed directly to receive water from a well, as well as parts without which the pump piping will not be completed.
Downhole head designed for complete sealing of the main casing pipe.
Pressure switch that allows you to control the pump and monitor the status of its operation.
Steel cable, necessarily made of stainless material, and always the same stainless cable clamps.
PE water pipes, necessary for the construction of a water supply system, subsequently used exclusively for household purposes.
A non-return valve for water that allows fluid to pass in only one direction - towards the house or any other building, for which a private borehole water supply system is created.
Nipples, preferably brass, threaded at the ends and connecting pipes to each other, as well as other types of fasteners and connections, correctly selected for a particular project.
Directly a hydraulic accumulator that transfers the volume of fluid in the right direction under pressure.
Tees that allow you to create branches from the main water pipe.
A manometer that also allows you to control the water pressure in the pipes.
Hoses and faucets that make it possible to direct water to the right points in the house.
Various consumables, such as sealant, electrodes and others.
The caisson itself, a waterproof chamber that protects devices at depth from water entering them from a well.
An adapter that leads pipes through the main casing pipe of the entire created well, as well as an additional adapter required for sealing in case of failure of the caisson.

The largest and most expensive part is the caisson, the rest of the equipment can mostly be called consumables, the amount of which depends on the size of the system being designed.

A properly organized well will become a permanent source of water, independent of the season - so that even in winter there will be a constant stream of clean water in the country house, suitable for any purpose and providing comfortable living conditions in a private house.

In addition to proper organization, well-chosen equipment, such as a borehole adapter, also ensures a high water level and longevity of well use, so it is also worth paying attention to when preparing a project.

Well drilling in the area near the country house is completed. The next question facing the owner is the choice of a pump that would be able to extract and transfer water to users as efficiently as possible. The best solution is to purchase a submersible pump for the well. This article will help you decide on the model and the main characteristics of the device.

How to choose a well pump

Water submersible pumps for wells are selected based on:

device types that differ in the principle of operation;
well parameters;
equipment specifications.

Types of submersible pumps

How to choose a device that is most suitable for a well in a suburban area? First of all, you need to decide on the type of pump.

All submersible pumps according to the principle of operation can be divided into several types:

centrifugal;
vortex;
vibration;
screw.

A submersible centrifugal pump for a well works by creating a turbulent flow by rotating diffusers.

Centrifugal pumps are easy to use and require no special maintenance. The cost of the equipment is relatively small. However, the device also has negative aspects, which include:

the need to install an additional filter at the bottom of the well. Centrifugal type pumps are very sensitive to the ingress of various impurities and / or small particles into the device;
it is required to put the device into operation after filling the pump with water. Running the pump "dry" will damage the equipment.

One of the varieties of centrifugal devices are those capable of pumping both clean and slightly clogged water.

Centrifugal submersible pumps can be used for both deep and small wells.

The vortex-type submersible borehole pump raises water by mixing the air supplied to the chamber through a special pipe and the working fluid.

Vortex pumps are characterized by low power, therefore they are used only for shallow wells.

The principle of operation of the vibration pump is based on the movement of the rod due to electric current.

The advantages of the vibration pump are:

reduced requirements for water quality. The device is capable of pumping water with minor impurities without compromising wear;
high reliability achieved by simple design.

Along with the significant advantages of the equipment, there are also disadvantages of the device, which include:

the vibration created by the pump negatively affects the walls of the well. If the walls are not fixed with specialized materials, then they are gradually destroyed;
small working depth.

Vibratory pumps must not be installed below 5 m from the ground level.

A screw-type submersible borehole pump consists of a housing (stator) inside which a helical rotor rotates. When the rotor rotates, water is taken from the well and fed into the pipeline.

Screw pumps are capable of lifting water from a depth of 40 - 50 m, but due to the increased friction created inside the structure, the equipment requires periodic cleaning and replacement of working parts.

Screw pumps are mainly used for industrial purposes.

Well parameters affecting pump selection

The selection of a submersible pump should also be based on the parameters of the well, which can be obtained from the technical passport of the structure, issued after manufacture, or measured independently using a load and a long rope. The main parameters that matter when choosing a pump include:

depth, defined as the distance from the surface of the earth to the bottom of the well. This indicator is necessary to determine the pressure of the device;
the borehole diameter is needed to determine the diameter of the equipment. The pump should not touch the walls of the well, but should not have a too small diameter, as this affects the performance of the device;

The optimal diameter of the pump is 20-30 mm less than the diameter of the well.

well debit. The indicator determines the volume of water that can be raised from the well per unit of time. The correct determination of the debit affects the choice of pump power. Exceeding power over debit can lead to "drying" of the water source;
static and dynamic water levels. The statistical level determines the constant amount of liquid in the well. The dynamic level is calculated based on their constant consumption. These indicators are important to consider when choosing a pump for determining the level of immersion.

Definition of technical parameters

The technical characteristics of the pump, which should be paid attention to when choosing a submersible pump, are the following parameters:

equipment performance. This parameter shows how much liquid the pump can pump in a certain unit of time. The capacity can be calculated in m³/h. The performance calculation is determined on the basis of consumption rates and plumbing fixtures installed in the house on the basis of consumption rates developed by specialists;

the head that the pump can lift water. When calculating the indicator, the depth of the well and the length of the pipeline should be taken into account, and 10 m of length increase the height indicator by 1 m. To provide an additional reserve, it is recommended to increase the obtained indicator by 5 - 12 m. For example, the depth of the well is 10 m. A pipeline 20 m long is used for drainage The minimum head of the pump must be 10+20/10+10=22 m.

A good submersible well pump must meet all the necessary requirements.

Without determining the main parameters, it will not work to select a submersible pump.

Additional parameters for pump selection

To determine which pump is better, it is also recommended to rely on additional parameters, which include:

water quality. If the water contains a large amount of impurities, then it is more advisable to purchase a device equipped with additional filters or choppers;
ways to start the equipment. If the well is located near the house, then the pump can be turned on by hand. If the well is located at a considerable distance from the buildings, then it is better to purchase a submersible pump for the well with automation, that is, the device will work depending on the water flow;
cost of equipment. It is not recommended to purchase cheap devices, as in the case of submersible pumps, the famous saying "the miser pays twice" applies.

Rules for installing a submersible pump

Installing a submersible pump in a well does not cause problems even for an inexperienced user. Each device is accompanied by detailed instructions for installation and use of equipment.

The equipment is installed according to the following scheme:

at the first stage, it is necessary to purchase all the components: a pump through which water will rise, a cable for fastening, an additional electrical cable, a check valve if it is not included in the pump kit;
before installation, it is necessary to assemble the structure into a single whole. Work begins with the installation of a check valve that prevents the fluid from flowing back;

When installing a non-return valve, pay attention to the flow of water. It is usually indicated by an arrow on the hardware itself.

Next, a pipe adapter is installed. All connections must be sealed with fum tape;
at the next stage, a pipe is connected, designed to raise the water of their well;
every 80 - 100 cm, a power cable is fixed to the pipe. This can be done using insulating tape or specialized clamps;

The cable cannot be attached to the pipe in a stretch. It should be slightly loosened.

a steel cable is attached to support the pump in the well;

the pump is lowered into the well to a previously determined level;

the power supply is connected;
a cap is installed on the upper part of the well to prevent its pollution.

You can learn more about the process of installing a borehole pump by watching the video.

The choice and installation of a borehole pump should be treated with the utmost attention. Incorrect selection of equipment, as well as incorrect installation, will lead to the inoperability of the entire water supply system.

If the garden can be watered from shallow reservoirs using surface electric pumps, the simplest low-power vibration pumps, submersible drains, then the situation is different with the constant water supply of a country house from a deep well. High-performance devices are required, capable of extracting water from great depths with high pressure, while their efficiency should be quite high. All these requirements are fully met by centrifugal submersible electric pumps, the most widely used in domestic water supply.

The principle of operation and the device of centrifugal electric pumps

The main element of a centrifugal pump is an engine hermetically placed in the body of the apparatus, and an impeller in the form of a disk with a one-sided impeller, mounted on its shaft. During operation, the liquid is drawn in through the inlet of the housing, located in the central part of the impeller, and its radially curved blades push it to the periphery. The water is collected in a snail-shaped annular collector and is forced out through the outlet pipe under pressure by the next flow of water entering the housing.

Rice. 2 The principle of operation of a centrifugal type deep-well pump

To increase the pressure in the system, several wheels with separate chambers and outlet pipes, called stages, are often used, from each of them to the next the liquid is transferred with increasing pressure. Centrifugal pumps are highly efficient and can handle turbid water.

Rice. 3 Centrifugal water pump device

The device of a centrifugal type submersible pump of a standard industrial design, made in accordance with GOST, is as follows:

Frame. In the domestic pump, it is made of a steel pipe with thick walls - this gives the unit high rigidity and strength. For massive devices, the rod method of fastening in the well is used.
The impellers are designed with dynamic unloading - this led to a decrease in the pressure forces on the axial bearings, and significantly increased their service life.
Centrifugal wheels are made using a patented technology of durable plastic reinforced with stainless steel - this increases their service life.
To improve the removal of sand from the mechanism, octagonal bearings are used.
The inlet of the pump is closed by a perforated built-in stainless steel filter.
The shaft of the electric motor, on which the impellers are placed, is also made of stainless steel.
The "squirrel cage" assembly of the electric pump rotor is made of copper alloy - this increases the reliability and performance of the electric motor under heavy loads.
The significant length of the stator and rotor is designed to increase the reliability of the electric motor, reduce its susceptibility to fluctuations in the supply voltage, and improve cooling conditions.
Self-aligning angular contact bearing absorbs axial pressure.
The winding copper wire of the stator with a high-temperature insulating coating (up to 100 C) in the form of insulated bundles is placed in its grooves, the production technology reduces the response of the electric motor to voltage surges and increases its service life.
The built-in non-return valve prevents the wheel from rotating in the opposite direction, keeps water in the system, making it easier to start the electric motor and preventing water hammer.

Distinctive features of Grundfos centrifugal electric pumps

The Danish company Grundfos is considered the world leader in the manufacture of pumping equipment, so its products are a benchmark for any manufacturer and have significant differences from domestic counterparts. Using the example of its electric pumps, it is possible to show what design a good submersible well pump should have and what functions it should perform. The devices are designed for water intake in a well or a well with a considerable depth and have the following features:

Rice. 5 Appearance of Grundfos electric pumps

The body is made of durable stainless steel, impellers and some internal parts are made of heavy-duty polyamide.
The modular design of the electric pump includes three components: control electronics, a module with a motor, a block of centrifugal impellers - this makes it easy to disassemble and assemble the device.
The unit is designed to work with clean drinking water, so the material of the impellers and internal parts does not adversely affect the composition of the water.
A very durable housing allows you to lower the electric pump to a considerable depth, unlike domestic models, oil is not squeezed out of it.

Rice. 6 Grundfos SP and SQE borehole pump design

The cable winding is made of rubber, produced and certified in Germany. The material is designed for use in drinking water.
Electric pumps are easy to manage - on the control unit CU-301 you can set the operating mode of the device - change the pressure, stop the pump in the well, if there is a problem in the system, the red indicator lights up on the unit and the electric pump stops.
The submersible pump device includes overload protection - when water is supplied to a filled system or when pipes are clogged, the electric pump is turned off.
The device is equipped with a dry-running protection that turns it off in the absence of water.
There is protection against power surges - the pump goes into emergency mode when their values are more than 315 V. and below 150 V.
The devices have built-in non-return valves made of plastic.

Rice. 7 Grundfos electronics

The electronic system of soft start of the engine with permanent magnets built into the well pump reduces the wear of parts and elements of the water supply system after hydraulic shocks during repeated starts and stops of the electric pump.
Due to the higher efficiency, Grundfos spends less energy to lift the same volume of water as other pumps. The frequency converter, built into the electric pump and controlling the speed of rotation of the impellers, allows you to save electricity up to 40% of the standard counterpart.
The reliability of Grundfos is very high, they can work in wells up to 20 years in the most difficult conditions.
The principle of operation of the Grundfos SQE submersible pump allows you to change the shaft speed from 65% to 100% - this allows you to configure the devices individually for each well.

Centrifugal electric pumps are the main devices for providing water supply to country houses. In the case of deep wells with severe operating conditions, the price-quality-reliability ratio of pumps from a well-known foreign manufacturer may be better than that of domestic analogues.

It is difficult to overestimate the importance of a deep pump in the water supply system of a country house, especially if the well is the only source of water. A competent choice and high-quality installation of a water supply device allow a long and uninterrupted use of an autonomous system.

An excellent assistant for residents of rural areas, summer residents and owners of country houses often become Aquarius deep pumps from the Promelectro company. A wide range of models allows you to choose a pump that meets specific operating conditions, and increased performance and an adequate price of equipment make Aquarius pumps in demand among buyers.

Deep pumps Aquarius - balance of price and quality

Submersible pumps "Aquarius" have been manufactured by the Kharkov company "Promelektro" since 1996. The company produces a whole series of household electric pumps with a lifting height of up to 200 meters and a capacity of up to 12m3/hour. Technical and operational characteristics allow the use of downhole equipment for pumping water from sand and artesian wells.

The advantages of Aquarius pumps include:

The price of the Aquarius deep pump depends on its technical characteristics and ranges from 7,500 to 17,500 rubles.

Aquarius deep-well pumps comply with the IEC 335-1 international safety standard and are not inferior in quality to similar borehole pumps of European brands GRUNDFOS, CALPEDA and PEDROLLO. Among the manufacturers of the CIS countries in terms of quality, pricing policy, design, demand and reliability, Aquarius pumps have no analogues.

The device and principle of operation of the deep pump Aquarius

Consider the device of the Aquarius deep pump. The electric pump consists of a multi-stage pump part, an electric motor and a remote condenser box.

The electric motor is filled with oil and consists of a rotor, stator and rotating ball bearings.

The pump part is represented by a monolithic block, which contains blade outlets, working and guiding wheels, as well as a drive shaft. Cap with female pipe thread keeps all parts in place. The cover has holes for attaching equipment with a cable.

The diameter of the impeller determines the performance of the pump - the volume of water that the pump can lift in a certain period of time

Cap with female pipe thread keeps all parts in place. The cover has two holes for attaching equipment with a cable.

The capacitor box contains the power cord and capacitors that ensure the operation of the electric pump.

Aquarius pumps use reliable German automation that protects equipment during critical operating conditions. An external device for remote control is attached to the power cord.

The principle of operation of the deep pump Aquarius centrifugal type is as follows. As a result of the rotation of the impeller, kinetic energy is generated, which is transferred to the blades and acts on the particles of the substance, that is, water. The liquid in the impeller area rises to the upper part of the pump housing, and the new one, under pressure, enters its place. The water transition is supported by constantly rotating wheels.

Borehole pumps Aquarius: models and their characteristics

The Promelectro company produces various series of deep pumps Aquarius. All the most significant characteristics of the model can be found from the very name of the pump. For example, the pump BTsPE-0.5-32U 60/47:

BTsPE - household centrifugal submersible pump;
0.5 - equipment productivity (0.5 l / s);
32 - nominal head at nominal volumetric flow, indicated in meters;
60 - the highest productivity (60 l / min or 3600 l / h);
47 - the height of the rise of water at maximum pressure.

All centrifugal downhole pumps for the Aquarius well are classified by performance into four groups:

BCPE-0.32;
BCPE-0.5;
BTsPE-1,2;
BCPE-1.6.

Series pumps BCPE-0.32 designed to work in low-yield wells, wells, with a diameter of 120 mm.

BTsPE-0.32 pumps are suitable for household use if water consumption does not exceed 2 m3/h. It should be noted that the nominal water flow in normal mode is about 1.15 m3/h

The range of the series includes nine models that differ in nominal head, power consumption, dimensions and cost. Consider the technical characteristics of the Aquarius deep pump using the example of the BTsPE-0.32-63U model:

the estimated price of a deep pump 63 U of the BTsPE-0.32 series is 10,500 rubles.

Each set of pumps of this brand includes a strong nylon cable for mounting the pump in the well and a long electric cable.

Deep pump series BCPE-0.5 have an additional function - protection of the electric motor from overheating. The submersible unit can be used both in the automatic water supply system and in manual mode.

Pumps of the BTsPE-0.5 series can be used in boreholes and wells with a volume of incoming water of at least 25 m3 / h and a diameter of 110 cm. In addition, such pumping equipment is suitable for pumping water from mine wells, reservoirs and open reservoirs

The series reads eight modifications of pumps: the smallest nominal head is 16 meters, the largest is 100. Consider the characteristics of the Aquarius 16 deep pump from the BTsPE-0.5 series:

productivity - 0.5 m3/s;
head at nominal flow - 16 m;
voltage - 220 V;
network frequency - 50 Hz;
current consumption - 1.8 A;
maximum head - 27m;
rated power consumption - 400 W;
rotation speed - 2800 rpm;
device weight - about 8 kg;
a 400 V capacitor has a capacitance of 14 uF;
number of work steps - 3;
Estimated cost - 7000 rubles.

Pumps of this series are able to provide an uninterrupted supply of water for watering the garden, vegetable garden and domestic needs.

Deep Aggregates Aquarius BTsPE-1,2 can be used in wells and wells with an internal diameter of 120 mm. The pump is recommended to be used for supplying water with a temperature not exceeding 35°C.

Water should not have a mineralization of more than 1500 g/m3 and contain a large amount of sand. Pumping acidic, alkaline solutions and liquids is prohibited

The series is represented by eight models (minimum feed pressure - 12 meters, maximum - 80). Technical characteristics of different modifications are presented in the table.

Pumps from the series have the highest performance BCPE-1.6. The equipment is produced in three models with a total head at a nominal flow - 25, 32 and 40 meters.

Installation and connection of the Aquarius pump

When installing BPCE Aquarius, some general recommendations for the installation and operation of submersible pumps should be taken into account:

The remote condenser box should be located under a canopy or indoors.
During operation, the pump must be completely immersed in water.
The distance from the pump to the bottom of the well is at least 40 cm.
The first switching on of the electric pump can be made not earlier than 5-10 minutes after the complete immersion of the equipment in water.

Consider the step-by-step process of installing and connecting the Aquarius pump:

Carefully lower the electric pump into the water, holding the cable and pipeline. It is necessary to control that the power cord does not experience tension.

Before turning on the pump, make sure that it is completely immersed in water.

Deep pump maintenance

Aquarius deep pumps are designed for a long service life, and the uninterrupted operation already depends on the user himself. Compliance with the operating rules and periodic inspection is a guarantee that the pump will work for many years.

Once every two years, the pump must be pulled out of the shaft and inspected. It is necessary to lift the unit as carefully as possible so as not to break the pump flask against the walls of the well. The extracted pump is checked for cracks and chips. The appearance of such defects can lead to the expansion of water during the freezing of the source.

The motor shaft should rotate smoothly and easily. If the motor shaft scrolls with difficulty, then the bearings must be replaced. If necessary, add oil and oil seal. The motor winding should be inspected for signs of overheating.

The disassembly of the Aquarius deep pump must be carried out carefully - the cable insulation becomes fragile over time and can be easily damaged

With reduced pressure, it is necessary to change the impellers - most likely they are worn out. It is better to entrust this work to specialists.

Possible breakdowns of the pump and the procedure for their elimination

Consider possible malfunctions, causes and procedures for their elimination.

The pump does not turn on.

Possible causes and remedy:

Reduced pump performance.

pipeline rupture and fastening failure - lift the pump and check the integrity of the pipeline, eliminate defects;
the filter holes are clogged - raise the pump and clean the filters;
a sharp drop in voltage - ensure normal voltage - 220V.

The safety device trips after a short period of operation.

We will analyze the step-by-step repair of the Aquarius deep pump if the unit is clogged:

Remove protective mesh. If it is fastened with a special clip, then you need to press down a little in the middle and pry off the mesh with a screwdriver. On some models, the mesh is attached with two ordinary screws, which are easy enough to unscrew.
Remove the cable channel - a metal groove that protects the cable from damage. This element is present in wide models of pumps.
Separate the pump part from the engine - unscrew the four bolts with a 10 wrench and remove the plastic couplings.
Carefully lay the disassembled structure on a horizontal surface.
Turn the shaft with a socket wrench while holding the top of the device.
Rinse the pump thoroughly and reassemble it.

How to choose the Aquarius pump

The correct choice of the pump is the key to its long-term operation. When choosing the optimal model, it is necessary to take into account the characteristics of the well and observe certain conditions:

the flow rate of the well must exceed the productivity of the pump, since over time the flow rate of the source decreases due to silting;
determine the required pressure of the electric pump based on the distance from the water intake point to the accumulator and the pressure loss in the horizontal section of the pipeline.

According to the pressure characteristics graph, you can determine the appropriate model of equipment.
