Submersible sand well pump. Types of borehole pumps for water with sand. Quality pumps at a higher price

If you decide to make your own source of water for yourself and drilled a well, and the first layer of water is drilled, then you need to carefully consider the choice of pump. Not every unit can pump water that is contaminated with sand. It happens that the smallest particles of sand get into the pump, and this leads to its malfunction. Flushing equipment, which is done in such cases, will not help.

What type of pump is best suited for such a source and the right choice of pump

To understand what better pump will function for such a source, you need to know the characteristics and properties. In such a situation, sand deposits are an aquifer. Due to the fact that the sand has a high porosity, then, accordingly, the grains of sand move actively. It turns out that when water moves in the reservoir, enters the well and the deep pump operates, the sand rises and enters the already pumped water. Because of this, water supply is possible. dirty water.

Such a process negatively affects the pump motor, pumping dirty water, puts heavy loads on it, which it cannot withstand for a long time, and subsequently burns out. After that, it cannot be repaired. If in doubt which pump is best to choose, then seek help from a specialist who can give useful advice and advise on this choice. You can buy a pump for a well in the online store: "World of Pumps" by clicking on the link nasos-od.com.ua

On a note! It is worth knowing that in order to provide additional protection of water and the pump itself from pollution, specialists who are engaged in drilling wells and their arrangement make a natural filter from fine gravel and pebbles. This stops the movement of sand in the well itself. Also at the end casing pipe the strainer is attached.

Vibrating pump

Such a pump is not recommended to be immersed in wells on sand. This device is not designed to process dirty water. The pump performs oscillatory movements during operation, and this only activates the movement of grains of sand. By installing such a pump, the well may become clogged with sand, then you will have to turn to the help of specialists to flush it.

Surface pump

Designed for shallow wells, no more than nine meters, not intended for processing dirty water. Even the slightest hit of grains of sand can lead to its breakage. Surface pumps are often used for summer cottages, wells or wells with little depth.

Centrifugal pump

This type of pump is perfect solution for a well in the sand. He is not afraid of sand or clay, he copes with such pollution easily, which does not harm his work, and therefore, his service life will be long.

Water enters the outlet due to the rotation of the blades. The centrifugal force that appeared inside the unit supplies water from the well to the pipe. Such a device pumps contaminated water. From user reviews, we can say that up to 1.5 kilograms of pollution is pumped per cubic meter of water. In any case, you need to install well filtration, it’s not worth the risk, since such equipment costs a lot of money.

screw pump

This one is not scary heavy pollution from sand and clay, it can pump up to two kilograms of sand per cubic meter of water. They are used both for shallow wells and for wells of great depth, it can be up to 300 meters. This does not affect the performance of this device.

From the right choice pumping equipment for a well, its productivity, durability, and sometimes the operating life of the hydraulic structure itself will depend.

MAIN TYPES OF PUMPS AND THEIR FEATURES

• Vibrating- are more often used in wells, since as a result of vibrations they can not only lift sediment from the bottom, but also damage the walls of the wells
• Centrifugal submersible- I've made sure that it's the best solution for wells. During operation, a minimum of vibrations is formed, the productivity is quite large, as is the height of the water rise, and overheating is excluded due to the design features of the engine
• Drainage or self-priming– their use is relevant for shallow wells or as dehumidifiers for caissons

selection of a pump and equipment for a well, criteria

• Water lifting height- these are the total values ​​​​of the depth of the well (from the point of immersion of the pump to the surface of the earth) and the height of the top point water intake from ground level. The coefficient of horizontal movement of water is also taken into account if the hydraulic structure is located at a sufficient distance from the house (20-30 meters)
• Well type(on sand, artesian) and casing material - we have experienced in practice the damage that vibration pumps can cause to a PET pipe or downhole filter
• Volumes of water consumption and maximum total loads
• well flow rate
• Water quality in the well and the presence of solid impurities in it

I advise you to rely on the experience and qualifications of professionals in this matter. We will select a suitable pump, offer it to you at a dealer price, and carry out professional installation.

Now I will answer the questions that our clients most often ask us.

Which pump is best for a well?

Based personal experience, I can say that for wells, regardless of their depth, the material of the walls of the casing string and the type of bottomhole filter, it is better to use centrifugal (vortex) submersible pumps.

Why?

During operation, they do not vibrate, so they do not raise sediment from the bottom, and most importantly, they are not able to damage the walls of the casing string and the downhole filter. They are also highly efficient and, unlike vibratory pumps, can run longer continuously.

Important!

How to choose a pump The basis of choice is the productivity of the well in relation to the consumption volumes (peak and average).

What types of wells do we drill

Advantages of centrifugal submersible pumps

Centrifugal pumps cannot physically overheat, as the water passes through the motor, which consists of a freely rotating rotor due to the force of electromagnetism, and a stator. There is a stream moving between them. cold water providing natural cooling.

If there is no more than 10-15 meters to the water surface from the surface, you can use self-priming pump, but there are a number of difficulties here, including the need for its additional maintenance and control.

Below I will review the characteristics of several centrifugal pumps in comparison with a vibrating counterpart, so that it is easier for you to understand the difference in performance.

Pump Model	Power	lifting height	Productivity l/h	Immersion depth	Price
Vibration pump BELAMOS BV012, 25 m	300 W	70 m	990 l	3m	2800 rubles

Dzhileks Vodomet PROF 55/75 House (set for automatic autonomous water supply)	900 W	75 m	3300 l	30 m	26000 rubles

As you can see, the characteristics of the pump directly affect its price, but in each price category There are different types of pumps. I have been convinced more than once that only a professional can determine the priority selection criteria.

Common mistakes when choosing and installing a pump

So what not to do?

• “The neighbors have one of these, which means it will suit me too” – classic mistake. Two wells located 20-50 meters apart can vary greatly in flow rate. In addition, it is important to take into account such factors as material, casing diameter, bottomhole filter type, consumption volumes.
• "I'll buy more powerful - in reserve" is another common misconception. First, why pay more? Secondly, a pump that is too productive can ruin the well with low flow rate salvo pumping. We often had to repair a well, the water quality of which was lost precisely because of the wrong choice of pump
• "I'll do all the calculations myself"- even many of my colleagues who have switched to free bread do not always make calculations with high precision There are too many factors to take into account. Better leave it to the professionals

Classic when installing pumping equipment yourself:

• Not right choice installation depth
• Incorrect fastening of the pump on the carrying cable, as a result of which part of the load falls on the power cord
• Incorrect connection to the mains

IMPORTANT!

Do-it-yourself installation - is it necessary? I strongly recommend not to regret one or two thousand rubles for the work of specialists who will make all the calculations and carry out the installation correctly.

The optimal installation depth of the pump between the bottom and the water surface for standard water intake

Here we completely turn off the fantasy - the installation depth of the pump is a constant value recommended by the equipment manufacturer. The nuances take place only for high-performance models with a large installation depth. In this case, at least one meter of water column must remain to the bottom of the well.

At what depth should a submerged pump be installed for pumping a well?

At the stage of pumping a well, we always pursue the same goal - to pump out sand and turbidity from the bottomhole. It is irrational to do this with a centrifugal pump, since they are very sensitive to the presence of fine solid impurities in the water.

Therefore, for pumping (if possible), a vibration pump with a lifting height of up to 80-110 meters is used.

They are not afraid of sand, and they can be installed almost at the very bottom in order to pump out unnecessary dirt from the well to the maximum.

If the well is pumped by a centrifugal pump, then at least one meter must remain to its bottom, as required by the instructions for the equipment.

Dry running protection for borehole pump

Imagine such a situation - you are not at home, a tap leaked, and as a result, the pump pumped out all the water from the well and continued to work.

The result is the replacement of expensive equipment, since the plastic impeller will not withstand high temperatures. If it is protected from dry running - relays, special floats and automation, then such incidents are excluded.

Cable conduit for borehole pump. submersible pump cable extension for a well

I can assure you that you will not find a pump that comes with an electrical cable of the same length as the lifting height for which it is designed, because 120 meters of cable is a lot. The maximum that the manufacturer offers is 15-30 meters.

How to be? Ramp up! I categorically do not recommend doing this on your own, but if you still decide, then here are some of my professional tips:

• Use a submersible cable- yes, it is a little more expensive, yes - there will be no disaster if you take a regular one, but if for some reason damage occurs in a simple cable, the consequences can be serious. Submersible is designed for direct contact with water, it is better
• The connection must be on maximum height from the water surface - do not cut the cable just before entering the pump - cut the plug
• Use special connectors and epoxy resin for hermetically sealed joints or special heat shrink sleeves
• Use an appropriate cable section corrected for resistance along the length

In general, everything is not simple here either, so I recommend leaving this work to specialists.

Pump and automation for sand wells

Wells for sand in the Moscow region are used mainly for irrigation in garden plots.

The flow rate in such wells is usually low and variable, and the water quality is low, as it contains a lot of sand.

The optimal solution is a submersible vibration pump. It is affordable, picky about water quality.

The subtleties of installing a vibration pump
When installing the pump, it is important to fix it so that it does not touch the walls of the casing string or bottom filter, otherwise vibrations can lead to mechanical damage equipment or building itself.

We automate the system based on the vibration pump

The easiest option for automatic shutdown such a pump is a switch with a timer.

If you know the flow rate of the well, and it is, for example, 500 liters per hour, and your pump pumps this volume in half an hour, then simply set the timer for 20 minutes to select the desired volume of water, and go about your business.

You can also use a float system.

Inefficient pump for a well with a low flow rate

Wells with low flow rates present a serious problem. I often came across the fact that people are looking for low-performance pumps as a solution, but you will not find them, because even the smallest pump has a minimum capacity of 450 liters per hour, and if the well flow rate is 250 liters, then this discrepancy is almost doubled.

What to do? I suggest the following solution:

• We install a storage tank for 500-1000 liters in the basement or in the attic. If in the basement, then with a membrane to maintain pressure, if in the attic, then without
• We connect automation to the tank in order to constantly keep it full
• We install automation to protect against dry running in the well

What do we get as a result? Your country house provided with water, because even with a very strong desire, you will not make a salvo discharge of 500 liters. The volume of water in the bathroom is 200 liters, one wash in an automatic machine is 60-80 liters, a toilet tank is 8-15 liters.

The pump works in segments of 5-7 minutes, if necessary, replenishing the tank or stopping work if the water in the well goes below a certain level. Problem solved!

Is a vibration pump harmful to a well?

Harmful, and I'll tell you more, if installed incorrectly, it will destroy the well faster than you think. Vibration is to blame. Sometimes the use of a centrifugal type pump is irrelevant, and in these cases it is important to at least follow the installation rules:

• Install the vibration pump at least 1.5 meters above the bottom of the well
• The pump should not touch the walls of the casing - it should hang freely in the water column
• I also recommend using models with an upper water intake - this way it will disturb the face less

Water hammer when turning on the pump and strong shock when turning it off

Water hammer in the water supply system not only leads to the failure of plumbing, but also the pumping equipment itself. This phenomenon occurs when the pump is directly wedged into the system.

It is easy to avoid this - for this I advise you to definitely use membrane accumulators. They dampen sudden pressure surges in the system, extending the life of your expensive plumbing equipment.

Features of maintenance of pumping equipment

During my career, I have come across this issue many times. In fact, in the case correct installation and operation of the submersible pump does not require additional maintenance. Some models require prelubrication individual elements just before installation - nothing more.

When using centrifugal submersible pumps for pumping water with sand impurities, repair may be required - replacement of impellers. All these works should be carried out only by a professional - on your own you can only do harm.

Pump modeAlways follow the operating mode recommended by the manufacturer, do not overload the pump, then it will work properly throughout the entire operating period.

Borehole pumps for water with sand allow you to get purified and quality water. Thanks to its own water intake source, the owner of the site will not depend on a centralized water supply.

Sand wells are the most common sources, as they are located on the first layer. This design requires careful selection of the pump. The resulting water will initially be heavily polluted with sand, so not every unit will be able to pump it efficiently. This will create an additional load on the pump, so the sand source requires the use of special powerful equipment.

The aquifer is represented by sand deposits. The porosity of the material is large, and therefore the mobility of each grain of sand is also high. Sandy water flow creates an additional load on the pump. The device cannot pump dirty water for a long time, so it burns out quickly. It is beyond repair. What to do in such a situation? The reasons for the rapid failure of equipment is a poor-quality pump.

Specialists in the field of water supply have developed a method for additional protection of water and equipment from sand. When arranging a hydraulic structure, a natural filter made of fine crushed stone or pebbles is used. it good way inhibition of any washing or movement of sand in the entire well. For greater efficiency, a mesh look filter.

Machine description

The sand pump is a single-stage and centrifugal equipment. The main task of this design is the pumping of abrasive slurries, waters with various impurities. But for effective pumping, a liquid must have certain properties.

The pumped solution must have:

• certain temperature (+5…60°С);
• density up to 1300 kg/m³;
• content of solid inclusions (up to 25%);
• maximum microhardness up to 9,000 MPa.

Feedback on such pumps is positive. The sand aggregate is able to work for a long time. It is used in metallurgy, mining, construction enterprises. Such an installation is easily used to clean the trench. A pump for pumping silt or sand can simultaneously perform several tasks:

• clean the trench for its subsequent filling;
• remove sludge, silt, clay, waste;
• clean caissons during construction work;
• restore coastal areas;
• pump out marble dust;
• purify various reservoirs;
• extract sandy elements from the bottom of the reservoir;
• pump out sand from various wells and wells;
• destroy gold mining tailings.

The pump cannot be used for pumping, pumping water and other cleaning work in fire and explosive conditions.

Aggregate classification

Taking into account the throughput of solid particles, pumps are divided into several types:

• gummed - pass particles up to 2 mm;
• corundum - particles up to 1 mm;
• wear-resistant structures made of cast iron pass particles of clay, sand, silt up to 6 mm.

Another classification reflects the location of the shaft (vertical, horizontal). Type P units are console horizontal structures. They are used for pumping or pumping ore beneficiation products. The robust part is made of wear-resistant cast iron. Devices maintain solution density up to 1300 kg/m³. The admissible height of the cavitation reserve is 2 m. The designer must not fall below this height.

Units of type PB (pumps from a well) are either horizontal or console format. But such centrifugal plants allow you to have a cavitation reserve of up to 5 m - these are their main feature and advantage.

The PR model from a well is distinguished by the presence of a corundum main part of the flow path. Often it is on an organic ligament. Types of pumps from the well PKVP, PRVP - cantilever, but vertical structures. This is a submersible view of installations, the supports of which are outside the pumping of liquid. Industrial model EZG slurry pump is the most advanced pump from the well, the durable part of which is wear-resistant rubber.

Surface and submersible units: pros and cons

The pump can be surface or submersible. What is their difference? Surface view - a powerful design that has a rotor. The main task is to pump water or sludge by sucking them through the working chamber. Such a borehole pump can lift slurry from a depth of up to 10 m. The advantages of such a pump:

• easy transportation of liquids over long distances;
• reliability.

Such installations have a number of disadvantages:

• high level of noise and vibration;
• inability to use if the well is deep and wide.

A dredging well slurry pump is a submersible model designed to pump water specifically for a well or well. Before starting work, the structure is immersed under the very thickness of the water. She is there until the completion of all work. Such a device quickly and efficiently pumps water with sand. The advantage lies in working at serious depths of a well or well. The exact data and characteristics are individual, depending on the brand of the manufacturer and model of the equipment.

Design advantages:

• the electric pump has small size and weight;
• can work for a long time without Maintenance;
• can be used in deep wells;
• high performance and efficiency;
• the presence of protection against drainage;
• can work in automatic mode when working with great content sand in the water.

Surface pumps are used for dirty water. Drilling is carried out from the depth of work and cost.

This unit is suitable for operation at shallow depths (up to 8 m).

Other types of pumps

The vibration pump is a submersible equipment that is not applicable to sand wells. Its technical indicators do not imply the processing of dirty water. There is a risk of partial or complete sanding of the installation. This requires thorough flushing and pumping with the help of professionals.

The centrifugal installation is a submersible mechanism. Its action is based on the injection of water into the outlet due to the rotation of the working blades. The main role in this functioning is played by centrifugal force, while water is supplied with high pressure from the well to the water intake pipe.

Experts advise using submersible centrifugal devices for water with sand. Their feature lies in the good ability to pump dirty water. The performance of these designs include pumping fluid with inclusions. But you should not experiment on your own with the endurance of the unit.

The screw submersible pump is capable of pumping sand. It works on the principle of Archimedes (the work of a meat grinder). The screw-type submersible pump is easily mounted in deep wells (up to 300 m). Before purchasing it, you need to study the following parameters:

• average daily volume of water consumed by families;
• well depth;
• parameters of the casing pipe of the source itself;
• well flow rate.

Based on these data, the user can choose a device that is suitable for the planned water well.

The efficiency of autonomous water supply systems largely depends on the correct choice of equipment, when deciding which is better for a well, it is recommended to listen to the opinion of experts and read the reviews of the owners various models aggregates.

The choice of a submersible pump for a well should be based on an analysis of operating conditions, an assessment technical features water source.

First of all, pay attention to the following characteristics:

• The depth of the hydraulic structure and the maximum possible head of the pumping unit.
• The diameter of the casing pipe, and the possibility of using the pump based on its overall dimensions.
• Water quality, many pumps are not designed to pump liquids with large quantity mechanical impurities (sand).
• The required performance of the equipment (expenditure characteristics) must meet the needs of all consumers.

Based on these data, you can choose pumps of various price categories.

Budget pumps

If irregular operation of a well of small depth is expected, then it is quite possible to get by with pumps of an inexpensive price segment. At the same time, it is possible to choose models of domestic and imported production.

Perhaps one of the most popular models of equipment domestic production. The cost of the unit is 5-6 thousand rubles, depending on the configuration and modification.

The maximum productivity is 3.3 cubic meters per hour, while the pump can be operated at a immersion depth of up to 30 meters (maximum head 45 meters).

Differs in high tightness, it is easy in service, it can be established in wells, wells, reservoirs of various type.

Medium range pumps

The list of pumping equipment for wells at an average cost is quite extensive, experts advise paying attention to Gileks products. Units with a power of up to 1.1 kW provide a head of up to 115 meters, while the maximum productivity can be 6.9 cubic meters per hour.

The features of the models include the use of a special filter in the design, which allows the use of equipment even in wells with a significant content of sand in the water. During operation, the device does not create vibration loads that can negative impact for well casing.

Possess high efficiency, they are reliable and durable, operation and maintenance do not require significant financial costs. The cost of various modifications of water cannons of this brand varies from 5 to 15 thousand rubles.

Quality pumps at a higher price

If you need equipment that can last the entire period of operation of the well, you must give preference to more expensive models.

As a rule, such installations are characterized by high efficiency, reliability, and can be operated in various conditions.

Can be purchased for 27-50 thousand rubles. For this money, you will receive an installation that supplies up to 7.5 cubic meters of water per hour, while the maximum pressure can be 155 meters. Considered one of the most suitable types equipment for providing country cottages.

They can be operated in wells with a minimum cross section (internal diameter from 76 mm). It should be noted that the units of this manufacturer are quite sensitive to water quality. Durability and trouble-free operation are provided by various systems automatic protection(from dry running, overheating, power surges and others).

None of the owners of Grundfos SQ pumps regretted purchasing these particular devices.

The impellers are made of special thermal plastic resistant to various aggressive media. It is distinguished by reliability and unpretentiousness, the cost of the unit reaches 22 thousand rubles, which is quite inexpensive for equipment of this class.

The choice of pumping equipment is quite wide, so choose the best model for various conditions operation is simple.

If you do not have experience in this matter, then you should contact a specialist who can evaluate all the features of your well. In this case, the pump will last a long time and trouble-free.

If you decide to equip your own intake source(well) and at the same time they drilled it into the first aquifer (and these are, as a rule, wells into sand), then you will have to think carefully about choosing a pump. Since pumping water contaminated with sand is not within the power of every unit. Even the smallest grains of sand from the bottom of the source, accidentally falling into the pump, can disable it forever. And standard flushing of equipment will not help here.

What types of pumps will be best for a sand source and how to choose the right device, we understand below.

In order to understand the purpose for which a pump for a source of this type is so carefully selected, it is not superfluous, but even better, to know its device. So, the aquifer in this case is a sand deposit. And since the porosity of the sand is quite high, the mobility of the sand grains is also great. That is, during the movement of water in the reservoir and when it enters the well, as well as under the influence of a forced device (in our case deep pump) the sand will rise and fall into the pumped water. Thus, the supply of dirty water to the water supply system is not ruled out.

But this is not the biggest problem. Much worse is the fact that the motor of a pump pumping dirty water with sand simply cannot withstand such loads. long time, and burn. In this case, the deep unit is not subject to repair. Now weigh: are you ready to pay a tidy sum again for a new pump and at the same time know that the cause of the breakdown of an expensive device was negligence when choosing a pump?

Important: in order to ensure additional protection water and pumping equipment from sand, professionals in the arrangement of the bottom hole form a natural filter from fine gravel and pebbles. This allows you to stop the washing and movement of sand in the well. Here, a strainer is mounted at the end of the casing pipe.

vibration pump

The use of this type of submersible equipment for sand wells is highly discouraged. Firstly, the device itself, according to its technical indicators, does not accept the processing of dirty water.

And, secondly, the oscillatory movements of the pump in the well will simply create ideal conditions for the movement of grains of sand in water. In addition, there is a risk of partial or complete sanding of the well, which will require its thorough flushing and pumping with the help of professionals.

Surface pump

Although this type of unit is suitable for working in shallow wells (up to 8-9 meters deep), it cannot process dirty water. Even the smallest percentage of inclusion of sand in water can disable the unit once and for all. Moreover, this sensitivity to various components in water is inherent in both a vortex and a centrifugal unit.

Important: surface pumps- ideal solution for small suburban area and wells (wells) with a low flow rate.

Benefits of a centrifugal pump

The ideal solution for a sand well is a submersible centrifugal pump. Its ability to pump water with inclusions of sand, silt or clay allows you to be calm for the unit.

A distinctive feature of such submersible unit is its ability to pump dirty water with sand and other small inclusions. So, for some centrifugal-type models, the following indicators are relevant:

• Submersible pump "Vodomet" from the manufacturer "Dzhileks" - 150 g / m3;
• Deep pump "Aquarius" from the same manufacturer - from 150 g / m3 and above.

Moreover, user reviews indicate that such models of pumps successfully pump dirty water with the inclusion of sand in it up to 1.5 kg / m3.

Important: and yet you should not experiment and let the equipment wear out. It is better to ensure reliable bottomhole filtration before installing the pump.

Advantages of screw pump

Another type of quality pumping equipment for pumping dirty water. Such a unit works on the principle of the Archimedes screw familiar to everyone (a similar screw is installed in all models of meat grinders).

It is known that the ability of a screw submersible pump to pump sand sometimes led to the fact that rather long “sausages” of clay and sand rose from the bottom of the well. And manufacturers of such equipment guarantee that the pump can pump water with a sand content of up to 2 kg / m3.

It is noteworthy that screw-type submersible pumps can be mounted both in shallow wells and at a fairly large depth (up to 300 meters). In this case, the performance of the unit will be constant.

And one more thing: if you doubt the correctness of your choice and do not know which unit is better to buy, then consult with professionals. Since before buying a pump (surface or submersible), in any case, you need to know such parameters as:

• Average daily volume of water consumed per family (house);
