Which pump to choose for a well with sand. How to choose a borehole pump for dirty water. How a screw well pump works

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 large enough, 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 downhole 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 water passes through the motor, which consists of a rotor freely rotating 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.

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 hermetic sealing of the joint 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 the bottom filter, otherwise vibrations can lead to mechanical damage to the equipment or the structure 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 of proper installation and operation, 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.

Autonomous water supply has become a dream for many residents in the Russian Federation.

This is especially true for owners and land plots.

The reason is also in the constant deterioration of the quality of carriers on central highways.

Then from the very beginning it is necessary to decide on the choice of such a device as a borehole pump for dirty water.

Dirty water well pumps have found application in different areas life:

  • Filling containers in fire fighting systems.
  • For those who extract thermal water.
  • Provision of construction and industrial facilities.
  • Supply of fountains.
  • When irrigating crops.
  • For the needs of drinking and households.

Submersible pumps. About their varieties

  • Vibration pump deep for dirty water. are considered one-stop solution. Used for watering suburban areas. Differ in simple service, small dimensions.
  • Screw pumps. They work even if impurities are contained in the amount of forty g / m3. Able to function at a depth of up to fifteen meters, form a pressure of 90 meters.
  • For vortex models, the maximum possible amount of sand is the same 40 grams per cubic meter. But the depth of operation is increased to 30 meters. The pump inside consists of a special wheel. The water supply is based on the swirling principle. Such devices create a high pressure indicator, although they weigh very little.
  • The centrifugal type models differ in power. They are capable of lifting water from a depth of up to 200 meters. The pressure exceeds a hundred meters. The presence of built-in thermal protection is an additional feature.

Features of the choice of borehole pumps

First, the buyer is determined with the parameters that must have. After that, there will be very little to do. Here are some examples:

  • 3-4 people live in the object. They consume 1.2-1.6 cubic meters of fluid per hour.
  • We were engaged in the construction of a hydraulic tank, with a 100-liter capacity. In the on state, pressure up to 2 atm should be maintained, and in the off state - 3.5.
  • The distance from the house to the well is 15 meters.
  • 20 meters is equal to the dynamic level.
  • The performance indicator is up to three cubic meters per hour.
  • The borehole diameter or casing pipes differ in size of 133 meters.
  • Finally, a well was dug to a depth of 50 meters.

We can easily fit pumps with 3-4 inches, if you look at the borehole dimensions. Only after that we calculate the performance we need.

First you need to find out what height of water rise in the well we need:

  • 20 meters or 2 atmospheres is an indicator of the dynamic level.
  • 0.15 atmospheres or 15 meters - the distance between the house and the well.
  • There is a 3.5-atmospheric pressure index when two conditions are simultaneously met: the pump is turned on plus running out of water in the GA accumulator.

It is necessary to add the values ​​​​that we received: 2 + 0.15 + 3.5 \u003d 5.65 atmospheres. If you translate them into meters, it will be 57. This is the minimum level of pressure that is required in these specific conditions.

But it is necessary to take a closer look at the performance in the pipeline and pressure losses. Sometimes these indicators can be quite a lot.

Especially if the diameters of the outlet of the pipeline and the ones responsible for transporting the liquid do not coincide with each other. About 10-20 percent are usually losses on fittings and pipes.

How to decide on a brand

Rapid failure becomes the performance of equipment at a low level of quality.

It is best to trust manufacturers whose reputation is beyond doubt.

Here are just a few brands that have already earned the recognition of buyers around the world.

  • Russian Belamos.
  • Water Technics from Taiwan
  • Lowara from Italy.
  • Pedrollo from Italy.
  • Grundfos from Denmark.

A separate discussion deserves a series of pumps SQE, released by the manufacturer Grundfos. The main difference from analogues is the presence of the so-called frequency converter. Thanks to this detail, the likelihood of water hammer is reduced.

Starting currents remain not as high as usual. There is an electronic unit responsible for remote control.

It would be best to contact a company that has a license to provide the relevant services. But there are always moments that deserve special attention.

  • How smaller diameter device, the better. Then the probability of jamming will be much less.
  • The installation of pumps is carried out 1 meter below the place where the dynamic water level is located.
  • Well heads with water supply pipes should be below the level at which the soil begins to freeze. For this, the head is placed in a caisson. Instead, you can use an adapter, this device has a more affordable price.
  • The length of the cable and the power of the pumps determine the cross section that the power cable must have.
  • With plastic clamps, the cable is attached to the HDPE pipe, this is done every 3-5 meters.
  • Two cables are recommended to be connected using a heat shrink type sleeve.
  • Only a stainless cable can play the role of a safety structure.

There are certain rules along with requirements, the observance of which ensures uninterrupted operation for a long time. For example, water for these devices is not only a working fluid, but also a coolant. Pumps generally cannot work properly without water.

The liquid level sensor will help to avoid the so-called "dry mode" of operation. Thanks to this sensor, the power supply is turned off if the water level drops below critical levels.

Literally all parts of the device must be made of stainless steel. The cost in this case will be higher than that of analogues from others, but the costs pay off.

  • Stainless steel parts have no effect on taste qualities water, its composition.
  • When oxidized, such structures are not destroyed.
  • Because of what the cable does not break, and the pump does not fail ahead of time.

What causes borehole pumps to fail?

Most users are accustomed to the designation of only indirect signs for breakdowns.

These may include high electricity consumption, vibrations with interruptions in water supply, high noise levels, reduction, and so on.

The main thing is not to lead to a serious accident, to start acting when even the slightest signs appear.

The pump must be immediately lifted to the surface in order to carry out a thorough inspection.

Fine suspended particles, together with water, have the most serious effect on the pump.

It is possible to have various:

  • After that, the sensors stop working correctly.
  • Support too high temperature pumped water.
  • Incorrect fixation at the steel safety cable on the head.
  • Power and supply circuits operate with poor signals.
  • An unprotected pump is adversely affected by high voltage surges that occur too often.
  • Approximation of the dynamic level to the mark of a critical nature. Because of this, parts rub against each other more. Overheating of nodes that rotate appears. The power consumption is growing. Finally, the level of resistance rises.
  • The housing is broken tightness, which leads to the penetration of moisture inside. Because of what there are failures in working electronics. The operation of the entire device is disrupted. A possible result, if inactive, is the appearance of short circuits.
  • Fibers together with abrasive particles have a negative effect.

In any case, the pump must be raised to the surface. But one can only study indirect signs, and follow the path of exclusion. It is required to carefully inspect each of the parts in stock.

In the same way, the electric motor is checked. Be sure to check the power supply.

Troubleshooting the pump

Situations with a decrease in the dynamic level inside the device cannot be attributed to the group of serious breakdowns. But this situation has a direct impact on the performance of the device.

The pump quickly fails if it runs in a "dry mode". If this is what caused the problem, the pump is first lowered to a depth recognized as safe.

The valve is one of the parts operating in the mode of constant wear. It must be changed if water flows through the device, where there is too much sand.

Clamps with stainless steel cable are the perfect solution for any system. The electrical cable is responsible for the flow of electricity.

A good pump is a device with difficulties not only in technical terms. He also has other whims.

The most stringent requirements relate to the electricity network, stable operation. Plus or minus ten percent is the tolerance for most classic pumping stations.

In the case of submersible pumps, a deviation of 5 percent is allowed. It is better to put voltage stabilizers, then the supply voltage will flow without interruption.

Choosing the right pumps requires careful calculation, but it's not as difficult as it sounds.

How to distinguish a pump for dirty water from a drainage one is presented in the video:

Negative consequences of well pollution during operation

In the vast majority, not only after drilling, but also during operation or after a long downtime, pumping a well is most often necessary for sandy species. The bottom of their aquifer usually consists of sand, clay or pebbles, silting leads to the following negative consequences:

Reducing the depth of the water source

It may have Negative consequences for submersible electric pumps located at a short distance from the bottom, the filters and components of the working mechanism supplying water will begin to clog with dirt, which will lead to an accelerated failure of pumping equipment.

Water quality is deteriorating

In addition to the fact that the silted bottom approaches the water-sucking units, the rising water, passing through the silted layer, carries along small particles of dirt, which contribute to the turbidity of the liquid. Water becomes unfit for drinking and domestic use, and it becomes too expensive to clean it with filters.

Debit is falling

The water pressure is prevented by a layer of dirt formed during the silting process, which resists its passage. Water may simply not be enough for domestic needs if the pump pumps out all the water from the well.

The water level is dropping

A drop in static and dynamic levels is a consequence of a change in flow rate and can lead to dry running of operating electric pumps.

These negative consequences do not appear immediately and serve as signs indicating the need to pump the well source.

Requirements for electric priming pumps

Not every electric pump pumps out contaminated water, for example, the answer to the question - “is it possible to clean the well with vortex views?” will be negative. Vortex models in effect design features(small gaps between the impeller of the vortex wheel and the walls of the working chamber) are absolutely not intended for working with contaminated water. When choosing the right pumping equipment, the following criteria should be followed:

Well Compliance

A pump for pumping a well must be suitable for its parameters, primarily due to its pressure and immersion depth.

Water Quality Compliance

The polluted bottom of well sources may consist of various fractions: sand, clay or pebbles. The type of pumping device must be suitable for the structure of pollution, otherwise its operation in an unsuitable environment will be inefficient and lead to failure.

low cost

It is irrational to spend a lot of money in everyday life to buy an expensive pumping electric pump - when working in a polluted environment, the mechanism of any device wears out faster, and replacing parts in expensive equipment, in addition to its high cost, will lead to even greater costs.

This statement does not apply to organizations involved in the pumping of wells on professional level. For example, expensive high-quality Gundfos submersible electric pumps, due to their high reliability after many years of operation, are more profitable to pump wells than domestic models.

High performance

This parameter affects the pumping time of contaminated water, which in some cases can take more than a day, and the cleaning efficiency. More powerful models suck up liquid from greater depths, respectively, taking away more contaminants than low-power devices.

The main types of electric pumps for cleaning wells

Due to their design features, several types of electric pumps most commonly used in everyday life can work effectively with contaminated water.

Vibrating

The use of vibration types for pumping dirty water has the following advantages and disadvantages:

low cost. All vibration models belong to products of the budget price category, the minimum cost of the Aquarius pump is about 20 USD.

Simplicity of design. Allows you to repair or replace worn parts without much effort and special equipment.

Work with dirty water . Vibratory electric pumps are best suited for pumping clay contaminants, sand and small pebbles quickly erase their rubber parts.

Principle of operation. The use of vibration pumps adversely affects the casing pipes, causing their deformation, and can also lead to complete silting of the well source due to the compaction of the sedimentary layer during vibration.

Low performance and uptime. These are the main disadvantages of vibration pumps, excluding their use for permanent water supply.

Screw (screw) submersible electric pumps

Screw electric pumps have the following distinctive features:

High price. The cheapest Unipump ECO VINT1 models are 4 times more expensive than vibration models - about 80 USD.

Working with contaminated liquids. The devices work well with very viscous clay soils, sand and small stones wear out the screw.

Simplicity of design. Single screw household screw pumps have a simple device that allows you to independently clean, repair and replace parts without special skills.

Centrifugal pumps

Centrifugal types are the most common; both surface and submersible types are used to take pumped water from wells, which have the following features:

High price. Centrifugal electric pumps are quite expensive, the price of the cheapest Whirlwind models is 70 USD.

Working environment type. Special submersible centrifugal electric pumps are designed to work with fine solids - this allows them to pump water with sand.

Performance. Centrifugal electric pumps have a high efficiency and pumping volume, they can lift water to the highest height of all types presented.

For efficient pumping of wells, centrifugal electric pumps are most often used, designed to work with large particle sizes. Vibrating types are best used as auxiliary equipment for supplying water under pressure to the bottom of the well, causing mud to rise and mix.

How does a sand well work?

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 methodology additional protection 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 more efficiency at the end casing pipe mounted 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.

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, it enters the well and acts submersible pump, then the sand rises and enters the already pumped water. Because of this, it is possible to supply dirty water from the water supply.

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 better to choose, then seek help from a specialist who can give good advice and advise in such a 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 drill wells and equip them make a natural filter from fine gravel and pebbles. This stops the movement of sand in the well itself. A strainer is also attached to the end of the casing pipe.

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 often used for summer cottages, wells or wells with little depth.

Centrifugal pump

This type of pump is the ideal solution for a sand well. 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 is not afraid of strong 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.

Mud (or drainage) pumps high pressure must be present in the arsenal of any owner of suburban housing or a summer resident using autonomous water supply and sewerage systems. Such pumps, which belong to the category of drainage, are indispensable in cases where it becomes necessary to clean a silted well, pump out water and sludge from an overflowing septic tank or drainage pit, removing accumulated water from the plot, from the basement or cellar of the house.

Unlike conventional liquid pumping devices, the mud pump is specifically designed to handle liquids that contain sand, silt and other insoluble matter. For the manufacture of high-pressure mud pumps that can withstand increased loads, especially strong and wear-resistant materials are used.

Principle of operation and scope

By its design, the mud pump is a single unit consisting of an engine and a working mechanism placed in a common housing. Between motor and working mechanism mud pump high-pressure oil chamber and a block of sealing elements are located. A conventional submersible pump has a multi-channel design, while mud pumps have only one channel through which the contaminated liquid medium is pumped.

Household models of submersible mud pumps, as a rule, have a power of 1.5–1.75 kW; they can be used to pump contaminated liquid from wells, the depth of which reaches 60 meters. The density of the liquid pumped by such high-pressure pumps should be 1.1–1.2 kgf / cm 3, and the amount of impurities in it should reach 10%. The size of insoluble inclusions contained in the liquid pumped by domestic models of high-pressure mud pumps can reach up to 5-10 mm, and imported - up to 50 mm. During operation, the mud pump must be cooled, which is ensured by the liquid surrounding it. A special filter is installed on the suction pipe of the high-pressure mud pump, which limits the particle size of insoluble impurities contained in the pumped liquid.

Depending on the design submersible mud pumps can be rotary or vibrating. Main working element rotary pumps is an impeller with blades rotating on the rotor shaft inside the device housing. In vibration pumps, the role of such an element is played by a steel membrane, which vibrates under the action of alternating current and thereby creating rarefaction of air in the working chamber. Vibratory pumps, although they are characterized by lower power when compared with rotary devices, are characterized by higher reliability and a longer service life, since there are no rubbing parts in their design.

Among the high-pressure mud pumps, semi-submersible devices should be distinguished, designed to pump a medium with a density of 1.3–1.5 kgf / cm 3. Such mud pumps, the working part of which can be made of corundum steel, ebonite or rubber, can operate at a temperature not exceeding 60 °.

For pumping media with more than high density, as well as media containing inclusions with a fibrous structure (fabrics, algae, etc.), mud pumping devices of another type are specially designed - fecal. In the design of such pumps, the inlet and outlet pipes of which are distinguished by expanded diameters, there is a special impeller that cuts fibrous inclusions into smaller fractions.

The most common applications for high pressure mud pumps are:

  1. pumping out used dirty water during construction works and service production processes(pumping out sludge water, etc.);
  2. level down ground water after heavy rainfall, floods or flood situations;
  3. pumping water and sludge from basements, cellars, gutters and pools;
  4. cleaning of wells, replacement of polluted water in artificial reservoirs;
  5. organization of watering of green spaces growing on personal plots.

Advantages and disadvantages

The mud pump, the design of which is specially designed for pumping liquid media containing a significant amount of insoluble impurities, has a whole list of advantages:

  • high mobility (this makes it easy to carry and use the drainage pump in those places where it is needed at the moment);
  • high power, allowing the use of a mud pump for pumping liquid media from great depths;
  • anti-corrosion properties of the body;
  • a special design, which is designed in such a way that even in the cold season, the parts that make up the submersible pump do not freeze;
  • low noise during operation.

Of course, like any technical device, a high-pressure mud pump has its drawbacks.

  • The body of such a device is non-separable, so it is almost impossible to repair a submersible pump if it is out of order, it can only be replaced with a new one.
  • Since the submersible pump is constantly in a liquid medium during operation, quite serious requirements are imposed on its electrical safety.

In addition to submersible mud pumps, modern manufacturers offer models of pumping equipment surface type, which are installed on the surface of the earth, and only a hose or pipe connected to the suction pipe of the device is immersed in the pumped liquid medium. If we talk about the advantages that distinguish a self-priming mud pump of a surface type, then they should include:

  • a fairly low cost when comparing such a pump with submersible models;
  • ease of installation and Maintenance;
  • high electrical safety.

Meanwhile, surface-type mud pumping devices can be used only in cases where water containing dirt and other insoluble inclusions in its composition needs to be pumped out from a shallow depth - no more than 8–10 meters. Another significant disadvantage of high-pressure surface mud pumps is that such devices emit quite a lot of noise during their operation.

When choosing a pump for cleaning a well or for solving any other problems associated with pumping contaminated liquid media, one should take into account not only the depth of the source from which such a medium will be pumped out, but also the distance over which it will be transported in a horizontal direction, as well as the degree of its pollution and the size of the inclusions contained in its composition.

Labeling rules

When designating a model of pumping equipment, which today is produced by many domestic and foreign companies, manufacturers do not adhere to uniform rules and regulatory requirements, but a certain regularity in this matter can be traced. So, in the marking of many models of such equipment there are both alphabetic and numeric characters. The letter part of the mud pump marking usually contains the following information about the equipment:

  1. pump type;
  2. speed factor.

The digital part of the marking indicates the diameter of the inlet pipe in mm.
The labeling of faecal mud pumps contains the following information:

  • SM - waste-mass type device;
  • XX is the diameter of the suction pipe;
  • XX is the diameter of the discharge pipe.

On many models of high-pressure drainage pumps, you can find this type of marking - XXX / X FN, which is deciphered as follows:

  • XXX - the volume of supply in liters, which the pump is able to provide per unit of time (min);
  • X is the pressure of the liquid, measured in meters;
  • Ф - type of pump (fecal);
  • H - body material (stainless steel).

The marking of pumping equipment may also contain other information (in particular, the presence of automation).

Using a drain pump to clean a well

Cleaning the well with a drainage pump is a fairly common procedure, the regular implementation of which allows you to always get well water that is not contaminated with sand, silt and other foreign matter. Some owners of dachas and country houses, in whose household territories there is a source, acting in the old fashioned way, clean it manually, using a brush and a bucket on a rope for this purpose. Meanwhile, without using a cleaning pump in combination with this method, it will be quite difficult to solve the problem. In practice, in order to effectively purify well water, they try to use both methods: first, using mechanical means, they clean the walls of the shaft, and then, using a high-pressure mud pump, they clean the water-bearing lens.

To understand why well cleaning requires such a comprehensive approach, it is necessary to understand what can cause water pollution in a natural water supply. So, the most common factors affecting the pollution of well water are:

  1. the quality of the soil in which the source is equipped;
  2. operating conditions of a hydraulic structure, the reliability of protecting its water layer from sunlight, which is the cause of the development of flora (blue-green algae) and fauna (bacteria and microorganisms);
  3. quality of arrangement clay castle and its tightness
  4. reliability of protection of the water layer from sewage and untreated water from nearby reservoirs.

The following signs indicate that the well urgently needs high-quality cleaning.
