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

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

First of all, pay attention to the following characteristics:

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

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

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

This is especially true for owners and land plots.

The reason is the constant deterioration in the quality of media 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.

Subsurface pumps for dirty water have found application for different spheres life activity:

• Filling containers in fire protection 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

• Deep vibrating pump for dirty water. They are considered a universal solution. Used for watering on suburban areas... They are distinguished by simple maintenance, small dimensions.
• Screw pumps. They work even if the impurities are contained in an amount of forty g / m3. They are capable of functioning at a depth of up to one and a half dozen meters, and generate a head 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 has been increased to 30 meters. The pump inside consists of a special wheel. The water supply is based on the vortex principle. Such devices create a high rate of pressure, although they weigh very little.
• Centrifugal models differ in power. They are capable of lifting water from a depth of up to 200 meters. The head is over a hundred meters. Built-in thermal protection is an additional function.

Features of the choice of borehole pumps

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

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

Pumps with 3-4 '' fit easily if we look at the borehole dimensions. Only after that we calculate the required performance.

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

• 20 meters or 2 atmospheres is a dynamic level indicator.
• 0.15 atmospheres or 15 meters is the distance between the house and the well.
• There is a 3.5-atmospheric pressure indicator with the simultaneous fulfillment of two conditions: the pump is turned on plus the ending water in the HA accumulator.

It is necessary to add up the values ​​that we received: 2 + 0.15 + 3.5 = 5.65 atmospheres. If we 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 the pressure loss. 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. Around 10-20 percent are usually losses in fittings and pipes.

How to choose a brand

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

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

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

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

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

Inrush currents are 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.

• The smaller the diameter of the device, the better. Then the probability of jamming will be much less.
• The pumps are installed 1 meter below the place where the dynamic water level is located.
• The head of the well with water supply pipes must 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 is more affordable.
• The length of the cable and the power of the pumps determine the cross-section that the power cable must have.
• The cable is connected to the HDPE pipe with plastic clamps, this is done every 3-5 meters.
• It is recommended to connect the two cables using a heat-shrinkable sleeve.
• Only a stainless steel cable can act as a safety structure.

There is certain rules together with the requirements, compliance with which ensures smooth operation for a long time. For example, water for these devices is not only a working fluid, but also a coolant. Pumps cannot run normally without water at all.

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

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 are paid off.

• Stainless steel parts have no effect on taste qualities water, its composition.
• These structures are not destroyed during oxidation.
• Because of which the cable does not break, and the pump does not fail ahead of time.

What causes borehole pumps to break down

Most users are accustomed to designating only indirect signs for breakdowns.

These may include high electricity consumption, vibrations with interruptions in water supply, high noise levels, degradation, 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 lifted immediately to the surface for a thorough inspection.

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

The presence of various is acceptable:

• After that, the sensors stop working correctly.
• Maintaining too high a temperature of the pumped water.
• Incorrect fixing of the steel safety rope on the head.
• Feed and feed circuits are operating with bad signals.
• A pump without protection is adversely affected by high voltage surges that occur too often.
• Approaching the dynamic level to the critical mark. Because of this, the details rub against each other more. Overheating of the nodes that rotate appears. Electricity consumption is growing. Finally, the resistance level rises.
• The tightness of the case is broken, which leads to the penetration of moisture inside. Because of what failures occur in working electronics. The whole device is not working properly. 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 lifted to the surface. But you can only study indirect signs, and follow the path of exclusion. It is required to carefully examine each of the parts in stock.

The electric motor is checked in the same way. The power supply must be checked.

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 direct influence the operability of the device.

The pump breaks down quickly if it runs dry. If this is what caused the problem, the pump is first lowered to a depth deemed safe.

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

Clamping Clamps with Stainless Steel Rope - optimal solution for any system. The electrical cable is responsible for the flow of electricity.

A good pump is a device with complexities, 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 install voltage stabilizers, then the supply voltage will continue to flow without interruption.

Choosing the right pumps requires careful calculations, but it is not as difficult as it sounds.

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

Negative consequences of well contamination during operation

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

The depth of the intake source decreases

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

Deteriorating water quality

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

Debit falls

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

The water level is dropping

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

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

Requirements for electric pumps for circulation

Contaminated water is not pumped out with every electric pump, for example, the answer to the question - "Is it possible to clean a well with vortex types?" will be negative. Vortex patterns in force design features(small clearances between the vortex impeller and the walls working chamber) are absolutely not intended for work with contaminated water. When choosing suitable pumping equipment, the following criteria must be followed:

Well compliance

A pump for pumping a well must be suitable for its parameters, first of all, this is due to its head and immersion depth.

Compliance with water quality

The contaminated bottom of borehole sources can consist of various fractions: sand, clay or pebbles. A type pumping device must be suitable for the structure of pollution, otherwise its operation in an unsuitable environment will be ineffective 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 that pump wells on a professional level. For example, with expensive high-quality Gundfos submersible electric pumps, due to their high reliability after many years of operation, it is more profitable to pump wells than domestic models.

High performance

This parameter affects the time of pumping out contaminated water, which in some cases can take more than a day, and the efficiency of treatment. More powerful models suck in liquid from greater depths, respectively, taking 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 often used in everyday life, can work effectively with contaminated water.

Vibrating

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

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

Simplicity of design... Lets without special efforts and special equipment to repair or replace worn-out parts on their own.

Working with dirty water... Vibrating electric pumps are best suited for pumping clay dirt, sand and small pebbles quickly rub off their rubber parts.

Principle of operation... The use of vibration pumps negatively affects the casing, causing their deformation, and can also lead to complete siltation of the well source due to the compaction of the sediment layer during vibration.

Low productivity and uptime... These are the main disadvantages of vibration pumps, which exclude their use for constant water supply.

Screw (screw) submersible electric pumps

Screw electric pumps have the following distinctive features:

High price... The cheapest Unipump ECO VINT1 models cost 4 times more than vibration ones - about $ 80.

Working with contaminated liquids... The devices work well with very viscous clay dirt, sand and small stones erase 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; for the intake of pumped water from wells, both surface and submersible types are used, having the following features:

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

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

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

For efficient pumping of wells, centrifugal electric pumps are most often used, designed to work with a large particle size. 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 hole work?

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

The aquifer is represented by sandy deposits. The porosity of the material is large, therefore, the mobility of each grain of sand is also great. The sandy water flow puts additional stress on the pump. The device cannot pump dirty water for a long time, therefore it burns out quickly. It cannot be repaired. What to do in a similar situation? The reasons for the rapid failure of the 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 gravel or pebbles is used. This good way braking any washout or movement of sand throughout the well. For greater efficiency, a mesh type of filter is mounted at the end of the casing.

Unit description

The sand pump is a single stage and centrifugal equipment. The main task of such a design is to pump abrasive slurries, waters with various impurities. But a liquid for efficient pumping must have some properties.

The pumped solution must have:

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

The correct choice of pumping equipment for a well will determine its productivity, durability, and sometimes the operational life of the hydraulic structure itself.

MAIN TYPES OF PUMPS AND THEIR FEATURES

• Vibrating- they are more often used in wells, since, as a result of vibrations, they can not only raise sediment from the bottom, but also damage the walls of wells
• Centrifugal submersible- more than once convinced that this the best solution for wells. During operation, a minimum of vibrations is formed, the performance is quite high, 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 pump and equipment for the well, criteria

• Height of water rise- 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 highest point of the water intake from the 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 encountered in practice damage that vibration pumps can inflict on a PET pipe or downhole filter
• 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 it is better to use centrifugal (vortex) submersible pumps for wells, regardless of their depth, the material of the casing walls and the type of downhole filter.

Why?

During operation, they do not vibrate, therefore they do not lift sediment from the bottom, and most importantly, they are not capable of damaging the walls of the casing string and the bottom hole filter. They are also characterized by high performance, and unlike vibration pumps, they can run for longer in continuous operation.

Important!

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

What types of wells do we drill

Pros of centrifugal submersible pumps

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

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

Below I will review the performance of several centrifugal pumps versus a vibratory counterpart to help you understand the difference in performance.

Pump model	Power	Lifting height	Productivity l / hour	Immersion depth	Price
Vibration pump BELAMOS BV012, 25 m	300 watts	70 m	990 l	3m	2800 rubles
Centrifugal submersible pump Caliber NPTsS- 1.5 / 50-550	550 watts	50 m	1500 l	5 m	5300 rubles
Centrifugal submersible pump QUATTRO ELEMENTI Deep 1500 Pro 772-531	1500 watts	115 m	5460 l	2 m	19,500 rubles
Submersible borehole pump BELAMOS TF-60	900 watts	60 m	4000 l	5 m	15,000 rubles
GRUNDFOS SP 5A-25 3x400В 05001K25 with dry run protection	2200 Wt	153 m	6500 l	600 m	67,000 rubles
Dzhileks Vodomet PROF 55/75 House (set for automatic autonomous water supply)	900 watts	75 m	3300 l	30 m	26,000 rubles

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

Frequent mistakes when choosing and installing a pump

So what shouldn't you do?

• "The neighbors have this - it means that it will suit me as well"- a classic mistake. Two wells located 20-50 meters apart can vary greatly in production. In addition, it is important to consider factors such as material, casing diameter, type of bottomhole screen, consumption volumes.
• "I will buy more powerful - in reserve" Is another common misconception. First, why overpay? Secondly, a pump that is too efficient can ruin a well with a low flow rate by salvo pumping. We often had to repair a well, the quality of water in which was lost precisely because of the wrong choice of pump
• "I will do all the calculations myself"- even many of my colleagues, who have switched to free bread, do not always make calculations with high accuracy - too many factors and coefficients need to be taken into account. You better entrust it to professionals

Classic when installing pumping equipment yourself:

• Incorrect installation depth
• Improper attachment of the pump to the support cable, as a result of which part of the load falls on the power cord
• Incorrect connection to the mains

IMPORTANT!

Self-assembly - 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.

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 pump mounting depth is a constant value recommended by the equipment manufacturer. The nuances apply only to 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.

To 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 mud from the bottom of the hole. 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 lift 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 should remain to its bottom, as required by the instructions for the equipment.

Dry running protection for borehole pump

Imagine this situation - you are not at home, the 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 has protection against dry running - relays, special floats and automation, then such incidents are excluded.

Borehole pump conduit. well submersible pump cable extension

I can assure you that you will not find a pump that comes with an electric 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 do not categorically recommend doing this on your own, but if you nevertheless decided, then here are some of my professional advice:

• Use a submersible cable- yes, it is a little more expensive, yes - there will be no disaster if you take an ordinary cable, 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 should be at the maximum height from the water mirror - do not cut the cable just before entering the pump - cut the plug
• Use special connectors and epoxy for hermetically sealed joints or special heat shrink sleeves
• Use a cable of the correct size corrected for resistance in length

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

Pump and automation for a well for sand

Sand wells in the Moscow region are mainly used for irrigation in garden plots.

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

The optimal solution is a submersible vibration pump. It is affordable, not picky about water quality.

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 or the bottom filter, otherwise vibrations can lead to mechanical damage to the equipment or the structure itself.

We automate a system based on a vibration pump

The easiest option for automatically turning off such a pump is a timer switch.

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 take the required volume of water, and leave to go about your business.

A float system can also be used.

Low flow pump for a well with low flow rate

Wells with low flow rates are a serious problem. I have often come 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 flow rate of a well is 250 liters, then this is almost a twofold discrepancy.

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 maintain it at full
• We install automation to protect against dry running in the well

What do we get as a result? Your country house is provided with water, since 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 machine wash in an automatic machine is 60-80 liters, toilet cistern- 8-15 liters.

The pump works in sections for 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 the vibration pump harmful to the 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 pump is irrelevant, and in these cases it is important to at least observe the installation rules:

• Install the vibrating 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 - so it will less disturb the bottom

Water hammer when turning on the pump and strong shock when turning 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 wedged directly into the system.

Avoiding this is simple - for this, I advise you to definitely use membrane accumulators. They dampen pressure surges in the system, extending the life of your expensive plumbing fixtures.

Features of servicing pumping equipment

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

When using centrifugal submersible pumps for pumping water with sand impurities, repairs may be required - replacing the vane disks. All these works should be carried out only by a professional - you can only harm yourself.

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

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

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

In order to understand why the pump is so carefully selected for a source of this type, it is not superfluous, and even better, to find out its device. So, the aquifer in this case is sand deposits. And since the porosity of the sand is high enough, the mobility of the grains of sand is also great. That is, when water moves in the reservoir and when it enters the well, as well as when a forced device (in our case, a deep pump) is applied, the sand will rise and enter the pumped water. Thus, the supply of dirty water to the water supply system is not excluded.

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

Important: in order to provide additional protection of water and pumping equipment from sand, professionals, when arranging the bottom of a well, form a natural filter from small-fraction crushed stone and pebbles. This allows you to stop washing and sand movement in the well. Here, a mesh filter is mounted at the end of the casing.

Vibrating pump

It is highly discouraged to use this type of downhole equipment for sand wells. Firstly, the device itself, according to its technical parameters, 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 the water. In addition, there is a risk of partial or complete sanding of the well, which will require 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 sand included in the water can disable the unit once and for all. Moreover, a similar sensitivity to various components in water is inherent in both a vortex unit and a centrifugal one.

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

Centrifugal pump advantages

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

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

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

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

Important: nevertheless, it is not worth experimenting and letting the equipment wear out. It is better to ensure reliable bottomhole filtration before installing the pump.

Progressing Cavity Pump Advantages

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

It is known that the ability of the 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 the manufacturers of such equipment guarantee that the pump can pump water with a sand content of up to 2kg / m3.

It is noteworthy that screw-type submersible pumps can be installed 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);
• Well depth;
• Source casing diameter;
• Well flow rate.

Only in this case you will be able to choose the most optimal pump model for your sand well.
