Deep Well Pumps: Best Models + Equipment Selection Tips

Well pumping stations

BELAMOS TF3-60

Pumping stations provide water supply without the use of physical force. This requires a preliminary scheme, the presence of electricity and compliance with the sequence of connecting the pumping station.

Mounting on the surface of the earth is the advantage of the pumping station. A thin hose with a check valve is lowered into the well.The station provides pressure up to 1.5 atmospheres, which is enough to supply water to a two-story house.

Disadvantage: installation in a warm room and regular maintenance.

Connecting the station to the well is possible with your own hands.

How to install and how to connect the pump correctly?

First, let's deal with the main characteristics of the pump for the well:

• power;
• performance;
• the volume of the tank for storing a reserve supply of drinking water;
• the height of the water level from which its intake is possible;
• materials from which the pump and accumulator housing are made;
• protection against possible overheating and dry running;
• control methods (manual or remote);
• check valve;
• input filter.

Pipes from the well to the pump housing are laid in a trench, below the level of soil freezing. The well or well is insulated and well closed.

Surface are oriented to work with shallow depths, because their
installed above the well.

Deep with high power or household stations with a submersible pump are used for wells up to 50, 80, 100 m.

The best submersible pumps for a well

As the name suggests, these pumps are designed to be fully or partially submerged in water. Among them, well and borehole models are distinguished. Depending on the type chosen, the height of the water column varies from 9 to 200 m. Submersible pumps are characterized by high efficiency (compared to surface models) and the presence of a sealed casing.

Usually they are equipped with a filter and automatic protection against dry running.

Experts also recommend paying attention to the presence of a float that will turn off the power to the pump when a critical water level is reached.

Best well pumps: CHIP version

VORTEX CH-90V

Domestic pump (assembled in China) for wells with a maximum depth of immersion in water up to 35 m. It allows you to raise water to a height of up to 90 m, which is quite enough to provide water to a two-story house. At the same time, it produces an average of up to 1500 l / h - this is enough for a house with a toilet, washbasin, washing machine and shower. True, the power cord here is only 17 m, so you have to use an extension cord.

The device has a single-stage design with one rotation wheel. Please note that the impeller is made of stainless steel, so it is not subject to corrosion. This is a simple and inexpensive pump for the home. If you don't want to overpay, then take it.

Note that in the SN series, Vikhr has 8 more models with a maximum head from 50 to 135 m and a capacity from 1500 l / h to 5700 l / h. If the VORTEX CH-90V does not suit you in terms of parameters, then you can choose another one from the same company.

BELAMOST TF-25

This pump is perfect for a one-story house with several points of water intake. The maximum device is able to pump out up to 4000 l / h, which is quite enough for simultaneous dishwasher operation, boiler, washing machine and shower. In this case, the pressure in the pipeline system will be maintained at a good level. The maximum pressure is 28 m - for a shallow well, "the very thing."

JILEX Water cannon PROF 55/75

One of the most popular Russian-made models in the segment up to 10,000 rubles.It is capable of pumping 3300 l / h with a head of 75 m, which is enough for two to three floors or for the simultaneous operation of several consumers. Its maximum immersion in water is 30 m. There is a thermal switch here that turns off the device in case of overheating.

Note that there is a really long power cord of 30 m, which most models in this price category simply do not have. It is also capable of pumping water with a maximum solid particle diameter of up to 1.5 mm, so it is suitable for “fresh” wells that are heavily sanded. True, so that dirty water does not enter the water supply system, we recommend installing filters at the inlet.

Termica Comfortline 3SQ 3/90

One of the best pumps with a depth of immersion in water up to 80 m. When immersed to such a depth, the device is capable of delivering pressure up to 91 m. Thanks to these indicators, the unit has gained popularity among those who live on a hill who have water very far away and have to hit a deep well. In terms of performance, the device has an average performance of 2700 l / h.

The impeller is made of noryl, a polymer material that is highly resistant to corrosion. In addition, it is resistant to solid particles in the form of sand up to 1.5 mm in size. There is also a 40m long power cord.

Aquarius BTsPE 0.5-63U

A powerful 1200-watt beast is capable of pumping water with a maximum head of 90 m. At the same time, the density of solid particles in water can be up to 1500 g / m3 and the pump will not fail. This makes the model in demand for pumping water from dirty or sandy wells. A multi-stage suction system is installed here, consisting of several wheels.

The maximum productivity is 3600 l / h - the average for devices with such power. Many are sure that the pumps are assembled from Chinese components, but in fact, a full production cycle has been established in Kharkov, so the components are also their own. Users note the high build quality and long life of the device.

Selection Options

Well pumps are easy to distinguish even by their appearance. They are an elongated cylinder made of stainless steel or plastic. Naturally, stainless steel models are more expensive - the steel must be of high quality (usually food grade AISI304). Pumps in a plastic case are much cheaper. Although they are made of a special impact-resistant plastic, they must be handled with care - it still does not tolerate shock loads very well. All other parameters will have to be selected.

Brief technical characteristics of the pump for the well

Water flow and pump performance

In order for the water in the house or in the country to be with sufficient pressure, equipment is needed that can deliver the required volume of liquid. This parameter is called pump performance, measured in liters or milliliters (grams) per unit of time:

• ml/s - milliliters per second;
• l / min - liters per minute;
• l / h or cubic / h (m3 / h) - liters or cubic meters per hour (one cubic meter is equal to 1000 liters).

Borehole pumps can lift from 20 liters/min to 200 liters/min. The more productive the unit, the greater the power consumption and the higher the price. Therefore, we choose this parameter with a reasonable margin.

One of the key parameters for selecting a well pump is performance

The required amount of water is calculated by two methods. The first takes into account the number of people living and the total expense. If four people live in the house, then the water consumption per day will be at the rate of 800 liters (200 l / person). If there is not only water supply from the well, but also irrigation, then some more moisture must be added. We divide the total amount by 12 (not by 24 hours, because at night we use water supply to a minimum). We get how much we will spend on average per hour. Dividing it by 60, we get the required pump performance.

For example, for a family of four and watering a small garden, it takes 1,500 liters per day. Divide by 12, we get 125 liters / hour. In a minute it will be 2.08 l / min. If you often have guests, you may need a little more water, so we can increase the consumption by about 20%. Then you will need to look for a pump with a capacity of about 2.2-2.3 liters per minute.

Lifting height (pressure)

When choosing a pump for a well, you will inevitably study the technical specifications. There are parameters such as lifting height and immersion depth. Lifting height - also called pressure - is a calculated value. It takes into account the depth from which the pump will pump water, the height to which it must be raised in the house, the length of the horizontal section and the resistance of the pipes. Calculated according to the formula:

The formula for calculating the pump head

An example of calculating the required pressure. Let it be necessary to raise water from a depth (pump installation site) of 35 meters. The horizontal section is 25 meters, which equates to 2.5 meters of elevation. The house is two-story, the highest point is a shower on the second floor at a height of 4.5 m. Now we consider: 35 m + 2.5 m + 4.5 m = 42 m.This figure is multiplied by the correction factor: 42 * 1.1 5 = 48.3 m. That is, the minimum pressure or lifting height is 50 meters.

If there is a hydraulic accumulator in the water supply system of the house, it is not the distance to the highest point that is taken into account, but its resistance. It depends on the pressure in the tank. One atmosphere is equal to 10 meters of pressure. That is, if the pressure in the GA is 2 atm, when calculating, instead of the height of the house, substitute 20 m.

Immersion depth

Another important parameter in the technical specifications is the immersion depth. This is the amount with which the pump can pump out water. It varies from 8-10 m for very low-power models to 200 m and more. That is, when choosing a pump for a well, you need to look at both characteristics at once.

For different wells, the depth of immersion is different

How to determine how deep to lower the pump? This figure should be in the passport for the well. It depends on the total depth of the well, its size (diameter) and flow rate (the rate at which water arrives). In general, the recommendations are as follows: the pump should be at least 15-20 meters below the water surface, but even lower is better. When the pump is turned on, the liquid level drops by 3-8 meters. The amount remaining above it is pumped out. If the pump is very productive, it pumps quickly, it must be lowered lower, otherwise it will often turn off due to lack of water.

Well diameter

An important role in the selection of equipment is played by the diameter of the well. Most domestic well pumps have sizes from 70 mm to 102 mm. In general, this parameter is usually measured in inches. If so, then the easiest way to find three and four inch specimens. The rest are made to order.

The well pump must fit in the casing

The best submersible pumps for a well

Submersible pumps for wells have high power and are able to pump water with high pressure. They will be useful where the water source lies deep underground - up to 300 meters. Such devices are most often installed after the preliminary drilling of the well. Separate powerful models are capable of pumping up to 80 cubic meters of water per hour. On average, a conventional borehole pump with a budget of up to $ 200 has a throughput of 1.7 - 3.4 cubic meters. m/hour. This capacity is sufficient to provide water to a private house with a kitchen, toilet and bathroom.

We suggest that you familiarize yourself with the rating (TOP-5) of the best submersible pumps for a well.

submersible pump rating

The rating includes the best submersible pumps that have passed a rigorous selection. All models received high quality ratings from experts, a large percentage of positive feedback from ordinary users. The selection took into account compliance with the following key parameters:

• Power;
• Performance;
• Water level control;
• lifting height;
• transfer distance;
• Max pressure;
• destination category;
• Rated weight;
• Installation method;
• Protection against overheating, dry running;
• body material;
• Functionality;
• Noise level;
• Working temperature.

Safety characteristics, cost, warranty period were also taken into account. The pros and cons of each individual model were considered. As a result, the best nominees were divided into three application categories.

The best pumps to increase water pressure

Pump selection

Knowing the main characteristics, you can proceed to choosing a specific unit.

So, we have two quantities - resistance and performance. Let's return to our schedule with the head-flow characteristic.

We plot the resistance value on the Y axis, and the flow rate on the X axis. Then we select the unit, the graph of the pressure-flow dependence of which is located near this point:

It is necessary to choose such an apparatus, the operating point of which will be located as close as possible to the point we noted earlier.

Important! As a rule, the graph shows three lines for different modes of motor operation. It is best to be guided by the second speed, and the operating point should be located in the middle third of the diagram, since it corresponds to the highest efficiency.

The pump must match the pipe diameter.

Of course, it is necessary to select a device designed for high ambient temperatures (95 - 110 ° C), and also know the diameter of the pipe into which the device will be embedded. The price of the device will depend on the manufacturer and quality.

The correct choice of the circulation pump for the heating circuit is made on the basis of calculations. If the material presented seems too complicated for you, watch the video in the article.

Analysis of small nuances

The quality of drilling work is another point to consider when choosing a pump for a well. If drilling is performed using professional equipment and by a specialized team, such a well is considered more reliable.

If drilling was carried out by covens or site owners with the help of amateur friends, the quality of the well is unlikely to be ideal.

If the well is drilled professionally, it will be less likely to silt and sand, which will favorably affect the operation of pumping equipment.

“Amateur” wells, as practice has shown, are more prone to flooding and sanding. Therefore, for such wells, it is recommended to use special pumps designed to work in difficult conditions. This type of equipment is more expensive.

But it better tolerates situations when water with a lot of pollution enters them. Under the same loads, conventional pumps break much more often. Owners of “professional” wells have more options when choosing equipment, since they can choose from a universal or special pump.

It is not always convenient to use a rubber hose to lift water from the depth of the well to a height. During the operation of pumping equipment, the air inside the hose becomes rare, from this the walls of the hose collapse, and the flow of water stops. To prevent this phenomenon is simple: instead of a rubber hose, plastic structures of a suitable diameter should be used.

A pressure-rated water supply pipe is more effective downhole than a rubber hose that can collapse, obstructing the water supply

An important indicator when choosing a pump is the approximate water consumption for one day. This is an average value, since water consumption usually increases in summer, and, on the contrary, decreases in winter. It is believed that the daily intake for a family of three to four people is approximately 60-70 liters.

These figures do not take into account water consumption for irrigation and other household needs. The daily rate should be increased depending on the number of plants on the site, the presence of pets, etc.

Prudent owners most often choose four-inch casing pipes for the well, although designs with a diameter of three inches are also used in this capacity. The fact is that a significant part of the pumping equipment is designed specifically for a more spacious four-inch pipe.

To convert centimeters to inches, you should divide the result of measurements with a tape measure by 2.54, since one inch is equal to this number of centimeters.

In order to ensure that at all points of water intake there is sufficient pressure for operation, a hydraulic calculation is necessary. Its approximate version can be made using this table. All points must be adequately supplied with a pump

Deep well pump

For a deep well, deep well pumps are used, the installation is made directly inside the well below the water surface. Water can be sucked in from the bottom or from above.

Type / scope of use

Industrial	Used in enterprises, lifting water from a depth of up to 100 m and 120 m
household	They are used in summer cottages or in private houses, despite their compactness, they are endowed with great power.

Power is determined by pressure. Deep pumps with a capacity of 10 cubic meters are often used.

The design of the deep pump is simple. Models are of two types:

1. rod;
2. barless.

Rodless deep well pumps can be of three types by design:

1. vibration;
2. vortex;
3. centrifugal (multistage);
4. screw or worm (auger).

How deep should a well pump be installed?

Installation is carried out subject to the following tolerances:

• the device, lowered into the water reservoir, must have at least 1 m of water surface above it;
• The pump must not come into contact with the bottom of the well.

Screw pumps are highly efficient units, the functionality of which does not depend on either the positioning of the housing or the properties of the pumped medium.

Simply put, a screw pump can pump even very dirty liquids both horizontally and vertically. Screw pumps are used to lift water from wells with a depth of not more than 15 m.

Deep pumps are used at a depth of 20, 30, 40, 50 and 60 meters.

submersible pump rating

The rating includes the best submersible pumps that have passed a rigorous selection. All models received high quality ratings from experts, a large percentage of positive feedback from ordinary users. The selection took into account compliance with the following key parameters:

• Power;
• Performance;
