10 best submersible pumps for wells from 15 to 100 meters

The ruler works with different productivity ― from 1600 to 6000 l/h. The pumps are equipped with a power of 500-2000 W and create a pressure of 7 to 15 atm. The pressure range of 60-150 m allows you to choose a submersible model for both irrigation and water supply of a large private house with 2-3 floors. For the entire series, the German company provides a 3-year warranty - which is not bad, given the affordable cost and Chinese assembly. Commissioning is very simple - I lowered the pump into the well and can be turned on without first filling with water. The manufacturer has provided thermal protection that extends the life of the electric motor during prolonged use.But the cable of 20 m does not correspond to the maximum working depth.

Quiet centrifugal pumps of the ASP series are suitable for houses in which a well is drilled right inside (in a boiler room, bathroom, etc.). The oil-filled engine runs silently and will not disturb vacationers if the automation starts it at night. Inside the case there is a built-in protection unit with a thermal switch and a starting device. There are no boxes outside. Previously, pumps were produced with a cast-iron outlet pipe, which gradually rusted and fell off. Now the manufacturer has replaced it with an alloyed one, like the more expensive brands. Judging by the reviews, ASP series products work smoothly for up to 8 years. The series is divided by color - models made of shiny stainless steel are allowed to be immersed to a depth of up to 50 m, and black pumps - up to 100-150 m. The units create a pressure of 60-150 m and pump 2700-4800 liters per hour.

Pumps of the ECO VINT series are designed for immersion of 12, 17 and 27 m. When the well dries up in the summer and does not have time to fill up, the unit has enough depth of 50 cm to the water table to work smoothly. If the channel becomes very shallow, the pump will drive air - there is no protection against dry running. The working group will need to be replaced. Its cost is from 800 rubles, which is twice as affordable as that of other domestic manufacturers, not to mention imported brands. The products are distinguished by neat argon welding seams, stainless steel body and good assembly. The units work correctly when mechanical impurities with a diameter of 1 mm get inside, but in an amount not exceeding 100 g per m³. The flow capacity of the ECO VINT line is 1-2 m³/h, and the head is available from 30 to 105 m.

The domestic manufacturer offers submersible pumps for wells only up to 30 m deep with and without cable. The Vodomet series has very clear model designations: the first digit indicates the capacity in liters, and the second indicates the maximum head in meters. Accordingly, equipment marked 55/35 is suitable for watering the garden, 40/50 and 40/75 for wells with a low flow rate, and 55/50 to 110/110 for automatic irrigation systems. For the entire line, the company issues a 3-year warranty - one of the best indicators among domestic manufacturers. Sand resistance allows submersible pumps to be used for flushing new wells when water is mixed with sludge. To prevent the penetration of large debris into the pump part, a strainer is provided at the inlet. But the valve to hold the pressure is plastic, which is the weak link of the entire line.

A series of submersible pumps BTsPE has centrifugal devices with power from 440 to 2500 W. They give out a head from 36 to 200 m and pump 3600-400 liters of water per hour, so the characteristics are at the level of world brands. The diameter of all pumps is 105 mm, which allows them to be used only in wells with a width of 120 mm or more. The manufacturer uses a monoblock 5-stage pump part, which prolongs its service life and protects it from damage when sand enters. The motor is removed from the pump, and this eliminates the penetration of oil into the water. To protect against overheating, a thermal relay of the German company Thermik has been introduced. The entire series comes with a 1.5 year warranty. The package includes a nylon cable for hanging equipment and a power cable - both 25 m long.

The 3JNR series of submersible pumps differs from the Belamos TF3 described below in increased productivity - 3200 l / h versus 2700 l / h. But they work at a smaller depth. Modifications in the series differ in power from 460 to 1900 W, on which the head height of 35-197 m depends.But the manufacturer saved on the cable, providing a length of 15 m for each product. The rest will have to be purchased and connected using a waterproofing sleeve. 3JNR series submersible pumps are lighter than TF3. With a body height of 665 to 1910 mm, they weigh 7-20 kg, while others weigh 9-31 kg. The special shape of the blades contributes to a stable pressure. The units are well tolerated by fluctuations in the electrical network from 180 to 250 V, so they can be used even without a voltage stabilizer.

The line of submersible pumps CH has units with power from 370 to 1800 W. Productivity is available to choose from: 1.5-3 m³ / h. Whirlwind household borehole pumps give out a head from 50 to 135 m, therefore they are suitable for low-rise buildings. In some models, instead of impellers, a monolithic shaft with pulleys (screws) is used. This reduces vibration and noise levels, and also extends the life of the working part. Externally, the modifications differ in the degree of water intake, where there is an upper and in the middle (between the impeller block and the motor).Case diameter is 75-102 mm. In the reviews, buyers like the affordable price of the CH line, high-quality metal and light weight of about 8 kg. But the equipment does not have protection against dry running, so you need to control the presence of water in the well.

The TF3 submersible pump series from Belamos is available with a power of 550-2000 W and produces 2700 liters of water per hour. The pressure is possible from 60 to 195 m, which allows you to choose a device with the desired capacity to supply water to a one-story house or cottage. The units have a stainless body and brass valves, which prolongs their service life. Built-in overheating protection protects the rotor and stator windings. While many manufacturers offer submersible pumps with a cable of 1-1.5 m, Belamos sells products with a long power cord of 35-80 m. It is three-core with double insulation. If the well depth is less than 80 m, it will be possible to get by with the wire from the kit and avoid additional expenses. But in the reviews, they note a start-up delay when automation is connected up to 2 s, when for other versions it is 0.5 s. If this does not bother you, you can safely buy.

A series of submersible pumps for deep wells 4SR from an Italian manufacturer is available for industrial and private water supply. In the case of one pump, there can be from 5 to 10 working centrifugal wheels, which contributes to high productivity. The diameter of the devices is 98-100 mm, so it is required to drill wide wells. Even for modifications with a power of 550 W, the throughput is 2.7 m³ / h. The 1100 W versions pump out over 4000 liters of water per hour, while the most productive unit with a characteristic of 7500 W pumps 22,500 liters per hour. The immersion depth varies from 70 to 100 m. There are also record holders - 4SR 4/15 F-PD can be lowered into the well to a depth of 200 m. But improved performance indicators have affected the size and weight of submersible pumps, which turned out to be more than competitors.

The manufacturer offers borehole pumps in the SQ series and kits with a hydraulic tank, cable and control panel in the SQE series. Deep wells are divided according to the height of the output pressure from 45 to 150 m and throughput from 1 to 6.8 m³ / h. The line has champions in diving depth up to 200 m, for example SQE 2-70 and 2-215. The manufacturer offers versions for 220 and 380 V for domestic and industrial facilities. All modifications are made in a stainless steel case, which perfectly resists corrosion for the entire service life. Grundfos products are highly reliable. It can be seen from the reviews that many people do not remove the deep pump from the well for years - it works properly, keeps the water level, and productivity does not decrease.
