We offer the TOP 15 best models of pumps of different mechanisms of action with a description of their operating parameters and an assessment of strengths and weaknesses. The following selection tips will help you decide on the appropriate option for organizing water supply for a private home, cottage, watering your garden and vegetable beds.

How to choose and what to pay attention to?

When choosing a pump for a well, you should pay attention to the following criteria:

  • Productivity . The pump for the well must cover at least 50% of the total water consumption in the water supply system and at the same time not exceed the flow rate of the well (so as not to suck water out of the well faster than it is collected there). The well flow rate can be viewed in the installation passport.
  • Maximum immersion depth . Here we mean the depth of immersion under water, and not generally into the well. For example, if the well has a total depth of 50 m, but from the surface to the water table is 20 m, then there is 30 m of water space, and if you want to lower the unit almost to the very bottom, then its maximum immersion depth should be at least 30 m.
  • Power cord length . The power cord must be at least as long as the total depth of the well (if lowered to the very bottom) plus the distance to the outlet.

How to choose a pump for a well

  1. Productivity
    . You should not chase high pump performance if the capabilities of the well or borehole are unknown. The fact is that the filling of each water source is very different. It is very good when the well was done by professionals, after which they provided the owner with a passport with the necessary data. Then the pump capacity is selected less than the filling capacity of the well. But for old wells it is necessary to experimentally determine the volume of water that flows per unit of time. The capacity of well pumps ranges from 1 to 10 cubic meters. m/h. A pump with a capacity of 1-3 cubic meters per hour can fully provide water to summer residents.
  2. Pressure
    In order for water to flow from the tap with good pressure, and not a thin trickle, it is necessary to take into account such a parameter as the maximum pressure. It can be calculated as follows. 30 is added to the depth of the well (well), and 10% is added to the resulting number. In the case of a 10-meter well, the optimal pressure value will be 45 m.
  3. Not all buyers pay attention to water quality when choosing a pump. If we are talking about supplying clean liquid from a well, then any model with the necessary set of characteristics will do. But in case of water contamination with sand, it is better to give preference to a screw pump, which does not fail due to solid particles getting inside.
  4. All pumps for wells are divided into two groups: submersible and surface. They have their pros and cons.
  5. Submersible models
    are capable of supplying water from great depths. Therefore, they are recommended to be purchased by owners of wells with a depth of more than 10 m. In this category of pumps, vibration, screw and centrifugal installations compete with each other. The most accessible of them are vibration “streams” and “babies”. But with prolonged use, the well is destroyed and the wells become silted. Therefore, you should not spare money; servicing a well or well will later turn out to be a more expensive project.
  6. Surface models
    are capable of sucking water only from shallow wells and boreholes (up to 10 m). They are good because they work indoors and are easy to control and maintain.

Our review included 14 of the best pumps for wells. When compiling the rating, the opinions of experts and reviews of domestic users were taken into account.
