In country houses, it is almost impossible to connect to a central water supply. What to do? Run your own water supply system, make a well or a well. The second option is more convenient, but requires a lot of different solutions.

How to choose a deep well pump?

Thanks to our online calculators for calculating the power of the pump for wells, it is possible to solve the given question within a few minutes, considering a few parameters for determining the accuracy of the received response. This will be true for submersible and surface well pumps.

Well parameters:

  • depth;
  • water quality;
  • volume of water pumped per unit time;
  • the distance from the water level to the ground surface;
  • pipe diameter;
  • daily volume of used liquid.

Yes, this is a very troublesome business, it requires precise engineering approaches, as well as the study of many formulas for calculating the power of submersible and surface pumps and tables that will help you to accurately determine the required parameters.

Self-calculation of pump power

How can I select the pump for a well according to the parameters of the unit without professional assistance? It is possible, first of all, to take into account the head and flow rate of the well. Flow - the volume of water for a certain amount of time, and the head - the height in meters, on which the pump is able to supply water.

To calculate the pump's power for a well, it is necessary to take the average water rate per person per day 1 cubic meter, after multiplying this number by the number of people living in the house.

An example of calculating the calculation of sediment thickness for a small house:

It turns out that a family of three spends 22 liters per minute, but one should also take into account the force majeure circumstances that will increase the water demand for a person. Because some average figure will be 2m cubic a day. It turns out: 5 m cubic - daily water flow.

Next, the maximum characteristic of the pump head is determined, for this, the height of the house in meters is increased by 6 m and multiplied by the head loss factor in the autonomous water supply system, which is 1, 15.

If the calculation of the height is done at 9-meters of the house,of the thickness of the deposit by the formula like this:( 9 + 6) * 1.15 = 17.25.This is the minimum characteristic, now to the calculated head, you need to add the distance from the water mirror in the well to the surface of the earth. Let there be a number of 40. What happens?40 + 17.25 = 57.25.If the water source is 50 meters from the house, the pump should have a head pressure: 57.25 + 5 = 62.25 meters.

Here is such an independent formula for calculating the pump's power for a well in kW.Exactly the same figures can be obtained with online calculation, using a simple table, in which the customer should enter data about the depth of the well, the water mirror, the area of ​​the site, the number of people living in the house, and provide additional information on the number of showers,room, washbasin, the presence of a washing machine, dishwasher and toilet.

Calculations are done in a single mouse click. They are reliable and relevant for the validity period of the received data from the consumer.

Tipsspecialists in the operation of pumps

What else does a person need to know in order to establish the quality of the water supply system in the house? Pumps come in several types: submersible, surface, in the form of stations.

  1. Surface - are of low cost, designed for work without immersion in liquid. Recommended for work up to 7 meters, otherwise the water will be dirty and substandard.
  2. Submersible - centrifugal, reliable and productive, help to effectively purify water from sand. To date, these are the most popular and popular models. Screw - work not only at home, but also in open water.
  3. Pumping stations .

Important: is inadmissible to save on pump power, thus the autonomous system will not be able to thoroughly clean the cleaning filters by running the house with dirty water. Also it is necessary to take into account that some manufacturers in the product passport indicate the maximum characteristics of the goods, but you need to pay attention to the nominal parameters - workers, so that the performance was normal, without pitfalls and other troubles.

Before calculating the power of the pump for the well, it is necessary to take care of the quality of the pipe system that will pass water at a certain pressure. These are metal and polypropylene products. The latter - are much more often used in everyday life, but have low stability with temperature drops and pressure in the system.

Warning: pump is selected for a long time, and therefore it is important to familiarize yourself with all market offers by choosing well-known brands with the availability of service centers for the repair and maintenance of your system.

Tip : it is better to take the pump with the automatics, if the motor overheats, the system will stop automatically, otherwise it will fail.
