When choosing a pump for a well, it is necessary to be guided by the principles of implementing a competent and justified water supply.
First of all, know the depth of the well. After all, the pumps are:
- superficial;
- submersible.
Can have both automatic and manual control mode.
If you know the operating conditions of the pump, the depth of the well, then it is not difficult for you to make the right choice. And if not? Let's try to understand which pump is better for the well.
Submersible pumps are designed for places with deep water distribution up to 80 meters, but not less than one meter, have higher power, while working partially or completely under water, that is inside the well, and the diameter of the well must be not less than 100 mmor 4 ".The main application is to raise water from a great depth for further use in water supply. Water supply can be not only at home, giving, but also for industrial and agricultural purposes. They are also used for irrigation or watering. Submersible pumps have a very well-protected housing, which eliminates water ingress and ensures cooling of the motor.
Submersible pump for
Well A second important factor in the selection of a well or artesian pump is the sand content in the water and the presence of water in the well.
Submersible pumps are:
- vortex;
- screw;
- centrifugal.
Vortical is used to lift water from a well with a maximum sand content and a small water content. The device of this type creates a lot of pressure with a small water supply. The performance of such a pump is not very high.
Vortex pump for
Well is used to lift water from a well with a low sand content. A distinctive feature is the ability to supply water not only from wells, but also from open reservoirs. Pumps of this type are distinguished by a lower price.
Well Screw Pump Sample Centrifugal is used to lift water from a well with a high sand content, designed to pump water from the deepest wells. Such pumps have high efficiency and reliability.
Sample of centrifugal pump
Surface( non-submersible) - the body is remote from the place of pumping water, with a maximum suction depth of up to about eight meters, the minimum depth can be only a few centimeters. So for deeper wells such a pump is hardly suitable.
Despite the different power of the pumps, both types are very compact and can pump a considerable amount of water.
So which pump to choose?
Two basic parameters should also be considered when selecting:
- performance;
- head.
The need for water per person per day is about 1000 liters. Multiplying the number of people living on 1 m3 of water can get the required amount of necessary water.
With additional water consumption for irrigation of a garden plot or garden, for example, it is necessary to take into account the size of the land plot.2 m3 or 2000 liters per day is usually sufficient.
To determine the necessary pressure, you need to add such values as the height of your house in meters, the depth of the well, add an additional six meters and multiply the result by the head loss factor in the pipeline, which is 1.15.
Provided that the well is removed from the house, it must also be taken into account that for every 10 meters of the length of the pipeline, which is located horizontally, one more meter of head is lost. Ensuring maximum water flow can be achieved with a hydraulic accumulator.
The simplest and most reliable way of extracting water from a well, although not very convenient, is a hand pump that will help you out in the event of a power outage. Many necessarily install it on their sites, because it will help you in case of malfunctions with electric pumps, lack of electricity. Do not forget that the depth of the well for using such a pump should not be more than eight meters. It is worth noting that the hand pump is the cheapest of all available.
It should be said that it is necessary to choose the pump especially carefully, because the right choice is characterized by reliability, efficiency of the water supply system in your home. It is better to entrust this issue to specialists who are ready to correctly calculate the necessary productivity and pressure, as well as carry out installation work. You will only have to follow the recommendations for use and enjoy a comfortable stay.
