The lack of the centralized water supply forces owners of many dachas and owner-occupied dwellings to use water from wells and wells. That she moved trouble-free and with good pressure, it is necessary to choose the pump correctly.
Instruction
1. The defining factor when choosing type of the pump is the distance from earth surface to water mirror in well or the well. If it does not exceed 5-7 meters, it is possible to use the centrifugal pump installed above. If is more deeply, it is necessary to stop on the submersible models lowered directly in water.
2. By operation principle the submersible pumps are divided into vibration and centrifugal. "Kid" famous to much treats the first, example of representatives of the second type are pumps of the Aquarius brand.
3. Choosing the pump, consider also whether you will use water supply system in winter time. The land centrifugal pump needs to be warmed or placed in the warm room as on cold the frozen water can break off its body. The centrifugal pump cannot be placed far from well or the well, this distance should not exceed three meters.
4. Also the fact that it badly works at the differences of tension frequent for rural zone and holiday villages belongs to shortcomings of the centrifugal pump. Weak mains voltage can not be enough for that the electric motor of the pump was untwisted. When using automatic system of water supply to the house it can lead to operation of protection of the pump (thermorelay) or, in the absence of that, to burn-out of its winding.
5. In this plan submersible pumps are more unpretentious and reliable. They are not required to be warmed, they can pump water from depth in dozens of meters. The majority of submersible pumps, except the "Kid" providing rather small water supply are suitable for work with hydroaccumulators and the systems of automatic switch-on. It allows to automate water supply, there is opportunity to use any plumbing.
6. When choosing the submersible pump you proceed from depth with which it is required to pump water, and your financial opportunities. Vibration pumps can swing up to several dozen meters from depths. Centrifugal – for example, "Aquarius", depending on modification can lift water from depths to 150 meters. But also cost is higher than them. As the electric motor is installed in the body of such pumps, they need stable supply voltage.
