Owners of seasonal dachas and owner-occupied dwellings which have faced need to adjust autonomous water supply should resolve also issue of the choice of the submersible pump which is important part of feed system of water. This choice depends on many parameters and therefore not always is such simple as it would be desirable.
Types of submersible pumps and field of their application
Submersible pumps which, as follows from their name, work in the conditions of partial or full immersion to the soil can be used at rather big depths and are used, including, for water supply from wells. By the principle of work they can be subdivided into vibration and centrifugal. The first, pumping water due to vibrations, do not enjoy special popularity as their work is followed by hashing of deep layers of water and its turbidity. The design of centrifugal pumps allows to avoid it.
Pumping submersible stations can work in different conditions. Depending on for what purposes you need the pump, you can select it according to functional purpose: water, drainage, fecal, well or borehole. Water pumps are intended for supply of clear water from bottom of natural reservoirs as well as well. The last can keep working capacity and at partial immersion as the water intaking opening is located at them in the lower part of the body.
For wells, up to 350 m in depth borehole pumps are used. These deep pumps are calculated on pumping of the water which is not containing mechanical impurity. By means of the drainage pump you can pump water on the site, having established it in the next stream or even ditch – to it neither sand, nor small stones, grass and garbage are terrible. They can also pump out water from open reservoirs, the flooded basements or pools.
For strongly polluted sources of water it is possible to use the fecal submersible pump which is equipped with the crushing nozzle. These pumps establish in waste holes in the absence of self-exact sewerage system.
Buying the submersible pump for installation in well, pay attention that it had float switch disconnecting the pump from water supply system at abatement of the water level is lower than critical.
As it is correct to choose the submersible pump
Naturally, you easily choose the pump on type, knowing conditions of its application. But, besides, you need also to know what its performance and pressure have to be to be sure that it will be able to satisfy need of your family for water.
On the family of 4 people living on the site of 6 hundred parts, enough pump with a performance about 20 liters/minute.
It is possible to determine daily requirement by Construction Norms and Regulations. According to them, on each person living in your house about 200 l of water a day are necessary. Besides, on watering of one square meter of kitchen garden about 4-6 liters are required. Knowing daily requirement, you easily solve, the pump with what performance is necessary for you. It is possible to calculate pressure of water necessary for you, knowing that on each 10 m of vertical water supply 1 meter of pressure is necessary. You will be able to choose the specific producer and the brand, having got acquainted with responses of consumers on the Internet.
