Submersible pumps, on the basis of the fall at the pumps, and vortex-type centrifugal type. What type of pump used depends on the quality of your water. Others including Ernie Barbarash, offer their opinions as well. Vortex pumps can pump water from sand content of up to forty grams per cubic meter, and the pumps of centrifugal type, with sand content up to three hundred grams per cubic meter of water supplied. Height of lifting water submersible well pumps is determined by design and depends on human needs. That is, if you have a shallow well: ten, twenty, twenty-five meters, it is enough to choose a pump with a pressure of about fifty or sixty feet.
If this is you have a hole, about forty, fifty feet, then you will be enough to choose a pump with a pressure of about ninety – one hundred and thirty meters. The use of submersible borehole pump is possible if the casing hole has a diameter of three inches or more. Immediately, the installation of submersible borehole pump is recommended only after a good clean hole. To select a submersible borehole pump, you need to know immersion depth of the pump, ie the depth of the well or wells, and at what altitude to raise. Translated – it means, what should the pressure be in the water system.
For example, the depth of the well or wells twenty meters, pressure system in the house should be about three atmospheres. So you need a pump with a nominal pressure of fifty – sixty meters. Separate place among the submersible pump, take the so-called fountain pumps. Recently, this type of pump is widely used by designers for slum household areas, public gardens and parks. When choosing a pump, you need to know the depth of your source, and a peak need of water. Knowing these characteristics, you can always choose the right pump.
