Semi-submersible. Pumps of this type have a body of a special shape. They are used most often for installation in wells, very wide boreholes or kopankah (directly on water). The engine of such models is located on the surface, the suction system is under water.
Submersible. Since today in most areas water is obtained from narrow deep wells, such centrifugal household water pumps enjoy the greatest popularity among consumers.
