Artesian type" a "pumps are designed for wells up to 30 m deep. Pumps of this type can pump water with a temperature of up to 40 ° C, clean or with dry materials without abrasive materials up to 0.50 g/ l.
Artesian pumps vertical, multi-stage, centrifugal or diagonal. The pumping part is associated with the supporting knee using a tube column consisting of individual sections and intermediate shafts interconnected by sliding bearings. Thus, pumping units of various lengths can be made, depending on the distance between the foundation and the level of water.
In the basic version, the pump is set in motion using a flange electric motor. Also, pumps of pumps can be carried out using other types of electric motors.
