Integral, multi-stage, submersible, centrifugal electric pumps with floating impellers for wells from 4”.

Specially designed for supplying homes, farms, irrigation sprinklers and pressure equipment from wells. Manufactured with floating impellers made from high-quality thermoplastic material providing excellent resistance to the effects of abrasion and blocking of the hydraulic system by sand in the wells. The electric motor has been built-in at the top position to guarantee proper cooling at all times via the delivery water.

The compact design of the pump allows effective cooling of the motor even when installed in open wells, tanks or ponds; it has also been designed so that its suction via the bottom enables better exhaustion of the suction tank.

In drilling installations it allows the exploited dynamic level to be increased.
