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.

They are provided with a NEMA coupling for connection to 4” motors.

Outstanding features include the sturdiness of the head and coupling foot, made of a microfusion of stainless steel, and an adapter for holding cables of up to 7 mm.

The head always includes a check valve to protect the pump in the case of water hammer.
