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. They include a suction grille with 4.5 mm pitch to prevent the entry of solids into the hydraulic part.
The head always includes a check valve to protect the pump in the case of water hammer.
