Specially designed for supplying homes, farms, irrigation sprinklers and pressure equipment from boreholes.
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 from stainless-steel micro-fusion and an adaptor for holding cables of up to 7 mm. They include a suction grille with a 4.5 mm gap 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.
