Structure and characteristics

Stainless steel structure designed for years of trouble-free operation. Close coupled to NEMA standard submersible motor. Designed for flow rates up to 20m³/h and head up to 350 meters.

Stainless steel impeller and diffuser ensures optimal performance in sandy wells.

Heavy duty stainless steel outer shell providing protection and accurate alignment of internal components

High quality shaft bearings providing low friction and high wear resistance

Built-in check valve prevents back flow

Strong stainless steel splined drive shaft ensures positive impeller drive and longer life

Standard 2 pole speed motor limits internal velocities for longer life

Single phase pump with control box with capacitor and thermal protection

The 4SP series pumps can be coupled 4SD(M) motors
