The LEO 4SR16-8 is a robust submersible borehole pump engineered for reliable water supply, irrigation systems, and air conditioning circulation applications. This single-impeller centrifugal pump delivers up to 220 m3/h at heads reaching 85 meters, making it an ideal choice for deep well installations where consistent performance and durability are paramount.
Built with a stainless steel AISI304 impeller and cast iron HT200 construction, the 4SR16-8 features axial intake and radial discharge design that maximizes hydraulic efficiency in demanding conditions. Its closed-construction motor with external ventilation, IP54 protection rating, and rear-entry design for easy maintenance ensure long service life across residential and commercial water transfer applications, while the internally lubricated mechanical seal compliant with DIN 24960 eliminates the need for external lubrication systems.
