Leo 4SR1-38 / 1.1KW Submersible Borehole Pump Only
12331
The LEO 4SR1-38 is a 4-inch (100 mm) stainless steel submersible borehole pump end from the 4SR1 series, with 38 stages and a 1.1 kW rating. The 4SR1 hydraulics are sized for a nominal 1 m³/h with an operating range of 0 - 1.5 m³/h (0 - 25 l/min); the high stage count gives the head needed for deep boreholes and long pipe runs. This is the pump end only: it couples to a standard 4" NEMA submersible motor of 1.1 kW, sold separately.
The 4SR range uses an AISI304 stainless steel outer casing, shaft and motor bracket, with floating Noryl® impellers (FDA-approved material) that tolerate small amounts of sand. A built-in AISI304 check valve and inlet strainer protect the pump and the rising main. Typical uses are farm and game-farm water supply, irrigation, livestock watering, domestic and estate borehole systems, and mining and building-site water supply.
