Introducing the LEO 4SR8-6 submersible borehole pump, a robust 4-inch pump engineered for reliable deep-well water extraction across diverse applications. Built with an AISI304 stainless steel casing and designed to handle flow rates from 1 to 10 m3/h, this submersible pump is ideal for agriculture, aquaculture, mining, building construction, food and beverage processing, and residential water supply systems. Its versatile power options-ranging from 0.37 to 7.5 kW in both single-phase and three-phase configurations-make it adaptable to various installation requirements and grid specifications.
Quality construction throughout defines this borehole pump, featuring a durable floating impeller manufactured from FDA-approved Noryl® material that resists corrosion and wear even in challenging downhole conditions. Protected to IP68 standards with an AISI304 motor base meeting NEMA specifications, the 4SR8-6 incorporates a built-in AISI304 check valve, strainer, and precision gaskets to ensure long-term reliability. With a maximum sand content tolerance of 0.25% and fluid temperature capability up to 35 degC, this submersible pump excels in applications requiring consistent performance in slightly contaminated water environments.
