Introducing the LEO 4SR4-35 submersible borehole pump, a robust 4-inch pump engineered for reliable water extraction in demanding applications across mining, agriculture, aquaculture, and food and beverage industries. Built with a premium AISI304 stainless steel casing and motor base that meets NEMA standards, this pump delivers consistent performance for both industrial water supply systems and residential borehole installations. Available in single-phase (0.37-2.2kW) and three-phase (0.75-7.5kW) configurations, it provides flexible power options to suit any installation requirement.

Construction excellence defines the 4SR4-35, featuring a durable floating impeller designed from FDA-approved Noryl® material that resists corrosion and wear even in challenging downhole environments. The pump incorporates a built-in AISI304 check valve, strainer, and sealed gasket assembly to ensure long-term reliability and prevent contamination, making it ideal for agricultural water supply, mining operations, and food processing applications where water quality and durability are paramount. With a maximum sand content tolerance of 0.25% and fluid temperature rating up to 35 degC, this submersible pump excels in both clean and moderately sandy borehole conditions.
