Leo 4SR3 Submersible Borehole Pump Series (100mm)

Introducing the LEO 4SR series, a robust 4-inch submersible borehole pump engineered for reliable deep-well water extraction across diverse industries. This versatile submersible pump excels in mining, agriculture, aquaculture, food and beverage production, and residential water supply applications. Built to deliver consistent performance in demanding environments, the 4SR series combines precision hydraulic design with industrial-grade construction to handle continuous operation in borehole and well applications.

Constructed from premium AISI304 stainless steel casing and motor base meeting NEMA standards, this submersible borehole pump features a durable floating impeller made from FDA-approved Noryl® material that resists corrosion and wear. The pump incorporates a built-in AISI304 check valve, integrated strainer, and sealed outlet design to ensure long-term reliability in agricultural irrigation, aquaculture systems, and industrial water supply scenarios. With IP68 protection rating and available in single-phase (0.37-2.2kW) or three-phase (0.75-7.5kW) configurations, it's ideally suited for continuous duty pumping of clear to slightly sandy water with minimal maintenance.

Choose the model whose performance table gives the head you need (pumping level + delivery height + friction) at your required flow, and never exceed the borehole yield.
