Leo 4SR6-27 / 3KW Submersible Borehole Pump Only

Introducing the LEO 4SR6-27, a robust 4-inch submersible borehole pump engineered for demanding applications across mining, agriculture, aquaculture, food and beverage production, and residential water supply systems. Built with a corrosion-resistant AISI304 stainless steel casing and FDA-approved Noryl® impeller material, this single or three-phase pump delivers reliable performance in challenging underground environments with flow rates from 1 to 10 m3/h.

Constructed to NEMA standards with premium hydraulic design, the 4SR6-27 features a durable floating impeller mechanism paired with an integrated AISI304 check valve and built-in strainer for superior filtration and pressure protection. Its IP68-rated motor housing and robust construction make it ideal for borehole and submersible applications where durability and consistent water delivery are essential, even in slightly sandy conditions up to 0.25% sand content.
