The Efaflu BFS Submersible Borehole Pump is a heavy-duty multistage centrifugal pump designed for high-capacity groundwater extraction in demanding environments. Built with robust cast iron construction, it is ideal for agricultural irrigation, industrial water supply, and large-scale water transfer systems.
The BFS series is available in large diameters ranging from 6 inch to 10 inch, with options extending up to 24 inch for high-volume applications. It delivers exceptional hydraulic performance with flow rates up to 400 m³/h and heads reaching up to 398 meters.
Constructed with EN-GJL-250 cast iron components, the pump ensures durability and resistance to mechanical stress. The shaft is made of AISI 304 stainless steel for enhanced corrosion resistance and long service life.
The pump is designed to ensure proper motor cooling during operation and is fully compatible with NEMA standard motors. Optional configurations include bronze or stainless steel impellers and diffusers, cooling jackets for installation in wells or tanks, and horizontal installation for selected models.
