A: The pump can efficiently handle solids up to 50mm in diameter.

Stainless steel submersible pumps
Powerful and robust high-efficiency pumps made entirely of stainless steel

Constructed entirely from stainless steel, BC-ST submersible pumps offer superior corrosion and abrasion.

• Flow rate up to 850 l/min (51 m3/h)
• Head up to 17 m

INSTALLATION AND USE

BC-ST stainless steel submersible pumps are designed to drain dirty and sewage water in domestic, civil, and industrial settings. Featuring a TWO-CHANNEL impeller, they can efficiently pump liquids containing suspended  solids up to 50 mm in diameter with short fibers and handle wastewater, sewage, surface water, and sludge-mixed water in residential properties.

• The hydraulic configuration of the volute and TWO-CHANNEL impeller results from advanced fluid dynamics calculations, delivering superior performance and efficiency for notable energy savings.
• The TWO-CHANNEL impeller provides excellent performance and high energy efficiency, generating increased pressure for pumping solids up to 50 mm in diameter, making it the best choice for wastewater drainage.
