※ Powerful and robust highefficiency pumps made entirely of stainless steel
※ Constructed entirely from stainless steel, BC-ST submersible pumps offer
superior corrosion and abrasion.
PERFORMANCE RANGE
- 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 in-creased pressure for pumping solids up to 50 mm in diameter, making it the best choice for wastewater drainage.
INCLUDES
※ Power cable length 10 m
※ Float switch (exclusive to single-phase models)
APPLICATION LIMITS
- Depth below water level up to 5 m (with an appropriately sized power cable)
- Liquid temperature up to +40 °C
- Capable of processing suspended solids up to Ø 50 mm
- Minimum immersion for continuous service:
– 290 mm for BC 10/50-ST
– 330 mm for BC 15/50-ST
– 360 mm for BC 20/50-ST
AVAILABLE UPON REQUEST
※AISI 316L stainless steel pump shaft
※ Different voltage requirements 60 Hz frequency
