Barmesa SW Series Solids-Handling Submersible Pumps

The Barmesa SW Series is a heavy-duty line of solids-handling submersible pumps engineered for municipal wastewater, sewage lift stations, industrial wastewater, stormwater management, and other demanding pumping applications. Available in multiple hydraulic configurations and horsepower ranges, the SW Series combines high-efficiency performance, robust construction, and reliable solids handling to deliver dependable operation in challenging environments.

The SW family includes the 4SWL, 4SWM, 4SWH, 6SWL, 6SWM, 6SWH, 8SWL, 8SWH, and 12SWL models, with discharge sizes from 4" to 12", horsepower ratings from 7.5 HP to 150 HP, and solids handling capabilities up to 5.25 inches depending on the model.

Designed for long service life, SW pumps feature rugged cast iron construction, ductile iron enclosed impellers, stainless steel shafts and hardware, and epoxy-coated surfaces for corrosion resistance. Premium-efficiency oil-filled motors, continuously lubricated bearings, and tandem double mechanical seals operating in an oil-filled chamber help maximize reliability while minimizing maintenance requirements.
