SW Series Solids-Handling Submersible Pumps Information

Built for Tough Wastewater and Solids-Handling Applications

The Barmesa SW Series is designed for operators who need reliable submersible pumps capable of handling wastewater, sewage, and suspended solids in demanding applications. Whether installed in a municipal lift station, industrial facility, stormwater system, or wastewater treatment plant, the SW Series delivers dependable performance through a combination of rugged construction and efficient hydraulic design.

What makes the SW Series stand out is its focus on durability and long-term operating reliability. Heavy cast iron housings, ductile iron impellers, stainless steel shafts, and corrosion-resistant hardware are designed to withstand harsh wastewater environments. The pumps use enclosed mono-vane or dual-vane impellers with pump-out vanes to provide efficient solids handling while maintaining hydraulic performance. Depending on the model, pumps can pass solids up to 5.25 inches in diameter.

Barmesa also incorporates several features intended to help reduce downtime. The double mechanical seal system operates within an oil-filled chamber to improve seal life, while moisture sensors provide early warning if water enters the seal chamber. Temperature sensors help protect the motor from overheating, and permanently lubricated bearings reduce maintenance requirements.

The SW Series offers a broad range of sizes and performance options. Models are available with 4", 6", 8", and 12" discharges and horsepower ratings ranging from 7.5 HP to 150 HP, allowing operators to match pump capacity to the demands of their system. Premium-efficiency oil-filled motors, Class H insulation, and heavy-duty construction make these pumps suitable for continuous-duty wastewater service.
