SX Series Corrosion Resistant, Solids Handling Non-Clog Pumps

Corrosion Resistant Pumps for Harsh Chemical and Wastewater Environments

The BJM Pumps SX Series is designed for corrosion-resistant, solids-handling applications, providing reliable performance in aggressive liquids such as chemicals, salty water, and industrial waste.

Constructed entirely from cast 316 stainless steel with no welds, the SX Series delivers superior durability, eliminating common corrosion failure points.

Open Vane Non‑Clog Solids Handling

The SX Series utilizes an open vane impeller design that allows solids to pass through the pump while maintaining high hydraulic efficiency.

This design enables the pump to handle solids up to approximately 2.5 inches, making it suitable for wastewater, industrial fluids, and light slurry applications.

Corrosion Resistant Construction

All major wetted components, including the motor housing, volute, and impeller, are manufactured from cast 316 stainless steel, providing exceptional resistance to corrosion and chemical attack.

The cast construction eliminates welds, improving long-term structural integrity in aggressive environments.

Built for Reliability

The SX Series incorporates oil-lubricated dual mechanical seals and robust bearing systems to ensure long life in challenging conditions. Elastomers are supplied in FKM as standard, with EPDM or Buna options available for compatibility with specific fluids.

Built-in thermal and overload protection helps protect the motor from damage, while Seal Minder® moisture detection is available for early warning of seal failure.
