Heavy‑Duty Wastewater Pumping for Solids Handling
The BJM Pumps S Series is designed for solids-handling wastewater applications, combining high-performance hydraulics with durable construction. These pumps are engineered to handle dirty water, wastewater, and fluids containing suspended solids in demanding environments.
With high flow capacity and robust components, the S Series delivers reliable performance in municipal, industrial, and commercial wastewater systems.
Built for Wastewater and Solids Handling
S Series pumps utilize dual vane, non-clog impellers designed to pass solids efficiently while maintaining hydraulic performance. The construction features a cast iron pump body with a stainless steel motor housing, providing durability and corrosion resistance in wastewater environments.
The design supports continuous-duty operation in demanding conditions with high solids content.
