BJM Submersible Pumps

BJM pumps remove or transfer water, wastewater, and solids-containing liquids in industrial and municipal settings. Applications include construction dewatering, process sumps, mining, power generation, food processing, and wastewater handling.

BJM offers dewatering, solids-handling, shredder, slurry, corrosion-resistant, and high-temperature pumps. The appropriate product family depends on the liquid chemistry, solids, temperature, and required flow and discharge head.

Yes. BJM offers pumps for abrasive sand, sludge, and slurry applications, including the KZN Series. Particle size, hardness, concentration, and slurry density should be evaluated when selecting the hydraulic design and wear components.

An agitator helps disturb settled solids near the intake so they can enter the pump with the liquid. It does not make every settled material pumpable, so solids characteristics and available liquid remain important.

A BJM shredder pump incorporates cutting components to reduce suitable solids during pumping. These designs serve wastewater applications where fibrous or other troublesome material can interfere with conventional solids-handling equipment.

Shredder pumps focus on cutting suitable debris, while slurry pumps emphasize moving abrasive solids and resisting wear. A waste stream containing both fibers and grit requires evaluation of both challenges before equipment selection.

Yes. BJM’s Fahrenheit range includes pumps designed for hot-liquid service. Confirm the continuous and intermittent temperature ratings of the exact model, along with liquid compatibility, cooling requirements, and the intended operating cycle.

Yes. BJM offers stainless steel and nonmetallic pump options for selected corrosive applications. Confirm compatibility with the chemical, concentration, temperature, and all wetted components rather than choosing solely by the housing material.

Many BJM pumps are designed for solids-containing wastewater. Allowable solids size and concentration vary by model, and fibers or abrasive particles may require a different selection than soft solids of similar dimensions.

Provide the required flow and total dynamic head, liquid temperature, solids characteristics, and chemical properties. Include sump dimensions, available voltage and phase, and the expected operating schedule for an application-based selection.

Selected models are designed for continuous duty under specified conditions. Verify the duty rating, minimum liquid level, cooling requirements, and allowable operating range for the chosen pump rather than applying one rating across the entire brand.

Dry-running limits depend on the model and cooling arrangement. Check the operating instructions and provide appropriate level controls or protection when the sump could empty or the incoming liquid supply could stop.

A properly configured installation can use compatible float switches or level sensors to control pumping. Select operating levels that meet the pump’s requirements and consider alarms where delayed water removal could disrupt operations.

Follow the model-specific schedule for checking impellers, seals, bearings, cables, and applicable wear components. Abrasive service may require more frequent inspections, while shredder applications also require attention to cutting-component condition.

Repair may be practical when replacement components can restore dependable performance. Compare the condition of the motor, housing, and hydraulic components with repair costs, replacement costs, and any changes in the application.
