Heavy‑Duty Slurry Pumps for Hazardous Environments
The BJM Pumps XP‑KZN Series is designed for abrasive slurry, sludge, and solids‑handling applications in hazardous environments, combining explosion‑proof safety with extreme-duty construction. Engineered for demanding industrial conditions, the XP‑KZN Series delivers reliable pumping of sand, silt, and slurry while minimizing wear and downtime.
The XP‑KZN Series features an FM‑approved explosion‑proof motor rated for Class I, Division 1, Groups C & D hazardous locations, ensuring safe operation in environments with flammable gases or vapors.
Engineered for Heavy Solids and Slurry Handling
The defining feature of the XP‑KZN Series is its ability to handle abrasive materials. A high‑chrome agitator (28%) continuously suspends solids, preventing settling and improving pumping efficiency. The combination of hardened ductile iron components and high‑chrome wear parts provides exceptional resistance to abrasion and extends pump life.
The XP‑KZN Series uses a semi‑open hard metal impeller and agitator system designed specifically for slurry movement. This allows the pump to handle solids up to approximately 1 inch, depending on the model. The top discharge design also improves motor cooling and allows for lower pump-down levels.
Heavy‑Duty Construction for Extreme Conditions
All key components are built for durability, including a hardened ductile iron volute, heavy-duty bearings, and robust shaft design. The motor is cooled by the pumped liquid, allowing for continuous operation in challenging environments.
The XP‑KZN Series features dual silicon carbide mechanical seals in an oil-filled chamber, providing superior resistance to abrasion and leakage. The Seal Minder® system and embedded thermal protection ensure early detection of issues and protect the motor from damage.
