JST KZN Industrial Heavy Duty Pumps 400v

The JST KZN series represents the ultimate solution for heavy-duty slurry pumping in the most challenging industrial environments. These robust submersible pumps feature integrated agitators and are engineered specifically for mine dewatering, quarry operations, construction sites, and aggregate processing applications.

Built with cast-iron bodies and featuring Hi-Chrome iron impellers, wear plates, and agitators, these pumps deliver exceptional resistance to abrasive materials including sand, sludge, slurries, and industrial waste. The precision-engineered agitator creates powerful mixing action that suspends settled solids before discharge, ensuring consistent performance in demanding applications.

The top discharge design provides superior motor cooling for continuous 24/7 operation, while the 4-pole motor configuration reduces operating speeds to extend wear part life. Double silicon carbide mechanical seals in separate oil chambers, enhanced shaft sleeves, and additional lip seal protection ensure maximum reliability in abrasive environments.

Available in High Head (H) and High Flow (L) configurations with power outputs from 3.7kW to 22kW to meet specific performance requirements. Optional hardened ductile iron volutes provide enhanced wear resistance for extreme applications. Each unit includes thermal overload protection, enhanced cable entry sealing, and 20 metres of power cable with direct on-line starting capability.

Ideal for mine dewatering, construction sites, aggregate processing, mill scale, slag pits, coal ash, drilling mud, and tailing ponds.
