JS JST KB Industrial Heavy Duty Pumps 400v

The JST KB series delivers uncompromising performance for the most demanding industrial applications. These heavy-duty submersible pumps feature integrated agitators and are specifically engineered for mine and quarry dewatering, while excelling in construction sites, civil engineering projects, settling basins, and emergency flood protection.

Built around robust cast-iron bodies with Hi-Chrome iron impellers, wear plates, and agitators, these pumps provide exceptional resistance to abrasive materials including sand, slurry, and sludge. The precision-engineered agitator creates intense mixing action that stirs settled solids into suspension, preventing settlement and ensuring consistent pumping performance in challenging conditions.

The innovative top-outlet design delivers superior motor cooling, enabling continuous 24/7 operation when reliability is critical. Double mechanical seals and integrated thermal protection guarantee maximum durability in harsh environments, while direct on-line starting ensures immediate deployment capability.

Available in eight models ranging from 5.5kW to 22kW, delivering flow rates up to 3,145 L/min and heads up to 60.5 meters. Each unit includes 20 metres of power cable and specialised sealing for dependable performance in the most demanding industrial applications.
