JS Series – Submersible Dewatering Pumps for Wastewater, Drainage & Site Water Removal
JS submersible pumps are designed for reliable dewatering in construction, utilities, and effluent management. With a top-discharge motor-cooling design and robust sealing systems, they perform exceptionally in general drainage, sump emptying, and light wastewater applications.
-
Top discharge design ensures effective motor cooling in tight or confined spaces
-
Double mechanical seals (from 0.25 kW and above) ensure long-lasting leak protection
-
Class F motor insulation handles high operating temperatures
-
Shaft sleeve & lip seal minimize wear from abrasives and reduce maintenance
-
Thermal overload protection prevents motor burnout from high amperage or overheating
-
Enhanced cable entry ensures long-term sealing and durability
-
Slide rail kits available for easier and safer pump removal during maintenance
