SUS Series – Submersible Sewage Pumps for Corrosive Wastewater with Solids
JS SUS submersible pumps are specifically engineered for handling municipal, industrial, and commercial wastewater with suspended solids in highly corrosive environments. Built entirely from 316 stainless steel and featuring non-clog channel impellers, they provide reliable performance in tough sewage applications where durability and chemical resistance are critical.
-
All exposed wet parts made of SUS 316 stainless steel for maximum corrosion resistance
-
Viton® elastomers and O-rings for excellent chemical compatibility and sealing
-
Non-clog single channel impeller ensures continuous flow with solids
-
Double mechanical seals and shaft sleeve reduce wear and extend pump lifespan
-
Additional lip seal keeps abrasives and sludge away from mechanical seals
-
Thermal overload protection guards against overheating and excess current
-
Class F motor insulation allows operation at high temperatures
-
Slide rail kits available for safe and simplified maintenance
