JFT Series – Submersible Pumps for Effluent Water, Sump Emptying & General Dewatering

JS JFT submersible pumps are engineered for heavy-duty dewatering of wastewater, sump drainage, and general industrial applications. Designed with robust construction and high-flow capabilities, JFT pumps handle demanding environments that involve solids-laden fluids, abrasive particles, and extended runtime.

Double mechanical seals for reliable sealing and protection in harsh environments
Class F motor insulation allows safe operation at elevated temperatures
Shaft sleeve minimizes wear caused by abrasive materials and extends motor life
Additional lip seal prevents entry of impurities and prolongs mechanical seal life
Thermal overload protection defends against excessive current and overheating
Slide rail kits available for fast, safe pump removal during service or inspection
Three-phase power compatibility from 200V to 600V for industrial applications
