Non Clog Sewage Submersible Manhole Pump “MSEW” Series

The pumps in the “HET” brand’s “MSEW” series are single shaft, single stage, non-clog type, submersible, equipped with temperature and moisture sensors, dual mechanical seals, open/semi-open/close, vortex, single vane, two vane, and multi-vane impellers. “F” class A.C. squirrel cage induction motor. These pumps have a robust design and excellent performance capacity.

The “MSEW” series pumps made by “HET” are specifically made for use in manhole applications for hospitals, nagapalikas, and municipalities. Usually, primary and secondary treated sewage is used with this configuration. Because of their carefully designed impellers, these pumps offer excellent dependability against clogging and the capacity to readily clear things that have become lodged inside the pump. The pumps are capable of handling liquids with solids as small as 20 to 100 mm. The most popular uses are dewatering applications in slurry water, drain water, water treatment, wastewater treatment, and industrial effluents. Manhole applications are also frequent, where sump sizes are limited to 460 mm (18”) & 600 mm (24”) in sewage treatment. The pumps provide the maximum flexibility and dependability thanks to their highly efficient submersible motors, full feature pump monitoring systems, and VFD operation options.
