non clog submersible sewage pump sew series

The SEW series pumps manufactured by “HET” include a single shaft design in a single stage, are non-clog type, submersible, and equipped with temperature and moisture sensors. They also feature dual mechanical seals, vortex, open/semi-open/close, and single, double, and multi-vane impellers. A.C. induction “F” class squirrel cage motor. These pumps have a robust design and excellent performance capacity.

The “HET” brand of “SEW” series pumps is made to handle liquids mixed with solids. Primary and secondary processed sewage are usually handled by this design. Thanks to their specifically designed impellers, these pumps have a high degree of dependability against clogging and the capacity to easily remove things that have become lodged inside the pump. The pumps are capable of handling liquids with particles ranging in size from 20 to 125 mm. The most widely used applications in sewage treatment are for return activated sludge (RAS), surplus activated sludge (SAS), and waste activated sludge (WAS). Dewatering applications are also widespread in water treatment, wastewater treatment, and industrial effluents. Pumps with high efficiency submersible motors, full featured pump monitoring system, and VFD option provide maximum flexibility and dependability.
