The CZ-series is a submersible smashing cutter pump specially designed for pumping sewage and wastewater containing various solid waste including fibrous materials. A unique design of heart-shaped suction cover equipped with a sharp-edged stationary blade along with an improved semi-open channel impeller having two sharp-edged vanes incorporates the scissor mechanism. This innovative scissor-like mechanism remarkably enhances the solid handling capabilities. It prevents pump clogging through crushing and shredding of solid objects.

In addition to that, the extended rotating guide equipped on impeller prevents the retention of solid waste at the central part of the impeller, thereby providing a smooth pumping operation.
