Submersible semi-open vortex impeller sewage pump

Model DVFU

The model DVFU submersible pumps are made of tough cast iron with heavy-duty motors suitable for industrial and municipal water and sewer water, drainage and sewage applications where the discharge water or the pumpage contains fibrous or large solids. The high-efficiency, semi-open recessed vortex impeller makes it possible to pass abrasive and large, suspended  solids up to 5″ and works to prevent clogging. The model DVFU are available with FM motors.
