GRINDER PUMP WITH REGENERATIVE IMPELLER

摘要

A pump is provided to convey solids-containing wastewater from a basin, such as a sewage basin. The pump has a pump housing that is adapted to be arranged in the basin with an inlet thereof positioned to receive the solids-containing wastewater. An outlet of the pump housing is arranged to eject pressurized wastewater through an outlet of the basin. A pump chamber is arranged in a flow conduit formed in the pump housing between the inlet and the outlet. A regenerative turbine impeller is arranged for rotation in the pump chamber. A grinder is also arranged for rotation in the pump housing between the inlet and the outlet, especially between the inlet and the pump chamber.
