Abstract
A centrifugal pump including a motor connected to a volute housing. The volute housing is configured to receive a pumping mechanism that includes an impeller rotatably connected to the motor. The volute housing may also include a removeable cover that provides access to the interior of the volute housing and to components of the pumping mechanism. In one exemplary embodiment, the removeable cover is connected to the volute housing by fasteners, such as bolts. By removing the cover, the impeller, wear plate, and other components of the pumping mechanism may be disassembled and, if necessary, serviced, without the need to remove the motor from the volute housing. In another exemplary embodiment, a gasket having an integrated flapper valve is secured between the cover and the volute housing. The flapper valve is positioned to align with a fluid inlet formed in the cover and acts as a check valve, substantially preventing fluid within the volute housing from exiting through the inlet.
