Abstract
A centrifugal pump (10) having a pump housing (40) that defines a substantially axial inlet port (32), a substantially radial inlet port (34) and an outlet port (30). An impeller (42) is rotatable within an impeller chamber (58) defined by the housing and is operative to pump fluid from one or both of the inlet ports to the outlet port when the impeller is rotated. A removable cleanout assembly (82) located within and forming part of the axial port includes a structure for supporting a wear plate (76) that is positioned axially adjacent the impeller. The cleanout assembly includes an inlet opening adapted to be configured as an axial inlet port to the pump. The cleanout assembly is removable in order to provide access to the impeller for service or cleaning. Either the axial port or the radial port can serve as an inlet or, alternately, both ports can serve concurrently as inlets to the pump. Mounting flanges (88) associated with each inlet port are adapted to connect to inlet conduits or a cap member.
