ABSTRACT:
A pump casing comprises an inlet conduit, a volute and a flow directing chamber. The inlet conduit has a first interior cross-sectional area. The volute has a hollow interior adapted to house a pump impeller. The flow directing chamber is positioned intermediate the inlet conduit and the volute. The chamber has a second interior cross-sectional area greater than the first interior cross-sectional area. The chamber has an inlet opening at a lower portion of the chamber and an outlet opening at an upper portion of the chamber. The inlet opening is in fluid communication with the inlet conduit. The outlet opening is in fluid communication with the volute. The outlet opening has a third interior cross-sectional area less than the second interior cross-sectional area. In another aspect of the pump casing, the inlet conduit has an upstream opening and a downstream opening and is adapted for directing a flow of fluid along a generally longitudinal linear first flow path from the upstream opening to the downstream opening. The outlet opening of the chamber is laterally offset from the first flow path. The chamber includes a front wall adjacent the inlet opening and a generally cylindrical peripheral wall extending from the front wall toward the volute. The front wall and peripheral wall are adapted to direct the flow of fluid received from the inlet conduit toward the outlet opening of the chamber along a generally linear second flow path that is generally parallel to the first flow path.
