摘要
A submersible pump assembly having a volute casing in which a pump impeller is rotatably driven from a power source located outside the pump casing. The scroll-type casing has an axially directed inlet and tangential outlet. A drive shaft connects the power source with the radial flow impeller and a support bearing for the drive shaft is located at one side and centrally of the casing. The water inlet for the pump casing is located co-axially with the axis of the impeller at one side of the pump casing. The water flowing in an axial direction into the pump casing forms a vortex around the shaft bearing to create a minimum pressure zone around the bearing.
