Abstract
Aspects of the present invention relate to a stator component for a pump housing. The stator component has a plurality of fluid inlet channels for conveying fluid to respective pumping chambers. The fluid inlet channels each have an inlet port for conveying fluid into the pumping chamber. A plurality of fluid transfer channels are provided for conveying fluid to a respective one of the fluid inlet channels. The fluid transfer channels each have an inlet for receiving pumped fluid. The stator component is adapted to receive at least one sealing member for inhibiting the conveyance of fluid into an associated one of the pumping chambers. Aspects of the present invention relate to a pump housing, a cover plate and a pump. Aspects of the present invention also relate to a method of converting a stator component.
