Abstract: A sliding vane pump is provided including a pump assembly having a housing with a fluid inlet and a fluid outlet formed therein, a lining member received in the housing defining a substantially cylindrical inner surface and a rotor arranged inside the lining member, defining a substantially cylindrical outer surface. The inner surface of the lining member and outer surface of the rotor define a working space therebetween. The pump assembly also comprises a plurality of vanes received in slots formed about the rotor outer surface. Each vane is arranged to slide in the radical direction with respect to the rotor such that an outer edge of the vane contacts the lining member inner surface, thereby dividing the working space into working chambers. Rotation of the rotor draws fluid from the fluid inlet working into the working chambers, which is ejected into the fluid outlet.

Abstract: Disclosed herein is a sliding vane pump for providing positive displacement of a fluid such as water. The pump comprises a pump assembly having a housing with a fluid inlet and a fluid outlet formed therein, a lining member received in the housing and defining a substantially cylindrical inner surface and a rotor arranged inside the lining member to rotate about a rotational axis. The rotor defines a substantially cylindrical outer surface such that the inner surface of the lining member and the outer surface of the rotor define a working space therebetween, the working space having a radial cross-sectional area which varies about the rotational axis. The pump assembly also comprises a plurality of vanes received in substantially radial slots formed about the outer surface of the rotor.
