    Abstract: A fuel pump includes a pump housing with a motor which is adapted to rotate a shaft with a ring impeller mounted thereon. A bottom is mounted to the housing and has an outlet. A cover is mounted on an end of the housing and is attached to the bottom with the ring impeller enclosed between the cover and the bottom. The cover includes a first side having a fuel inlet orifice and a second side having a flow channel formed therein. The inlet orifice extends through the cover in fluid communication with the flow channel. The flow channel includes an inlet, a ramp, a ramp end and a main channel. The inlet includes a smooth curved profile. The ramp connects the inlet to the ramp end. The ramp end connects the ramp to the main channel.

    Abstract: A pump includes a pump casing and an impeller. The pump casing has an axis and comprises a cover having a face surface and a body positioned about the axis. A channel is defined in the face surface of the cover. An inlet opening extends through the cover and is coupled to the channel. The channel has a first section and a second section. The first section extends from the inlet opening and is continually sloped relative to the face surface of the cover. The first section has a length of about 40 to about 90 degrees, as measured circumferentially on the face surface of the cover about the axis. The first section includes an inlet ramp, a main ramp, and a secondary ramp, with the secondary ramp being positioned between the main ramp and the inlet ramp, and the inlet ramp being positioned adjacent the inlet opening. Each ramp has at least one depth and at least one slope.
