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.

Abstract: A fuel pump for supplying diesel fuel to an engine includes a pump housing, a motor mounted within the housing, a shaft extending from the motor, an impeller slidably attached to the shaft which has a prime number of vanes spaced unevenly about its circumference, a chamber body, and a chamber cover with a bleed orifice. The chamber body and cover form a chamber for the impeller and are held together by the housing. The chamber body and cover have pump channels of constant depth and are made of phenolic with fiberglass fill. The impeller is made of phenolic with fiberglass fill and granular fill.
