Abstract
A fluid pump includes a pump housing; an inlet which introduces fluid into the pump housing; an outlet which discharges the fluid from the pump housing; a pump section which pumps the fluid from the inlet to the outlet; and a strainer through which the fluid passes in order to enter the inlet. The fluid pump extends along an axis and the strainer includes a straining medium configured to allow the fluid to pass therethrough while preventing foreign matter of a predetermined size from passing therethrough. The straining medium defines a strained volume with the pump housing such that the strained volume is defined radially between the straining medium and the pump housing and such that the strained volume is in fluid communication with the inlet.
