Abstract
A pump (10) for providing water from a source to a remote location includes a casing (11) which receives the water through an inlet port (22) which is provided to the remote location through a discharge port (20). An impeller (30) in the casing (11) is rotated by a motor (23). A diffuser (35) is positioned adjacent to the impeller (30) and has a shoulder (42) facing the inlet port (22). A nozzle (44) is mounted in the inlet port (22) to receive low pressure water from the source which is transmitted to a venturi tube (43) positioned between the diffuser shoulder (42) and the front wall (16) of the casing (11). The venturi tube (43) directs water to the impeller (30) and diffuser (35) which provide water at high pressure, upon demand, through the discharge port (20) and also recirculates high pressure water in the casing (11) to the venturi tube (43) through openings (51) in the wall thereof.
