摘要： 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.

摘要： An electrically surge protected motor (13) includes a housing (14) which when in a fluid is in communication with electrical ground. The motor (13) has an end ring (17) in contact with the housing (14), stator windings (15) within the housing (14), and power wires (21) which provide electrical power to the windings (15). A surge suppressor (23) is electrically connected between each power wire (21) and the end ring (17) and includes a gas filled chamber (31) within which are spaced electrodes (27). One of the electrodes (27) is electrically connected to the power wire (21) and the other electrode (27) is electrically connected to the end ring (17). The conductivity of the gas in the chamber (31) is such that at a predetermined voltage level in the power wire (21), electrical current will be diverted from the windings (15), pass through the chamber (31) between the spaced electrodes (27), and thereafter pass to ground through the motor housing (14).
