    Abstract: The present invention discloses a vacuum water pump wherein an impeller (14) that is divided into a suction portion (16) formed in such a manner as to be in close contact with the inner peripheral surface of a tapered cover (8) and a discharge portion (17) coupled to a main body (6) side are mounted inside a pump chamber (10), thereby having excellent vacuum suction, while exhibiting a low output resistance and having optimal discharge pressure, and a suction pipe (11a) and a discharge pipe (13a) are disposed at a higher position than the pump chamber (10), thereby always keeping the water fully filled in the pump chamber (10), without discharging to a suction opening (7) such that the water pump can conduct good pumping when it is re-activated, without any separate vacuum process.

    Abstract: A two-stage sewage grinder pump (10) having two impellers (30, 32) and a grinder (60) attached to the motor shaft (24). Preferably, both impellers are vortex impellers and are positioned between the grinder and the motor. The motor housing includes a discharge conduit (70) that is monolithic with the motor housing (20). An anti-siphon valve (71) is integral with the discharge conduit. An integral discharge flange (75) and check valve (78) are attached to the discharge conduit to connect the sewage grinder pump to a sewage out­let.

    Abstract: A centrifugal pump (10) including a motor (12) connected to a volute housing (14). The volute housing is configured to receive a pumping mechanism that includes an impeller (26) rotatably connected to the motor. At the impeller suction side the volute housing includes a wear plate (40) and a snap ring (54). The volute housing may also include a removeable cover (58) that provides access to the interior of the volute housing and to components of the pumping mechanism. In one exemplary embodiment, the removeable cover is connected to the volute housing by fasteners, such as bolts (66). By removing the cover, the impeller, wear plate, and other components of the pumping mechanism may be disassembled and, if necessary, serviced, without the need to remove the motor from the volute housing. In another exemplary embodiment, a gasket (56) having an integrated flapper valve (60) is secured between the cover and the volute housing. The flapper valve is positioned to align with a fluid inlet formed in the cover and acts as a check valve, substantially preventing fluid within the volute housing from exiting through the inlet (62).

    Abstract: A modular header body is described for distributing fluid to an individually pumped fluid circuit. The modular header body has a valve to selectively isolate the header body's suction chamber from its volute, which permits a pump motor to be disconnected from the header body while the valve is closed. Each modular header body is constructed so that adjacent header bodies can be connected to each other to form a common suction chamber. Each header body's isolation valve operates independently so that the volute of one header body can be isolated from the common suction chamber without affecting fluid supply to the other header bodies.
