Abstract: A pumping apparatus includes a housing having an inlet at a first end and an outlet at an opposite second end. An encapsulated stator defines an opening and is supported by the housing. A pressure plate includes diffuser vanes formed as part of the pressure plate. The pressure plate is formed as part of the encapsulated stator. A rotor is positioned at least partially within the opening and is rotatable with respect to the stator and an impeller is coupled to the rotor and cooperates with the pressure plate and the housing to pump a fluid from the inlet to the outlet in response to rotation of the rotor.

Abstract: A pump has a housing that defines a pump chamber (200) with a fluid inlet and outlet (26, 28). An impeller (30) is mounted for rotation in the pump chamber. A raceway (40) is in floating axial relationship with the impeller and divides the pump chamber into an inlet chamber (202), an impeller chamber (204) and a discharge chamber (206). The raceway has preferably two flow channels, in separated end-to-end arrangement. Each flow channel has an inlet passage and an outlet passage, establishing a fluid conduit from the inlet chamber to the impeller chamber and then to the discharge chamber. A spring (60) provides resistance to axial movement of the raceway away from the impeller. A seal chamber (42) formed on the raceway and pressurized by the fluid, urges the raceway towards the impeller.

Abstract: A break-away fitting facilitates installation and removal of a pump in wet well system, along at least one guide rail. When installed, the fitting mates an outlet of the pump to an outlet pipe of to wet well. The fitting has a body with a first and a second surface, the surfaces arranged to be substantially perpendicular to each other. A flanged opening in the first surface is sized and adapted for attaching the body to the outlet flange of the pump. The second surface has indentations for engaging the at least one guide rail, so that the body slides in the vertical channel. To minimize the dangers from static electricity in the wet well, the body may be formed from a non-sparking material, such as brass or bronze, or a surface of the indentations may be covered by a non-sparking material, including high-density polyethylene or poly(tetrafluoroethylene).

Abstract: An electric motor includes a stator, a housing supporting the stator and having a bearing seat with an inner surface and an inner end, a bearing having an outer surface, a shaft rotatably supported by the bearing, and a rotor supported by the shaft. The motor also includes a tolerance ring having an interior surface, an exterior surface disposed against the bearing seat inner surface, and a plurality of elastic corrugations. Each of the elastic corrugations projects radially from the interior surface, defining a shoulder section disposed between the bearing and the inner end of the bearing seat. The shoulder section generates a spring force against the bearing to axially and radially support the bearing and to axially preload the bearing.

The motor assembly also comprises a fan mounted on the rotating shaft, the fan operable to generate an air flow of ambient air through the at least one air inlet aperture, the at least one air passage and the at least one air outlet aperture.

Abstract: A terminal board includes an attachment portion engageable with an end cap and defines an attachment plane that is substantially parallel to an end plane defined by the end cap, and a first terminal portion adapted to receive a first terminal wire. The first terminal portion defines a first terminal plane that intersects the end plane to define an included angle. The included angle is between about 40 degrees and 80 degrees.

Abstract: An apparatus comprising a driven element, a driving element operably coupled to the driven element, and a shield coupled to the driving element such that the shield at least partially covers at least one of the driven element and the driving element. The driven element includes a housing with an outer surface. The outer surface has a first raised portion and a first non-raised portion, the first non-raised portion at least partially surrounding the first raised portion, the first raised and first non-raised portions define a first surface pattern. The shield has an outer surface with a second raised portion and a second non-raised portion. The second non-raised portion at least partially surrounds the second raised portion, defining a second surface pattern substantially similar to the first surface pattern.

Abstract: An electric motor having an integrally formed bonding apparatus that allows an installer to quickly and efficiently bond the electric motor to a bonding grid of a bonding area. A fastener having a head is inserted into an aperture of the housing of the electric motor such that a bonding conductor is captured between the housing and the head. The bonding conductor is electrically coupled to the housing via direct contact between the bonding conductor and the housing and/or via indirect contact through the fastener. An integrally formed surface of the housing prevents the bonding conductor from moving out from under the head.

Abstract: A method of assembling a motor and pump assembly. The machine or pump assembly includes an electric motor having a housing, an end frame and a bolt extending through the housing and the end frame to secure the housing and the end frame together. The end frame includes a through-bore having an inner diameter. The bolt has a major diameter that is greater than the inner diameter of the through-bore so that when the bolt is turned into the through-bore, the bolt creates threads in the through-bore of the end frame. When the electric motor is placed next to the housing, the bolt is turned to strip the threads in the through-bore and screw the bolt into the housing of the pump apparatus.

The clip is mounted to the end frame without the use of any other common fasteners. The cord is captured between the clip and the end frame such that the resilient spring tab engages the cord to relieve stress or strain on the internal junction end.

Abstract: A scroll type fluid handling apparatus, such as a refrigeration compressor, has co-rotating driver and idler scroll members supported for rotation about offset, generally parallel axes. The idler scroll member has a support shaft which is supported on the compressor housing by a pivot bushing having an eccentric pivot axis which permits radially compliant movement of the idler scroll along a line of action which is predetermined to provide a component of a resultant force acting between the scroll members which will urge the idler scroll wrap into engagement with the driver scroll wrap under a wide range of operating conditions to enhance the contact line seal between the scroll wraps.
