摘要： A motorized pump assembly includes a pump and a motor for driving the pump. The pump includes a pump housing that at least in part defines a pump chamber. The motor includes a stator, a rotor rotatable about an axis, a motor housing, and a bearing assembly. The rotor includes a motor shaft extending along the axis. The motor housing includes an endshield that at least in part defines a motor chamber in which the stator and the rotor are at least substantially received. The bearing assembly rotatably supports the motor shaft on the endshield. The pump housing and the endshield are fixed to one another and cooperatively at least in part define an overflow chamber adjacent the pump chamber. The endshield defines a drainage channel fluidly interconnected with the overflow chamber and configured to direct fluid from the overflow chamber away from the bearing assembly.

摘要： Both a catalyst feed system and a method are provided for providing a flow, of a mud-like catalyst slurry into a polyolefin reactor. The system includes a pressurized reservoir of the catalyst having an outlet, and a progressive cavity pump including a stator and a rotor. The pump stator has an inlet connected to the reservoir outlet, and an outlet leading to the polyolefin reactor. In operation, the reservoir is first pressurized to a level a little higher than the pressure of the reactor. The outlet of the reservoir is opened and the progressive cavity pump is actuated. The pressure drop generated across the catalyst slurry contained in the reservoir by the pump causes the slurry diluent to flow between the interstices of the particles of catalyst. The thick, mud-like catalyst slurry is quickly transformed into a much less viscous, syrup-like slurry that flows from the reservoir outlet to the inlet of the pump stator. The progressive cavity pump then continuously conveys the catalyst through the stator outlet and into the reactor.

摘要： An internal gear pump with a field replaceable idler is disclosed that may be used for sanitary applications. Access to the idler mainly merely requires removal of the head. Access to the seal assembly disposed at the inboard end of the pump chamber is also fast and easy as removal of the head exposes a fastener that secures the rotor to the drive shaft. Removal of this fastener enables the rotor to be removed with a standard rotor-pulling tool thereby exposing the pump chamber seal assembly, which may be cleaned, serviced or replaced as needed.

摘要： A submersible well pump assembly has a rotary pump, a motor, and a seal section coupled between the motor and the pump. The seal section has a cylindrical housing having upper and lower adapter and a shaft extending axially through the housing. A guide tube surrounds the shaft and a bellows surrounds the guide tube. A well fluid passage communicates well fluid to a well fluid chamber between the bellows and the housing. A guide tube passage extends axially within the guide tube between an interior and an exterior of the guide tube from an upper portion to a lower portion of the guide tube for communicating lubricant in the motor with lubricant within the bellows.
