摘要： A positive displacement fluid pump is provided. The fluid pump includes a motor and a pumping portion driven by the motor. The pumping portion includes an internal plate, an external plate including a fluid inlet and a fluid outlet, a pumping ring sandwiched between the internal and external plates, and a pumping arrangement rotatably coupled to the motor and located within the pumping ring. The pumping ring includes at least two alignment holes extending through the pumping ring in an axial direction. The internal plate and the external plate each including a corresponding number of axially-extending alignment holes, respectively. An alignment pin is provided for each of the alignment holes of the pumping ring. The alignment holes are aligned with each other, and the alignment pins are positioned in the aligned alignment holes. A method of aligning components of a positive displacement fluid pump is also provided.

摘要： A fluid pump includes an inlet plate and an electric motor. The electric motor has a shaft that rotates about an axis. A pumping arrangement is rotationally coupled to the shaft. The pumping arrangement includes an rotating element. The fluid pump further includes a thrust bearing driver including a disc-like plate having first and second faces, and two posts extending perpendicularly from the first face. The shaft has a terminal end including a pair of slots that cooperate with the posts of the thrust bearing driver. The inner gear rotor has an inner surface including a pair of slots that cooperate with the posts of the thrust bearing driver. The posts of the thrust bearing driver are received in the slots of both the shaft and the rotating element, and the thrust bearing driver is sandwiched between the shaft, the inlet plate, and the rotating element.

摘要： A positive displacement fluid pump is provided. The fluid pump includes a housing defining an internal cavity. A motor having a drive shaft that rotates about an axis is housed within the internal cavity of the housing. An internal plate is adjacent the motor and includes a central bore through which the drive shaft extends. The fluid pump further includes an external plate including an inlet in fluid communication with a suction port and an outlet in fluid communication with a delivery port. A pumping ring is sandwiched between the internal and external plates, and a pumping arrangement is located within the pumping ring and axially between the internal plate and the external plate. The pumping arrangement is rotatably coupled to the drive shaft such that rotation of the pumping arrangement by the drive shaft causes fluid to be pumped from the suction port to the delivery port.

摘要： A casing for a fluid pump is provided. The casing includes a unitary, single-piece, elongated shell having opposite first and second open ends. A circumferential bead is formed in the shell. A sleeve is received in the first open end of the shell. The sleeve is disposed between the bead and the first open end. A heat sink cap is received in the first open end and engages the sleeve. The shell includes a crimp formed at the first open end. The crimp contacts the heat sink cap and retains the heat sink cap in the first open end. The shell includes a lip formed at the second open end. A motor section and at least a part of a pumping section of the pump are encapsulated within the shell between the lip and the crimp. A fluid pump and a method of encapsulating the fluid pump are also provided.
