  • Rotor shaft hub and bearing for a high pressure fluid pump assembly
    Patent number: 12247565
    Abstract: Disclosed is a hub and a bearing which cooperate to hold a shaft in steady axial alignment with a rotor. In a preferred embodiment, the shaft is coupled to the rotor of a fluid gear pump. The gear pump is located in a pump assembly between a front cover and a rear casing. A hub receiving pocket is formed in the front cover, and the hub is connected to the front cover for receipt within the hub receiving pocket. The bearing is surrounded by the hub such that the shaft runs through the bearing to be coupled to the rotor of the gear pump. A pair of high pressure seals are located within the hub at which to surround the shaft and prevent leakage. The bearing being surrounded by the hub stabilizes the shaft to minimize wobbling in response to axial and radial loads to which the shaft is subjected while rotating.

  • Gear pump
    Patent number: 8118579
    Abstract: A pump comprises a driving rotor and a driven rotor that are positioned in a housing such that, as the driving rotor and the driven rotor rotate, the teeth of the driving rotor and the teeth of the driven rotor mesh to form a positive displacement seal. The teeth of the driving rotor and the driven rotor are configured such that seals between the inlet side and the discharge side of the pump are formed between only the leading surfaces of the teeth of the driving rotor and the trailing surfaces of the teeth of the driven rotor.
