Abstract: A crescent internal gear pump includes a front cover, an end cover, a ring gear and a pinion gear disposed within a gear housing in an eccentric, intermeshing relationship. The housing is disposed intermediate the front cover and the end cover. A crescent is disposed radially intermediate the ring gear and the pinion gear. The crescent partially extends into a correspondingly shaped slot in the end cover. The gear housing, the ring gear, and the pinion gear can have substantially the same thickness. A shim can be disposed intermediate the end cover and the gear housing for establishing a desired clearance therebetween.

Abstract: A self-adjusting gear pump is disclosed. The pump may be a crescent internal gear pump, a gerotor pump, or an external gear pump. The pump includes a pump housing, gear housing, first and second gears, a side plate housing with a side plate, a shim and an end plate. The side plate moves between a first position contacting the first and second gears and gear housing, and a second position contacting the end plate. The side plate is spring biased toward the first position. A method is disclosed for match grinding the crescent plate (if used), gear housing and gears as a unit to provide a uniform surface. The side plate housing and side plate are similarly match ground. Assembly method is disclosed which allows the crescent plate to be moved with respect to the gear housing so that clearances between the crescent and the gear teeth are eliminated.
Abstract translation: 公开了一种自调节齿轮泵。 泵可以是新月形内齿轮泵，齿轮泵或外齿轮泵。 泵包括泵壳体，齿轮壳体，第一和第二齿轮，具有侧板的侧板壳体，垫片和端板。 侧板在与第一和第二齿轮和齿轮壳体接触的第一位置和与端板接触的第二位置之间移动。 侧板被弹簧偏压朝向第一位置。 公开了一种用于匹配研磨月牙板（如果使用），齿轮箱和齿轮作为单元以提供均匀表面的方法。 侧板外壳和侧板同样匹配地面。 公开了一种允许新月板相对于齿轮箱移动的组装方法，从而消除了新月齿轮与齿轮齿之间的间隙。

Abstract: A pump includes a housing, a drive shaft, a centrifugal pump portion having an impeller, and a gear pump portion having first and second gears. The impeller and one of the first and second gears are mounted to the drive shaft to drive the centrifugal pump portion and the gear pump portion at the same rotational speed. The gear pump can be a crescent internal gear (CIG) pump. The drive shaft can be rotated by a magnetic drive. The drive shaft can include a longitudinal bore in fluid communication with a cavity in the magnetic drive and with a discharge of the centrifugal pump portion to circulate working fluid through the magnetic drive to cool the drive. An impeller can be coupled to an inlet of the centrifugal pump portion.
