SELF-ALIGNING MOUNTING AND RETENTION SYSTEM

摘要

A clamp is secured to a displacement pump, and the clamp includes an axial ring and a tightening ring. The axial ring is mounted above the tightening ring, and the axial ring is configured to align the displacement pump during mounting and to limit the stoke of a pump rod within the displacement pump. The tightening ring may be tightened such that the axial ring and the tightening ring exert a clamping force on a drive housing, which secures the displacement pump to the drive housing. The tightening ring may receive a projection extending from the drive housing to provide structural support to the drive housing.

主权项

1. A clamp for a displacement pump, the clamp comprising:
an axial ring fixedly mounted on an exterior of the displacement pump proximate a pump rod extending from the displacement pump; and a tightening ring mounted on the exterior of the displacement pump below the axial ring; wherein a gap is disposed between the axial ring and the tightening ring, and the tightening ring is movable such that the axial ring and the tightening ring may exert a clamping force on an object disposed within the gap.
