Abstract
A piston pump includes a frame, a housing configured to be coupled to the frame via a fastener, an annular liner defining a chamber configured to receive a piston of the piston pump, and an annular liner lock flange circumferentially surrounding the annular liner. The annular liner lock flange includes a radially-extending portion configured to be positioned within a respective counterbore of the frame and a respective counterbore of the housing while the housing is coupled to the frame via the fastener to block relative movement between the liner lock flange, the frame, and the housing.
Claims20
A piston pump, comprising:
- a frame;
- a housing configured to be coupled to the frame via a fastener;
- an annular liner defining a chamber configured to receive a piston of the piston pump;
- and
- an annular liner lock flange circumferentially surrounding the annular liner and comprising a radially-extending portion configured to be positioned within a respective counterbore of the frame and a respective counterbore of the housing while the housing is coupled to the frame via the fastener to block relative movement between the liner lock flange, the frame, and the housing.
A method of assembling a piston pump, comprising:
- positioning a radially-expanded portion of an annular liner lock flange within a respective counterbore of a frame;
- positioning the radially-expanded portion of the annular liner lock flange within a respective counterbore of a housing;
- and
- subsequently coupling the frame to the housing using a fastener, thereby blocking movement of the annular liner lock flange relative to the housing and the frame.
A liner assembly for a piston pump, comprising:
- an annular liner defining a chamber configured to receive a piston of the piston pump;
- an annular liner lock flange configured to circumferentially surround the annular liner;
- an annular liner lock nut configured to circumferentially surround the annular liner and to couple to the annular liner lock flange, wherein the annular liner lock flange and the annular liner lock nut are configured to engage the annular liner to block movement of the annular liner relative to the annular liner lock flange and relative to the annular liner lock nut;
- and
- an annular wear plate configured to be positioned between the annular liner and a housing along an axial axis of the liner assembly, wherein the annular wear plate is movable through the annular liner lock flange.
