Abstract
The fluid end of a reciprocating pump contains a plurality of manifold cylinders for pumping fluid. The fluid end has an improved liner assembly with a shaft, a coaxial piston, and a liner with a liner seal on an outward end. The liner and seal abut an inner wall of the manifold to prevent pressurized fluid leakage between the liner and the manifold. The liner is pressed against the manifold by an adjustment mechanism which is mounted to a housing surrounding the pump. The adjustment mechanism is spaced axially away from the manifold wall and allows the liner to self-adjust to the wall without the need for a liner bushing. A support device is provided for assisting in the vertical alignment of the liner assembly prior to the liner being pressed tightly against the manifold wall.
