Abstract
A centrifugal pump having an adjustable clean-out assembly (), the position of which determines the face clearance between a wear plate () and an impeller (). The clean-out assembly includes an end cover () that threadedly mounts a plurality of adjustment assemblies. The adjustment assembly includes an adjuster () that defines a through bore for slidably receiving a retaining stud () that extends from the pump housing. Each adjuster includes an abutment surface () which engages a pump surface and which establishes the face clearance between the wear plate and the impeller. Each adjuster includes a hex-shaped head which is engageable by an associated locking member () secured to the end cover. Each locking member includes a locking collar () having 18 teeth which allows the collar to engage the hex-shaped head of the adjuster in 18 different postions. By knowing the thread pitch of the adjuster thread, precise rotations of the adjuster can be used to establish a precise clearance between the wear plate and impeller. Once the adjustment is made, the locking collar is secured to the end cover which enables the clean-out assembly to be removed from the pump without disturbing the adjustment.
