Abstract:
A multistage centrifugal pump has a rotatable shaft, a plurality of pump stages and a thrust module. Each of the plurality of pump stages has an impeller connected to the rotatable shaft and a stationary diffuser. The thrust module has a thrust runner and a unitary thrust pad. The unitary thrust pad has an axial wear face adjacent the thrust runner and a radial wear surface adjacent the rotatable shaft. The axial wear face and radial wear surface are integrated as a unitary component. The unitary thrust pad is secured to a thrust pad support with threaded fasteners that are torqued to a predetermined extent.
