- Most pumps work in abrasive environments, and when they slow in
discharge or seize they cause high maintenance and shut-down
time.
- Our methods of repairing pumps, housings, and impellers have
proven very successful.
- First, we determine the degree of damage and may need to
fabricate parts too damaged to repair. Second, we evaluate the
pump, housing, and or impeller for hard coating. We
apply tungsten carbide to only the areas most effected by your
specific slurry.
- The pump housing normally is clad as follows: water
passage, cut-water, inlet, discharge, case-ring, and face.
- The backplate face is an area of wear and potential failure, this
area is easily clad with tungsten carbide.
- The impeller is usually, but not always clad in the following
areas: inlet face, diameter next to case ring, discharge
ports, front and back leading edges.
