ROOT CAUSE FAILURE ANALYSIS, RECONDITIONING & REINSTALLATION
The J.A.C. Pump Services root cause analysis procedure identified issues which were responsible for the chain of events leading to pump failure.
Floating pontoon pump station in dam.
Column sump pump with 90kW motor.
Oil lubricated Line shaft assembly with bearings and mechanical
Ceramic wear coatings.
Thorough investigation and condition reporting indicated the sequence of events eventually
leading to component failure. During pump reconditioning, componentry upgrade was
conducted to address the mode of failure. Additional works were performed to replace damaged
componentry and ensure realignment. Ceramic wear coatings were also utilised to bring the
pump back to specification and enhancing future performance. Full commissioning report
indicating pump performance was submitted upon reinstallation.
