Pacific Coker Jet for Refinery
Application: Coker Jet for Refinery
Pump Details: Pacific 3” S-A-TB
Pump Type: Barrel
A refinery sent their problem pump to Hydro for repair. Hydro’s thorough inspection revealed very serious problems and a comprehensive workscope was developed and approved by the refinery.In addition to restoring the fits and tolerances of the rotor to their optimum specifications, Hydro also proposed several upgrades to improve the reliability and performance of the pump. These upgrades included re-establishing the centerline compatibility of the rotor, manufacturing a new, larger shaft for improved rotor stability, manufacturing new wear parts, using precision split rings, and investment cast impellers.
Once installed, the rebuilt pump exhibited very low vibration and produced the same performance at 4000 rpm as the pump in its previous condition at 4400 rpm. In addition to saving the refinery thousands of dollars in repair, downtime, and energy costs, Hydro has been informed by the refinery that it is now their "best running pump."
