Pacific Centrifugal Charge
Application: Centrifugal Charging Pump
Pump Details: 2.5” Pacific RL IJ 11-Stage
Pump Type: Barrel
In 2006, HydroAire was asked by a major nuclear utility to manufacture a new casing and discharge head for a 2.5" RL IJ centrifugal charging pump. The pump element installed in the new casing had been previously built by HydroAire and kept in storage.
HydroAire's design improvements include modified hydraulic design to meet a much more narrow performance band, an improved shaft design to reduce stress concentration, optimized A & B gap to eliminate axial shuttling and vane passing vibration, and interference fit for covers and impellers to improve rotor stability and balance, which further improves stator rigidity and alignment.
HydroAire has had a long-lasting positive relationship with this nuclear power plant. When HydroAire was finished with this pump, the plant was so pleased with our work that they placed additional orders.
HydroAire has manufactured five new RL IJ centrifugal charging pump casings and upgraded rotors for this utility, having shipped one in 2007 and one in 2008. The third will ship in 2009 and two are scheduled for delivery in 2010.
