Union Control Rod Drive
Application: Control Rod Drive
Pump Details: Union 2x3 MNB 10-Stage
Pump Type: Multi-Stage Horizontal Split Case
Many control rod drive pumps exhibit high vibration, premature opening of wear components, and accelerated erosion of the casing. By applying our stringent repair standards and practices, Hydro has been able to significantly improve pump performance so pump efficiency can be maintained over a longer period of time.
Hydro's upgrade package for control rod drive pumps includes ensuring concentricities and perpendicularity within 0.0015", performing rotor centralization, balancing to 1 W/N, and upgrading the casing to withstand fluid velocities without erosion.
