Gene Vogel EASA Pump & Vibration Specialist
Vertical turbine pumps (VTP) commonly have rotors with multiple mixed-flow impellers (sometimes 12 or more) that are supported by a vertical pump motor. Such designs offer a lift adjustment for raising or lowering the pump rotor to properly position the impellers within the bowl. Depending on the type of pump, this may be critical for maximizing pump efficiency and could have a significant impact on motor load (current) and reliability. Given the importance of VTP lift adjustments, it is necessary to recognize that procedures vary with the characteristics of the pump and motor.
