Gene Vogel EASA Pump & Vibration Specialist
Vertical motors are a common item in most EASA service centers. There are various applications for vertical motors, but most of them are mounted on vertical turbine pumps (VTPs). Vertical motors may be hollow shaft or solid shaft; the hollow shaft motors are used exclusively on VTPs and vibration is a common problem with these installations.
