What to do if my Eaton Vickers V-138X-E-20 is not delivering fluid?
- A
  aburnsAug 16, 2025
  If your Eaton Water Pump isn't delivering fluid, several issues could be the cause. First, the pump might be driven in the wrong direction; immediately reverse it to prevent seizure and check the drive rotation against the arrow on the pump body. Other potential causes include a broken drive shaft or sheared shaft key, a blocked fluid intake pipe, air leaks at the intake, a low oil level, or vanes stuck in rotor slots. Check each of these possibilities, and take corrective actions such as replacing damaged parts or adding new fluid of the proper viscosity.
