What to do if my Eaton Vickers 25V Water Pump system is not developing pressure?
- A
  Amy GillAug 13, 2025
  If your Eaton Water Pump is not developing pressure, it could be due to several reasons. The relief valve might be open, in which case it should be repaired or replaced. There could be a loss of fluid internally, indicating slippage, which requires evaluation and repair. Ensure the cartridge kit is assembled correctly and for the proper rotation; reassemble it if necessary. Check that the pump inlet and outlet lines are correctly connected, and replumb them if reversed. Finally, inspect the drive mechanism for any disconnections or breaks and repair them.

Why is my Eaton Vickers 25V Water Pump making excessive noise?
- B
  Benjamin SchmidtNov 4, 2025
  If your Eaton Water Pump is making excessive noise, several factors could be the cause. It might be due to a low oil level in the reservoir, so ensure you fill it to the correct level with the recommended fluid. Air in the system could also be the reason; try opening the reservoir cap and operating the system until the air is purged, and bleed the hydraulic lines at the highest point downstream while the system is under pressure. Check the inlet line and fittings for any air leaks that could be causing a vacuum condition. Ensure the correct type of oil is used, as oil that is too thick can also cause noise; warming up the pump in cold weather might help. Damaged or missing pump seals at mating surfaces can also be a culprit, so locate and replace any that are faulty. Additionally, verify t...
