Video: Changing the Shaft Seal Oil on a Leybold Booster Pump (WAU2001)

We’ve shown you how to change the front oil on a Leybold booster pump. Now, we will show you how to change the shaft seal oil on the back of the booster pump.

Chances are you have a Leybold booster pump (WAU2001) if you have a TITAN® H6 vacuum furnace. When performing an oil change on this pump, important tips to remember include:

  • Remove the oil when the booster pump is still warm or hot. This encourages better oil drainage.
  • Use a drain pan that is capable of holding at least two quarts of oil.
  • Perform other preventative maintenance activities at this time. This includes checking the condition of the gasket.
  • Avoid overtightening the gasket when closing back up.

If you have to refill the oil more than once a week, you have a leak. You should inspect the surrounding areas and call for an inspection.
