Replenishing The Lubricating Fluid - EBARA 80?25 Installation Operation & Maintenance

EBARA Multi-Stage Dry Vacuum Pumps
CAUTION
!
Be sure to use the outer most plugs. On all pump models, a second plug is
located on the inner flange. This is not a fill plug and should not be removed
to add lubricating fluid to the pump.
3. Place at least a 1 liter or 1quart capacity container below the drain plug for
the secondary reservoir.
4. Remove the drain plug from the secondary reservoir. Allow the lubricating
fluid to drain for several minutes to ensure sufficient drainage.
5. Check and clean the O-ring on the drain plug. Replace the O-ring if it is worn
or damaged.
6. Replace and tighten the drain plug for the secondary reservoir.
7. Place the container for the used lubricating fluid under the drain plug for the
primary reservoir.
8. Remove the drain plug from the primary reservoir. Allow the lubricating fluid
to drain for several minutes to ensure sufficient drainage.
9. Check and clean the O-ring on the drain plug. Replace the O-ring if it is worn
or damaged.
10. Replace and tighten the drain plug.
11. Remove the used lubricating fluid. Be sure to dispose of this lubricating fluid
properly.
The pump is now ready for fresh lubricating fluid. At this point the sight glasses can
removed and cleaned if necessary. (See "Cleaning the Sight Glass".)
12. Pour the lubricating fluid into the fill port while viewing the level on the sight
glass. Add lubricating fluid to slightly above the upper limit line.
13. Check and clean the O-ring on the fill plug. Replace the O-ring if it is worn or
damaged.
14. Replace and tighten the lubricating fluid fill plug.
