Maintenance
Vacuum Pump
Refer to the Vacuum Pump Operation and Service
Manual for specific instructions.
Lubrication: We recommend that you use Tuthill
Pneulube synthetic lubricant. Tuthill Pneulube
synthetic lubricant is formulated especially for Tuthill
rotary positive displacement blower service to provide
maximum protection for all operation temperatures
NOTE: Tuthill Pneulube synthetic lubricant is the oil
which PROCHEM puts in the vacuum pump at the
factory. Topping off or adding petroleum oil to
synthetic oil is NOT recommended.
1. Check the oil level daily to assure the proper level.
PROPER LEVEL cannot be overemphasized. Too
little oil will ruin bearings and gears. Too much oil
will cause overheating. Use the illustration as a
guide when adding oil.
2. To prevent rust from building up inside the vacuum
pump (if moisture exists) we have provided a lubri-
cation cup on the front of the unit.
First run the unit at least 1 minute to remove any
moisture from the vacuum pump. Next, fill the
lubrication cup with water displacing lubricant, for
5 seconds while the unit is running and the vac-
uum inlets are sealed. Do this at the end of each
working day.
3. Drain, flush and replace oil every 1000 hours or
yearly, whichever comes first. Change oil more
frequently if inspection so indicates.
Vacuum pump oil capacity is approximately 10.5
ounces.
4. Vacuum pump lubrication is vital to performance of
our pump. Failure to follow the maintenance
schedule in the “Maintenance Schedule” can lead
to permanent damage to your blower.

Manual for specific instructions.
