VACUUM PUMP
Refer to Vacuum Pump Operation and Service
Manual for specific instructions.
Lubrication: We recommend that you use AEON PD
Synthetic Blower Lubricant in the gear end of the
vacuum pump for ALL operating temperatures. AEON
PD is formulated especially for positive displacement
blower service to provide maximum blower protection at
any temperature. One filling of AEON PD will last a
minimum of 2 times longer than a premium mineral oil.
NOTE: AEON PD (Part # 05-008039) 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.
If not using AEON PD synthetic blower lubricant, use oils
with rust and oxidation inhibitors, anti-foam additives and
the viscosity’s listed on the chart on the next page.
1. Check the oil level weekly 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 chart provided on
this page as a guide when adding oil.
2. To prevent rust from building up inside the
vacuum pump (if moisture exists) we have
provided a lubrication 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 WD-
40, or a similar lubricant, for 5 seconds
while the unit is running and the vacuum
inlet is sealed. Do this at the end of each
working day.
3. Drain, flush and replace oil every 1500
hours or yearly, whichever comes first.
Change oil more frequently if inspection so
indicates. With AEON PD synthetic
lubricant, perform the oil change
maintenance every 4500 hours or every 2
years, whichever comes first.
