VACUUM PUMP
Refer to the Vacuum Pump Operation and Service
Manual for specific instructions.
Lubrication: We recommend that you use AEON
PD Synthetic Blower Lubricant in 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 3 times longer than a
premium mineral oil.
NOTE: AEON PD (Part #86189090 PRV NO.
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 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 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 inlets are 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.
