11.5 Blower Lubrication
Novatec VPDB Series vacuum pumps use horiz
tally installed Gardner Denver positive displace
ment blowers.
Gardner Denver recommends and
Novatec uses:
Gardner Denver AEON PD-XD Lubrication
or approved equivalent
NOVATEC P/N
VPDB-QT
(1qt.)
or P/N
VPDB-CASE
(12 qts.)
Lubrication Guidelines
1.
Novatec model MVP series
vacuum pumps include
splash lubricated bearings
that require no grease, but both the gear and shaft
sides of the pump unit
contain oil sumps that must be maintained as part
of your lubrication and oil replacement procedures.
2.
The lubrication should be changed after initial 500
hours of operation and then after every 1500 hours.
3.
The proper level should be in the middle of the sight
gauge when the blower is not operating. DO NOT
OVERFILL OIL SUMPS or damage to the blower may
occur.
4.
The oil level may naturally rise and/or fall in the gauge
during operation, but the oil level should not fall below
the middle of the site gauge when the blower is idle.
5.
Routine “topping up” of oil levels is
NOT advised. Each
pump examination should include stopping the pump,
allowing the oil level to stabilize and then checking the
level in the sight glass windows before adding oil to
the required level.

Lubrication fill ports are located on the top of the blower.
Sight glasses are located on the side of the blower. Oil
level should be maintained up to the middle of the sight
glass when the pump is idle. Be sure to maintain oil levels
on both sides. Do not operate a pump with an insufficient
lubricant level. Do Not Overfill.
On VPDB-20, oil drains are located under the pump deck.
