General Description
The Powerex vacuum pumps are lubri-
cated-vane vacuum pumps, which can
be used for a variety of applications.
These vacuum pumps create a suction
system, designed to rid unwanted flu-
ids and/or gases from the working area.
Wasted fluids are deposited into a col-
lection tank, and the vapors are filtered
through the system and then vented
into the atmosphere.
The Powerex vacuum pumps draw the
intake gas through a suction filter
(available as a factory installed option
or may be provided by the customer), a
protective stainless steel screen, and a
built-in suction valve to fill the inlet
section of the pump (Figure 1). The
centrifugal force resulting from the
rotation of the rotor, forces the vanes
against the inner wall of the pump
body, thereby forming three chambers
leading to a succession of variable vol-
umes that create the vacuum and flow.
Rotary Vane Vacuum Pumps
Phases of Operation:
1 Suction / start of filling
2. Maximum filling volume
3. Compression and exhaust
During phase 1, oil is injected for lubri-
cation, sealing, and cooling. Prior to
injection, a portion of the oil is passed
through an oil filter to remove any
debris. The gas / oil mixture travels from
the pump body, through the exhaust
IN552600AV 2/03
PURE AIR TECHNOLOGY
valve, and to the exhaust unit where the
first stage oil separation occurs. In the
exhaust unit the exit gas velocities are
slowed and the flow directed upward so
that the largest droplets of oil are
allowed to fall back into the oil injector.
The remaining oil is removed from the
gas by coalescence in the separating fil-
ter. The gas is then discharged from the
pump and the oil is returned to body of
the pump through a trap and automatic
float valve assembly.

General Description
(Cont.)
When the pump is stopped, the suction
valve prevents the entry of air and the
transfer of oil from the pump to the
system under vacuum. Bypassing the
exhaust valve allows the body to be
brought to atmospheric pressure to
avoid oil accumulation in the body and
prevent irregular oil injection at start-
up.
Use of the air ballast system allows for
the removal of any water emulsions in
the lubricating oil.

Rotary Vane Vacuum Pumps
Installation
Several factors should be considered
when choosing a location for the vacu-
um pump. Ventilation, surrounding
temperature, available maintenance
space, and location of the work area
are all important factors.
Install the pump on a level surface in a
clean, well-ventilated room, which has
a controlled temperature. The ideal
temperature is between 50oand 86oF
(10oto 30oC). Equipment damage may
occur if the surrounding temperature is
allowed to exceed 104oF (40oC) or fall
below 32oF (0oC). Contact the factory
for installations where the ambient
temperatures may drop below 36o F.
Do not install the pump near furnaces,
boilers or other heat producing
machinery. Locate the pump away from
any piping that may radiate heat. Keep
the pump vents at least 8 inches from
any wall or obstruction.
Ensure that adequate space is provided
to maintain and service the equipment.
If the vacuum pump is housed with
other machinery, allow for proper
clearances between assemblies.

Installation (Cont.)
Place equipment as close to the work
area as possible to minimize piping
runs.
Each pump has rubber mounts to
reduce the vibrations transmitted to
the vacuum system. A flexible hose or
flexible connector should be used for
installation between the collection
tank and the pump intake.
INLET FILTRATION (available
separately)
Inlet filtration is required to prevent
solid particles from entering the vacu-
um pump. Powerex offers both paper
and polyester inline filters to 10
micron, which assure 99% particulate
free air. Certain applications such as
the pumping of solvents, alkaline solu-
tions or corrosive vapors may require
an additional carbon filter.
WIRING
Refer to the general safety manual. All
electrical hook-ups must be performed
by a qualified electrician. Installations
must be in accordance with local and
national electrical codes. Use solderless
terminals to connect the electrical
power source.
PIPING
Refer to the general safety manual.
1. Never use any piping, which is
smaller than the pump or tank con-
nection.
2. Make sure the piping is properly
placed to reach the pump connec-
tions. Ensure that the piping is not
strained or twisted during assembly
or after final hookup.
3. Anchor piping supports separately
from the pump to reduce noise and
vibration.
4. Install flexible hose or properly
designed bends at the vacuum
pump inlet and outlet to avoid
stresses caused by vibration and/or
temperature changes.
Operation
BEFORE STARTUP
1. Make sure all safety warnings,
labels and instructions have been
read and understood before contin-
uing.
2. Remove any shipping materials,
brackets, etc.
3. Confirm electric power source and
ground have been firmly connected.
4. Be sure all vacuum and/or pressure
connections are tight.
5. Ensure all fuses, circuit breakers, etc,
are properly sized.
6. Maker sure an inlet filter is present
and properly installed.
7. Close the tank drain valve.
8. Verify the pump has the proper oil
level.
9. Visually inspect the rotation of the
vacuum pump. If the rotation is
incorrect, have a qualified electri-
cian correct the motor wiring.
STARTUP AND OPERATION
1. Follow all procedures under
“Before Startup” before attempt-
ing to operate the vacuum pumps.
2. Switch on the electrical power
source and apply power to the sys-
tem.
3. Open the tank inlet valve complete-
ly.
4. Check for excessive vibration,
unusual noise or leaks during opera-
tion.
5. Close the tank inlet valve complete-
ly.
6. Check the vacuum gage to insure
that the designated vacuum setting
is reached.
Switch the power breaker to OFF if the
vacuum pump is not going to be used
right away. If the vacuum pump is
going to be out of use for 3 months or
more, see “Long Term Shutdown”
LUBRICATION
Check lubricating oil level before each
use. Refill as necessary using only
Powerex recommended oil. See
Maintenance section, Oil Change for
listing.
GAS BALLAST
A gas ballast device is provided on all
pumps to rid water emulsion in the
lubrication oil. The gas ballast is a quar-
ter turn ball valve located under the
metal shroud directly behind the intake
flange. To access the gas ballast valve,
turn the pump to OFF, remove the two
screws holding the small access plate in
place and remove the plate, open or
close the gas ballast valve as needed,
reinstall the plate, turn the pump to
ON.
Before using the gas ballast, allow the
pump to reach normal operating tem-
perature by running without load for
approximately 10 minutes. Open the
gas ballast valve (see procedure in pre-
ceding paragraph). Remove condensate
from the lubricating oil by operating
the vacuum pump for 30 minutes with
Rotary Vane Vacuum Pumps

Operation (Cont.)
the gas ballast valve in the open posi-
tion. Close the gas ballast valve.
NOTE: When operating the pump with
highly condensable vapors, open the
intake slowly after the pump operating
temperature has been reached to avoid
excessive condensation. Do not stop
the pump for different cycles. Close the
intake valve and allow the pump to run
at maximum vacuum with the gas bal-
last open.
LOW OIL LEVEL SWITCH (optional)
The low oil level switch is an electric
safety device, which will stop the vacu-
um pump from running when the
lubricating oil level is too low for effi-
cient operation. The low oil level kit,
available from Powerex, includes this
switch and a delay timer.
To install the low oil level switch:
1. Drain the oil from the vacuum
pump.
2. Remove the plate containing the
sight glass.
3. Replace with the plate containing
the oil level glass.
4. Install a delay timer on the low oil
level switch to avoid that nuisance
tripping. The time delay should be
set so that the low oil condition is
continuous for 10 seconds before
the alarm actuates and locks itself
in. A typical low oil level circuit is
shown below.
5. Refill the unit with oil.
Maintenance
3,000 HOURS
OIL CHANGE
Disconnect unit
from power source
and release system vacuum before
attempting to install, service, relocate
or perform any maintenance.
NOTE: Certain pumping applications
pollute the oil more than others. Only
experience allows for the correct deter-
mination of oil change intervals, and
the choice of oil quality. Powerex sug-
gests that you change the oil in the
pump at 3000 hour intervals when
using Shell Corena 46. Powerex also
suggests that you change the oil at
least once per year.
Before draining oil, remove the oil fill
Cam, and then remove oil drain cap to

release any trapped air.
1. Place a suitable container for used
oil under the drain valve and open
the valve.
2. Allow all oil to drain from the
pump and then close the drain
valve and replace the oil drain cap.
3. Refill with one of the recommend-
ed lubricants listed below:
a. OEM supplied type - Shell

Maintenance (Cont.)
OIL SEPARATING CARTRIDGE
The speed at which the separating car-
tridge gets soiled depends on the
quantity of impurities sucked into the
vacuum system. These cartridges are
not reusable. Replacement is recom-
mended at 3000 hour intervals.
Excessive soiling of
the separating fil-
ter will lead to an increase in exhaust
pressure, reducing your available vacu-
um levels. The flow will diminish, while
the motor current and pump tempera-
ture will increase. The cartridge can
split and the pump will emit fumes
through the exhaust.
To replace the oil separating cartridge:
(Refer to Figure 6.) Remove the nuts
(1) and plate (2) with its gasket.
Unscrew (3) so as to release and
remove the stirrup assembly (5).
Remove and replace the oil separating
cartridge (6).
To reassemble: Position the tip of the
cartridge correctly in the exhaust unit
recess so that the O-ring (7) bears
against face (A) of the recess. Reinstall
stirrup assembly (5) and screw in (3) in
order to push O-ring (7) up against
face (A). Once the new cartridge(s) is
(are) installed, before putting back on

the closing plate (2) and if the applica-
tion so permits, start up the pump to
ensure there are no fumes. If fumes are
emitted, the cartridge is not correctly
positioned: O-ring (7) is not bearing
correctly against face (A). Adjust the
installation of the cartridge. Reinstall
plate (2) with its gasket. Retighten the
nuts (1).
NOTE: Vacuum levels of less than 12
in./Hg sustained for more than 10 min-
utes will cause oil passage downstream
of the coalescing filter(s).
3,000 HOURS
AIR FILTER
The rate of clogging of any air filter is
dependent upon the amount of impu-
rities being sucked into it. Changing air
filters every 3000 hours is recommend-
ed along with an oil change. This inter-
val may need to be lowered in applica-
tions when a large amount of impuri-
ties are present. Clean the inside of the
filter housing when the filter is
changed.
Do not allow any
dust or debris to
fall into the canister when changing
the filter or cleaning the filter housing.
When filter has been changed, observe
the pump for the first several minutes
of operation to verify that vacuum lev-
els are correct.
SUCTION SCREENS
Refer to Figure 7.
There are two screens, (1) and (2), at
the pump suction inlet. They have to
be cleaned regularly by washing or
blowing, depending on the amount of
impurities sucked in. Replace them if
necessary.
Assembly instructions: Remove the suc-
tion inlet flange (3). Remove and clean
screen (1). Remove the mating flange
(4). Remove and clean screen (2).
10,000 HOURS
COUPLING
The coupling ring is subject to wear
that relates to the service conditions
(number of start/stop cycles, tempera-
NOTICE
Figure 8 - Shaft seals
Figure 9 - Gas ballast
ture, etc.). Check the condition of the
coupling ring and fingers of the 1/2
sleeves that accommodate the ring. If
necessary, replace them by removing
the electric motors.
10,000 HOURS
SHAFT SEALS
(Refer to Figure 8.) The rotor shaft out-
lets are sealed by shaft seals. These
seals are subject to wear that depends
on the service conditions. This wear can
be characterized by two phenomena:
oil leakage or reduction in the final
vacuum.
These shaft seals (1) rub against a wear
ring (2). If you have to replace the
wear ring (2), replace the O-ring (3) at
the same time.
Assembly instructions: For the front
plate: remove the motor assembly,
remove the rotor shaft coupling 1/2
sleeve. Remove the front plate. Check
the condition of wear ring (2), replace
it or shift the shaft seal. Remove the
shaft seal (1) and fit a new one using a
tool that ensures its perpendicularity
with respect to the rotor axis. The main
shaft is directed towards the interior of
the body. Reinstall the assembly.
For the rear plate (except E25) :
remove the fan assembly, remove the
rear plate and proceed as before.
3,000 HOURS
GAS BALLAST FILTER
(See Figure 9.)
The gas ballast has an air filter that has
to be replaced every 3000 hours. To
replace the filter, disconnect and lock
out power from the pump. Remove
the gas ballast cover plate. Remove
the PVC cover (1) and replace the filter
element (2). Replace the cover and the
cover plate.

Notes
Maintenance (Cont.)
AUTOMATIC TRAP
(See Figure 10.) Reminder: This trap
re-injects the oil from the separating
cartridge into the pump. It is located in
the separating cartridge compartment
(see Figure 6, Item 8).
Checking operation: Stop the pump.
Remove the cap and trap assembly, giv-
ing access to the compartment of the
separating cartridge(s). Add 1/4 L of oil
to the trap. The float should rise. Start
up the pump. Replace the cap and trap
assembly. The 1/4 L of oil should be
sucked in. When this happens, the level
in the separating cartridge(s) compart-
ment will drop.
15,000 HOURS
REPLACING VANES
(See Figure 11.) Remove the shroud
cover from the pump. Remove the
cooling system on pumps 3 HP and
larger. Then remove the rear plate end
cap opposite the motor side. Replace
the vanes one by one, taking care to
position the vane chamfer correctly.
(See Figure 11.)
LONG TERM SHUTDOWN
If the vacuum pump is to remain out of
service for an extended period of time
(3 or more months) or is not going to
be put into service until a later date,
empty the pump of oil, fill it with rust
inhibiting oil, run it for 10 minutes, and
then drain off the rust inhibiting oil.
Blank the openings with adhesive tape,
and then store the pump in a dry place.
The pump must not be stored in a
place that is damp and/or subject to
large temperature variations.
