INITIAL START UP OF ProVac 3 PUMP
Congratulations on your purchase of a Conde ProVac 3 pump. You have selected the finest and most
innovative vacuum pump available. Conde designs and builds pumps for long life, durability and ease of
use.
SAFETY INFORMATION
WARNING: The vacuum pump has rotating parts. Keep guards in place. Never operate the pump
with the guards removed.
WARNING: The vacuum pump may reach temperatures above 200 degrees F during extended or
severe duty operation. Allow to cool before servicing.
CAUTION: Never operate without oil. Failure to properly lubricate the pump will cause premature
failure.
CAUTION: The pump will discharge oil from the exhaust port. Connect the exhaust port to an ade-
quate oil recovery system.
IMPORTANT
Vacuum relief valves have NOT been pre-set.
(These should both be adjusted after the pump is installed)
To adjust vacuum relief valve
1) If the pump is equipped with the slide valve diverter valve, pull the handle out to engage in
the vacuum mode.
2) Close all openings in the vacuum system.
3) Start pump.
4) Loosen jam lock nut on top of the relief valve.
5) Under the jam nut is the adjustment nut. Turn nut clockwise to increase vacuum, turn
counter-clockwise to decrease vacuum.
6) After desired vacuum is reached, re-tighten jam lock nut.
CAUTION: DO NOT EXCEED 20” HG FOR CONTINUOUS OPERATION
CONDE WICK OILING SYSTEM
All Conde ProVac 3 pumps are equipped with the trouble free and adjustment free Conde Wick Oiling
System. The Conde Wick system has been engineered to provide constant oiling to your vacuum pump
under all operating conditions. There is never any need for adjustment of any kind. No more fooling
with tricky drip oilers.
Before operating your pump, fill the oil reservoir with a premium quality 10W-30 grade high detergent
synthetic motor oil. After taking delivery of your pump, make sure that the oil reser-
voir is filled. Pumps are not shipped with oil in the reservoir. Fill the tank until it is just
below
The level of the tank jets in the inside of the reservoir. All tank oilers are equipped with a sight glass to
determine the oil level inside the tank.

OIL RECOMMENDATIONS
Use high detergent 10W-30 motor oil only. Synthetic oil is highly recommended and will extend the
life of your pump. Using the proper type and weight oil is essential for long life and trouble free opera-
tion. Using the wrong oil or dirty oil can cause loss of vacuum or pump failure. Never run the
pump without oil in the tank oiler. Running the pump without oil in the reservoir
will cause pump failure!
Changing the oil is not necessary since the oil is discharged from the pump and should be properly dis-
posed of.
Check the oil level daily or every 8 hours of operation.
Any oil catch devises used with the pump unit should be periodically drained to avoid oil being blown out
the exhaust. This used oil should not be re-used.
GENERAL MAINTENANCE
If pump is pulley driven, adjust belt to 1/2” of free play at center of the pulleys. Make the first adjustment
after the first 24 hours of operation. Make any additional adjustments when necessary.
Generally, the only maintenance required on the ProVac 3 vacuum pump, is to maintain oil in the oil res-
ervoir. It is imperative that the pump is always getting the proper supply of oil. Periodically or at least
once a week, visually look at the window in the oil dripper, or the wick oiler oil tube, to make sure the
proper amount of oil is being drawn into the pump. If no oil is being sucked into the pump, immediately
turn the pump off. Please refer to the trouble shooting section of this manual for more information on
correcting the problem.
The pump should be isolated from any contaminates so that no foreign substance or moisture can enter
the pump. However, if anything is inadvertently sucked into the pump, the pump should be flushed im-
mediately to remove all contaminates. If it is not immediately flushed, rust can form inside the pump
which can, in turn, cause pump failure.
FLUSHING INSTRUCTIONS
It may be necessary to flush your pump to remove and gum or varnish buildup inside the pump that
causes the vanes to stick inside their slots. This is a simple maintenance operation and should be the
first step when troubleshooting a loss of vacuum in a system. Before starting, be sure the exhaust
from the oil catching devise (oil catch muffler) is directed away from the motor or engine and any
other hot surfaces). Open the flush valve on ProVac 3 model and insert a tube into it. On vacuum
only models, detach the oil tube from its connection to the oil tank. Use kerosene or diesel fuel for
flushing. NEVER USE GASOLINE OR OTHER HIGHLY FLAMMABLE LIQUID FOR FLUSHING.
While the pump is running under vacuum (slide valve in out position on HD models), simply insert the
other end of the tube into the cleaning fluid and allow the pump to draw the fluid in. If there is no vac-
uum present, disconnect the air hose from the top of the slide valve on HD models, or disconnect the
intake hose to the tank on vacuum only models, and pour a couple of ounces of cleaning fluid in. Alter-
nately, let air into the tube in the cleaning solution. It can take up to a quart of cleaning solution to flush
out a pump. When flushing is complete, draw about five ounces of oil into the pump in the same man-
ner. This completes the flushing process. Remove the tube from the flush valve and close it on the HD
models, or reattach the oil tube to the tank oiler on vacuum only models. Finally, reconnect any hoses
that were disconnected.
On badly gummed up pumps it may be necessary to pour a large quantity of cleaning fluid into the pump
(enough to fill the entire pump) and let it sit over night. Be careful to drain as much of the cleaning fluid
as possible out of the pump before attempting to turn the pump on.

STORAGE OF VACUUM PUMPS
Disconnect air lines and pump fittings from the intake and exhaust ports of the air pump. Then open the
flush valve and pour about five ounces of oil into it. Turn the rotor shaft by hand a few times to coat the
inside of the pump housing with oil. Close the flush valve and fill the oil tank with oil. Plug the pump
ports with commercial pipe plugs or the plastic plugs that were supplied with the unit. Coat the shaft
with a small amount of grease or oil to prevent rust buildup during storage. Store the air pump in a cool,
dry place.
IMPORTANT –When RE-STARTING the air pump after storage, turn the pump over by hand to be sure
the shaft and rotor assembly spins freely within the pump housing. If any binding or restriction is felt, the
pump must be taken apart and cleaned.
SLIDE VALVE OPERATION
Page 3
The Conde Slide Valve is a unique changeover valve developed by Conde Pumps to enable the
vacuum pump to be switched from vacuum to pressure mode. This is accomplished by simply
pulling out the slide valve handle (vacuum mode) or pushing in the handle (pressure mode).
The Conde Slide Valve also has a built in check valve to hold tank vacuum even when the pump
is turned off.

CONDE ProVac 3 DISASSEMBLY & ASSEMBLY
TOOLS REQUIRED:
Flathead Screwdriver
1/2” Wrench
9/16” Wrench
Hammer
Rubber Mallet
Fine File
Tool Kit (Optional) Includes: Shaft Collar, Endplate Removal Bolts, Bearing Installation Tool.
Disassembly
1) If pump is HD model, remove the slide valve first by:
a) Detach the oil lines from the pump to the oil reservoir.
b) Remove the four bolts from the top to the slide valve and lift off.
c) Remove gasket under the Slide Valve.
2) Remove the tank oiler (if attached to the pump).
3) Remove all endplate hex screws and all twelve bearing cover screws.
4) Remove both bearing covers, and all shims.
5) Slide the shaft collar (from tool kit) over shaft and tighten screw very securely. Use the fan set
hole to help collar from sliding.
6) Grease the ends of the bolts (from tool kit) and screw them into the three threaded holes located in
the endplate on the opposite side of the pump that the collar is on. Turn the bolts alternating with
no more than one turn at a time until endplate slides off the rotor shaft.

ASSEMBLY
NOTE: Refer to exploded parts diagrams towards end of manual for additional guidance on how parts
are oriented on pump and slide valve. Assemble the pump in a vertical position. This will align the rotor
with the endplates and the housing.
1) De-burr all parts with a fine file, especially where endplate removal bolts were digging into
housing.
2) Determine correct rotor rotation (refer to drawing on previous page). Apply a few drops of oil to
the vanes and check the vane slots for free movement. Set the vanes aside.
3) Start assembly with the end plate that has the dowel pin holes on the right side. (NOTE: the
dowel pins are always on the exhaust side of the pump). This will be the CCW endplate. Press
the oil seal in place.
4) Insert rotor into housing according to rotor rotation. (The pump must be assembled in the same
position as it was disassembled. The rotation can not be changed). Assemble the air pump in
a vertical position. This will align the rotor with the endplates and housing. Position housing
gasket and install the endplate on the housing with the six hex bolts and tighten snugly. Drive
the two dowel pins in place and then tighten hex screws securely.
5) Press bearing on the shaft using a bearing installation tool (from tool kit) or an arbor press.
IMPORTANT: press on the inner race of bearing only. Pressing on the plastic seal may cause
damage to roller bearings.
6) Invert pump assembly and install the vanes in the slots.
7) Press the shaft seal in place on the remaining endplate. Insert dowel pins and place a paper
gasket in position on the housing. Install the endplate with the hex bolts and tighten securely.
8) Press bearing onto shaft as previously done.
9) Shim the pump as follows: First of all, turn rotor by hand to get a “feel” of how it turns when not
binding on the endplates. With rubber mallet, hit one end of the rotor shaft to push rotor
against opposite endplate. Insert shims and bearing cover on the side with the
shaft you hit. Add enough shims so that the cover is flush with the endplate. Screw in bearing
cover screws.
Turn pump by hand, and if rotor feels like it is not binding at all, add more shims until a slight
binding is felt. Once this is done, remove .002” of shims, and then set the remainder aside,
along with the bearing cover. Now, hit the other end of the rotor shaft and repeat process of
adding shims until binding occurs. Remove .002” of these shims and re-install bearing cover
with all screws. Install shims and bearing cover on other side that were previously set aside.
Now turn pump over by hand. IMPORTANT: The pump should spin freely by hand when
completed. If any binding occurs, repeat above process.
10) Reinstall oiler tubes.
11) If pump is a ProVac 3 HD model, reassemble the Slide Valve by:
a) Place gasket(s) on pump housing.
b) Place Slide Valve housing on gasket, making sure that the check valve flapper
assembly is properly seated.
c) Screw in the four mounting bolts on the Slide Valve. Do not over tighten bolts.

PUMP DRIVE CONSIDERATIONS
Conde ProVac 3 pumps can be belt driven or direct driven with couplings from gasoline or diesel en-
gines, electric motors, PTO drives, or hydraulic motors.
BELT DRIVE SYSTEMS
Pulley combinations should be chosen so that pumps run within the specified speed range. The Conde
ProVac 3 is made to operate between 1000 and 1750 rpm. Pulleys should be specified that have ade-
quate “belt wrap” so that maximum contact of belt to pulley can be achieved and minimize the chance of
damage to the pump by over-tightening the belt(s). Please contact Westmoor, Ltd. For information on
proper pulley combinations and belt sizes for your Super model and application. Always leave about
1/2” of belt play when adjusting the belt. Over-tightening the belt can damage the pump and not enough
tension can cause belt slip and loss of pump performance.
DIRECT DRIVE COUPLINGS
We recommend Lovejoy type couplings with a flexible rubber “spider” between the pump mounted
flange and the motor mounted flange. Couplings must be carefully aligned per the manufacturer’s speci-
fications. A small straight edge and set of feeler gauges should be used to insure that the coupling is
aligned properly. Call Westmoor, Ltd. to determine which model coupling is correct for your pump and
application.

INSTALLATION COMPONENTS FOR ProVac 3 PUMPS
Use the diagram as a guide for plumbing your liquid waste tank system. Please contact factory if you
have any questions or need further assistance.
OIL CATCH MUFFLER: An oil catching devise should be part of the pump system. The vacuum pump
exhaust should be connected to the oil catch devise (on slide valve models, connect to the side valve
body opposite the handle). The pressure relief vent should also be plumbed to the oil catch devise since
oil from inside the pump will exhaust out the pressure vent.
VACUUM RELIEF VALVE: A vacuum relief valve is built into the pump manifold on ProVac 3 HD model.
A vacuum relief valve should be installed all other models on the tank.
PRESSURE RELIEF VALVE: As a safety precaution, an additional pressure relief valve should be in-
stalled on the tank for slide valve models. CAUTION: NEVER EXCEED 10 PSI ON NON-CODED
TANKS.
VACUUM GAUGE: A vacuum gauge installed as shown is essential to make sure vacuum levels are cor-
rect. Th gauge is also essential for trouble shooting.
PRIMARY SHUTOFF: A primary shut-off should be installed in the tank to close off the vacuum line to
the pump when the tank is full. The primary trap prevents liquids from entering the pump.
SECONDARY MOISTURE TRAP: The secondary trap spins air to separate moisture out of the air. It will
also shut off the vacuum line in the event that the primary shut-off fails
