REFER TO MANUAL SAFETY INSTRUCTIONS.
CAUTION
SAFETY PRECAUTIONS FOR VANE PUMPS
Please read the following safety information on this page before operating your vacuum pump.
• Do not operate the pump without the guards properly attached. Disconnect the pump motor from the electrical supply at the
main disconnect before removing the guards. Replace the belt guard before reconnecting the power supply to the pump motor.
Operating the pump without the belt guard properly installed exposes personnel in the vicinity of the pump to risk from rotating
drive components.
• Do not operate the pump with oxygen-enriched gas (greater than 21% by volume) in the suction line, unless the pump has
been prepared with an inert fluid suitable for the application and equipped with seal and start/stop purge system.
WARNING: Pumping oxygen-enriched gases with mineral oil or other non-inert fluids and without proper
purges can cause fire or explosion in the pump, resulting in damage or serious bodily injury.
• Take precautions to avoid prolonged or excessive exposure to oil mist or process materials emanating from the discharge of
the pump.
• Do not allow the pump to discharge into a closed, or inadequately ventilated room. Where process vapor contains environmentally
unfriendly chemical vapor, pump discharge must be connected to the properly sized scrubber system to neutralize the harmful
chemicals prior to the discharge to the atmosphere. Laws and ordinances may pertain to your local area regarding discharge of
oil mist, oil vapor, chemical vapor to atmosphere. Check local laws and ordinances prior to operation of the pump with discharge
to outside atmosphere.
• Do not restrict the pump discharge in any way, or place valves in the discharge line. The vacuum pump is a compressor and will
generate high pressures without stalling the motor when operated at low suction pressures. Excessive pressure could cause
damage or serious bodily injury.
• Disconnect the pump motor from the electrical supply at the main disconnect before disassembling or servicing the pump. Make
sure pump is completely reassembled, the guards are properly installed, and that all fill and drain valves are installed and closed
before reconnecting the power supply. Accidental starting or operation of the pump while maintenance is in progress could cause
damage or serious bodily injury.
• Lift pump only by the lifting lugs supplied with the pump. DO NOT lift equipment attached to pump by the pump lifting lugs.
• Do not touch hot surfaces on the pump. In normal operation at low pressures, surface temperatures will not normally exceed
180° F (82° C). Prolonged operation at 200 Torr (267 mbar a) may cause surface temperatures as high as 220° F (104° C)

INTRODUCTION
CONGRATULATIONS on your purchase of a new KINNEY®KVA or KVAH oil lubricated, rotary vane vacuum pump from Tuthill
Vacuum & Blower Systems. Please examine the pump for shipping damage, and if any damage is found, report it immediately to the
carrier. If the pump is to be installed at a later date, make sure it is stored in a clean, dry location and rotated regularly. Make sure
covers are kept on all openings. If pump is stored outdoors be sure to protect it from weather and corrosion.
KINNEY KVA/KVAH vacuum pumps are built to exacting standards and if properly installed and maintained will provide many years
of reliable service. We urge you to take time to read and follow every step of these instructions when installing and maintaining your
pump. We have tried to make these instructions as straightforward as possible. We realize that getting any new piece of equipment
up and running in as little time as possible is imperative to production.
This manual is written to cover KVA and KVAH Model vacuum pumps. Please identify the model number and serial number when
ordering parts.
WARNING: Serious injury can result from operating or repairing this machine without first reading the service
manual and taking adequate safety precautions.
IMPORTANT: Record the model and serial numbers of your pump in the OPERATING DATA form on the inside back cover
of this manual. You will save time and expense by including this reference identification on any replacement part orders,
or if you require service or application assistance.
INSTALLATION
UNPACKING
Inspect the box and pump carefully for any signs of damage incurred in transit. Since all pumps are ordinarily shipped F.O.B. from our
factory or regional warehouse, such damage is the normal responsibility of the carrier and should be reported to them.
The vacuum pump is bolted to the skid, and the fasteners must be removed to free the pump.
The inlet and exhaust of the pump are covered with plastic caps to prevent dirt and other foreign substances from entering the pump.
Leave these caps in place until you are ready to pipe the pump to your equipment.
LOCATION
Install the pump in a horizontal position on a level surface so that the pump is evenly supported on its rubber feet. Leave 12-18” of
access around the pump to allow proper cooling. Adequate ventilation must be provided for the fans, radiator, and motor.
Allow access to the oil sight glass in order to inspect the oil level, and the exhaust port for easy access to change the exhaust filters.
Do not tip the pump over if filled with oil.
POWER REQUIREMENTS
A schematic diagram for the electrical motor terminal connections is located in the junction box of the motor or on the motor
nameplate.
The motor must be connected according to the electrical codes through a fused switch in order to protect the motor against electrical
or mechanical overload conditions. The overload of the motor starter must be set at a level equal to the full load motor current listed
on the motor nameplate.
If the pump is supplied with a motor starter, it is preset at the factory according to customer specifications. It is advisable to check that
these settings are in line with the voltage at your location. If the voltage is different, please contact Tuthill Vacuum & Blower Systems
for motor and starter information.
Correct direction of rotation is marked by an arrow on the motor fan housing and is counter clockwise when looking at the motor from
the motor’s fan side.
NOTE: After electrical connections have been made, but prior to filling with oil, the rotation of the motor should be checked.
If backward, reverse any two leads of the three at the power connection.

5
VACUUM CONNECTIONS
Use a pipe size that is at least the size of the pump inlet connections. Smaller lines result in a reduced pump capacity and
performance.
Pumps operating in parallel on a common main line should have a manual or automatic operated shut-off valve or positive action
check valve, installed in the suction line adjacent to the pump suction flange. The built-in anti-suck back valve should not be used as
a shut-off valve for the vacuum system.
Remove the plastic protective cap from the inlet port prior to connection of the pump to the system.
Should process gas contain dust or other foreign particles, a suitable in line (inlet) filter should be connected to the inlet port. Consult
Tuthill Vacuum & Blower Systems for recommendations.
The vacuum piping should be designed to ensure that no liquids such as condensate or liquid carried over from the process can
reach the pump. If this possibility exists, a knock-out liquid separator should be installed. Consult Tuthill Vacuum & Blower Systems
for recommendations.
If an exhaust manifold is connected, install a drip leg and drain near the pump exhaust to prevent exhaust condensation from entering
the exhaust box. The following thread sizes are standard on KVA/KVAH pumps:
PUMP MODEL INLET SIZE EXHAUST SIZE
KVA12 / KVA21 1/2” NPT Open Grid
KVA25 / KVAH25
KVA40 / KVAH40 1 1/4” NPT 1 1/4” NPT
KVA63 / KVAH63

KVA250D / KVAH250D 2” NPT 2” NPT
KVA400C 3” NPT 3” NPT
KVA630C 3” NPT 3” NPT
FILLING THE PUMP WITH OIL
The pump is shipped without oil. After level installation and correct rotation has been established, fill the pump with recommended
motor oil through the oil fill port. Oil level should be at the 3/4 position on the oil sight glass.
A non-detergent oil should be used. Tuthill Vacuum & Blower Systems recommends the use of KV-100 oil for normal duty operation
or S500 oil for severe duty operation.
Oil detergent additives can cause exhaust filters to become clogged and shorten their service life.
The following table gives the approximate quantities of oil required for each model.
PUMP MODEL CAPACITY (QUARTS)
KVA12 / KVA21 0.5
KVA25 / KVAH25
KVA40 / KVAH40 1.0

OPERATION
START-UP
Check rotation of the motor as described in “Power Requirements” on page 4. Fill the pump with oil as described in “Filling the Pump
with Oil” on page 5.
Start the pump with the inlet closed. Run the pump for a few minutes and then shut down. Check the oil level again and make sure
the oil level is between the ¾ mark and full on the upper oil sight glass.
Add oil, if necessary. Pump oil should only be added when the pump is off and circulating oil has sufficient time to return to the oil
sump.
STOPPING THE PUMP
To stop the pump, turn off the power. A built in anti-suck back valve will prevent oil from the oil reservoir being sucked back into
the cylinder after the pump is shutdown. Do not utilize the anti-suck back valve as a check valve. Consult Tuthill Vacuum & Blower
Systems for proper check valves.
GAS BALLAST
KVA and KVAH pumps are equipped with a gas ballast. The gas ballast valve is located between the inlet port and the exhaust box.
Its main function is to prevent water vapor from condensing in the pump that causes emulsification of the oil resulting in possible
pump failure.
In applications, when the quantity of water vapor is moderate, it is recommended to run the pump for 10 minutes to its normal
operating temperature, prior to going on process. The pump should also be operated off process for 10 minutes prior to shut down. A
slight air bleed (purge) is recommended during these 10-minute cycles to prevent the vapor from condensing in the pump.
MAINTENANCE
KVA Series vacuum pumps require very little maintenance. To ensure optimum performance, the following maintenance steps should
be followed.
INLINE (INLET) FILTER
Check inline (inlet) filter on a weekly basis. The filter cartridge should be cleaned or replaced when dirty. Consult Tuthill Vacuum &
Blower Systems for replacement element information.
CAUTION: Depending on the mounting position of the filter, be careful not to allow accumulated foreign material
to fall in the pump suction inlet when removing the filter cartridge. Horizontal filter installation is recommended
to prevent this.
EXHAUST FILTER
Replace the exhaust filters every 9 to 18 months of operation or as necessary. The service life of these filters varies depending upon
the application, and frequency of oil change. It is necessary to change these filters only when they become clogged. Indications
of clogged filters are smoke or oil mist coming from the exhaust of the pump, higher than normal motor current, and the exhaust
pressure gauge reading of 3 psig or greater.
Do not clean or re-use these filters. Filters must be disposed of in a proper way as they might contain toxic substances carried over
from the process. Replace O-rings on filter when changing.
MAINTENANCE SCHEDULE
See the motor manufacturer’s manual for the periodic motor maintenance.
DAILY: visually check oil level and color.
WEEKLY: inspect inline (inlet) filter.
EVERY 2-6 MONTHS: drain and discard oil from pump while hot. Refill with fresh oil.
EVERY 9-18 MONTHS: replace exhaust filter elements and O-ring.
The operating life of the pump is greatly enhanced based on the oil quality and condition of the filters. Periodic maintenance will
ensure a reliable operating vacuum pump.

OVERHAUL KIT AND ACCESSORIES
An overhaul kit contains a set of gaskets, o-rings, vanes, bearing, bearing sleeves, shaft seals, and taper pins. Please consult Tuthill
Vacuum & Blower Systems’ Service Department for information.
OIL LEVEL
Under normal circumstances it should not be necessary to add oil between oil changes. A significant drop in oil level means there is
either an oil leak, a defective exhaust filter or O-ring, or a leaking anti-suck back valve.
If the pump is smoking excessively, the exhaust filter may be installed improperly.
It is normal for the oil to be foamy or lightly colored in an operating pump. This may be normal aeration of the oil. If the oil appears
milky or dark colored, it is contaminated or burned and must be changed.
Check the oil level only when the pump is shut off. Replenish oil if it drops below the ¼ mark of the top sight glass. Oil must be added
through the oil fill port only.
CAUTION: Do not add oil while the pump is running, since hot oil can escape from the oil fill port.
OIL TYPE AND QUANTITY
See “Filling the Pump with Oil” section on page 5 for details on oil type and quantity.
OIL CHANGE
When using KV-100 oil, it is recommended to change the oil every 500-750 operating hours. When using S500 oil, it is recommended
to change the oil ever 750-1000 operating hours.
Oil change frequency is dependent upon the application and ambient temperature. It is recommended that the customer monitor the
condition of the oil.
OIL SPIN-ON FILTER
Replace spin on filter at every oil change.
