SAFETY PRECAUTIONS FOR VANE
PUMPS
Please read the following safety information before
operating the 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.
SAFETY

02
Safety
Manual 1865 Rev C p/n 001865 0000
• Do not operate the pump with oxygen-enriched
gas (greater than 23.5% 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 uids and without
proper purges can cause re 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, or
chemical vapor to atmosphere. Check local laws
and ordinances before operating 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 that the pump is completely reassembled,
the guards are properly installed, and all fill and
drain valves are installed and closed before
reconnecting the power supply. Accidental start-
up or operation of the pump while maintenance
is in progress could cause damage or serious
bodily injury.
• Lift the pump only by the lifting lugs supplied
with the pump. Never lift equipment attached to
the 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) may cause surface temperatures as high
as 220°F (104°C).

Manual 1865 Rev C p/n 001865 0000
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 normally the
responsibility of the carrier and should be reported
to them.
The vacuum pump is bolted to the skid. To free the
pump, remove the fasteners.
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 in. (30 – 46 cm) of
access around the pump to allow proper cooling.
Provide adequate ventilation for the fans, radiator,
and motor.
Allow easy access to the oil sight glass for
inspection of the oil level, and allow easy access to
the exhaust port for filter changes. Do not tip over
the pump if it is 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.
Connect the motor according to the electrical
codes through a fused switch in order to protect
the motor against electrical or mechanical overload
conditions. Set the overload of the motor starter 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. Check that these settings are in
line with the voltage at your location. If the voltage
is different, please contact Kinney for motor and
starter information.
Correct direction of rotation is marked by an arrow
on the motor fan housing and is counterclockwise
when looking at the motor from the motor’s fan
side.
OTE:NAfter electrical connections have been
made but before oil has been added,
check the rotation of the motor. If rotation
is backward, reverse any two leads of the
three at the power connection.

Installation
Manual 1865 Rev C p/n 001865 0000
VACUUM CONNECTIONS
Use a pipe size that is at least equal to the size of
the pump inlet connections. Smaller lines result in
a reduced pump capacity and performance.
For pumps operating in parallel on a common main
line, install a manual or automatic operated shut-off
valve or a positive action check valve in the suction
line adjacent to the pump suction flange. Do not
use the built-in anti-suckback valve as a shut-off
valve for the vacuum system.
Remove the plastic protective cap from the inlet
port before connecting the pump to the system.
Should process gas contain dust or other foreign
particles, connect a suitable inline (inlet) filter to the
inlet port. Consult Kinney for recommendations.
Design the vacuum piping so that no liquids such
as condensate or liquid carried over from the
process can reach the pump. If this possibility
exists, install a knock-out liquid separator. Consult
Kinney 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 thread sizes in Table 3-1 are standard on
KVA pumps:
Table 3-1
PUMP MODEL INLET SIZE EXHAUST

KVA400 3 in. NPT 3 in. NPT
KVA630 3 in. NPT 3 in. 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 the recommended
motor oil through the oil fill port. The oil level
should be at the 3/4 mark on the oil sight glass.
Use a non-detergent oil. Oil detergent additives
can clog exhaust filters and shorten their service
life. Kinney recommends KV-100 oil for normal
duty operation or S500 oil for severe duty
operation.
Table 3-2 gives the approximate quantities of oil
required for each model.
Table 3-2

WARNING
!
Do not add or ll oil with pump running or
through the inlet or exhaust ports! Do not
overll.

Manual 1865 Rev C p/n 001865 0000
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 it down. Check
the oil level again and make sure the oil level is
between the 3/4 mark and the FULL mark on the
oil sight glass.
Add oil, if necessary. Add pump oil only 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-
suckback valve will prevent oil in the oil reservoir
from being sucked back into the cylinder after the
pump is shut down. Do not use the anti-suckback
valve as a check valve. Consult Kinney for proper
check valves.
GAS BALLAST
KVA pumps (KVA125TH and larger) 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, which causes
emulsification of the oil that can result i
pump failure.
In applications when the quantity of water vapor is
moderate, Kinney recommends running the pump
for 10 minutes to its normal operating temperature
prior to going on process. Also operate the pump
off process for 10 minutes prior to shutdown. A
slight air bleed (purge) is recommended during
these 10-minute cycles to prevent the vapor from
condensing in the pump.
OPERATION
04

7
Manual 1865 Rev C p/n 001865 0000
KVA Series vacuum pumps require very little
maintenance. To ensure optimum performance,
perform the following maintenance procedures.
INLINE (INLET) FILTER
Check the inline (inlet) filter on a weekly basis.
Clean or replace the filter cartridge when it is dirt .
Consult Kinney for part numbers and replacement
element information.
CAUTION
!
Depending on the mounting position of the lter,
be careful not to allow accumulated foreign
material to fall in the pump suction inlet when
removing the lter cartridge. Horizontal lter
installation is recommended to prevent this.
OIL LEVEL
Under normal circumstances, adding oil between
oil changes should not be necessary. A significant
drop in oil level means there is either an oil leak, a
defective exhaust filter or O-ring, or a leaking anti
suckback valve.
If the pump is smoking excessively, the exhaust
filter may be installed improperl .
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 3/4 mark of the
oil sight glass. Add oil through the oil fill port onl .
CAUTION
!
Do not add oil while the pump is running, since
hot oil can escape from the oil ll port.
OIL TYPE AND QUANTITY
See “Filling the Pump With Oil” on page 5
for details on oil type and quantity.
OIL CHANGE
Oil change frequency depends on the application
and ambient temperature. Kinney recommends
that the customer monitor the condition of the
oil. When using KV-100 oil, Kinney recommends
changing the oil every 500 – 750 operating
hours. When using S500 oil, Kinney recommends
changing the oil every 750 – 1,000 operating
hours.

Maintenance
Manual 1865 Rev C p/n 001865 0000
OIL SPIN-ON FILTER
Replace the spin-on filter at every oil change.
Please consult Kinney’ authorized representative
for part numbers.
EXHAUST FILTER
Replace the exhaust filters every 9 to 18 months
of operation or as necessary. The service life of
the exhaust filters varies depending upon the
application and frequency of oil change. It is
necessary to change the exhaust filters only when
they become clogged. Indications of clogged
exhaust filters are smoke or oil mist coming from
the exhaust of the pump, a higher than normal
motor current, or an exhaust pressure gauge
reading of 3 psig (21 kPa) or greater.
Do not clean or re-use exhaust lters. Dispose
of the exhaust lters properly as they might
contain toxic substances carried over from the
process. Replace the O-rings on the exhaust
lter when changing it.
Please consult a Kinney authorized representative
for part numbers.
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 a Kinney authorized
representative for part numbers.
MAINTENANCE SCHEDULE
The operating life of the pump is greatly affected
by the oil quality and filter condition. Periodic
maintenance will ensure a reliably operating
vacuum pump.
Daily: Visually check oil level and color.
Weekly: Inspect inline (inlet) filte .
Monthly: Check the exhaust filte ’s function.
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.
Every 500 – 2,000 Operating hours: Change the
oil and oil filte . In models equipped with the float
valve with a return line, check the float valve s
operating conditions.
See the motor manufacturer’s manual for the
periodic motor maintenance.
