DESCRIPTION
04
The KVO vane vacuum pumps are single-stage oil
ooded rotary vane vacuum pumps. The rotary vane
divides the pump housing into several chambers
whose volumes change periodically. The oil ensures
for the sealing of the gap, an optimum lubrication
and the dissipation of the compression heat.
The pumps have an integrated mesh lter on the
suction side and on the outlet side an oil and oil
mist separator to return the oil to the oil circulation
system. With optimum air routing, a fan and an oil
cooler ensure for the cooling of the oil and pump
housing. An integrated non-return valve prevents
the evacuated system from being ventilated after the
pump has stopped. With standstill times longer than
two minutes, we recommend venting the connecting
lines to atmospheric pressure in order to avoid
possible damage.
When the pump is at operating temperature,
a standard gas ballast valve prevents the
condensation of low quantities of water vapor inside
the pump. The water vapor compatibility may vary
depending on the pump version.
It is driven via a coupling by a anged, three-phase
standard motor.
DESIGNATED USE
The machine must only be operated in such areas
as are described in the operating instructions:
• Only operate in technically perfect condition
• Do not operate the machine when it is only
partially assembled
• The machine must only be operated at an
ambient temperature and a suction temperature
of between 5 and 40°C Please contact us for
temperatures outside this range.
• The machine may convey, compress or extract
the following media:
○Air - The air extracted may contain water
vapor but no water or other liquids. For
water vapor compatibility.
○All non-explosive, non-inammable, non-
aggressive and non-poisonous dry gases
and gas air mixtures

SAFETY
DANGER
!
Internal and external rotating
parts of the pump and driving
equipment can produce serious
physical injuries. The pump
should never be run with the inlet
or discharge piping removed. If
it becomes necessary to inspect
the rotating parts of the pump or
to change the belt, be absolutely
sure that all power to the motor
controls has been shut off, the
motor controls are locked out,
and properly tagged before
proceeding.
WARNING

Installation
Manual 1867 Rev A p/n 1867
WARNING
!
Never attempt to change or add lubrication while
the pump is running. Failure to heed this warning
could result in damage to the equipment or
personal injury.
WARNING
!
Properly dispose of spent lubricants. Refer to the
manufacturer of the lubricant and any applicable
regulations to ensure proper and safe disposal.
If the oil level is too low, bearings and seals will
be damaged as a result of improper lubrication.
The machine may only be operated when it is
set up horizontally.
Material damage resulting from the machine
tipping over and falling.
When installed at more than 3280 feet (1000
meters) above sea level a reduction in power
is noticeable. In this case we would ask you to
contact Kinney directly for guidance.
FILLING THE PUMP WITH OIL
Use oil recommended by Kinney and see the
specications for the quantity of oil required to ll
the pump. Remove the oil ll plug at the top of the
housing and add oil until the level reaches mid-
center of the gauge. With the pump shut off, add or
drain oil as necessary to keep the oil level.
CAUTION
!
Do not overll the pump as excess oil will be
blown out the discharge during the high pressure
operation of the pump.
LOCATION
The pump should be mounted on a at, level
surface. There should be enough space around
the pump to allow for safe maintenance work and
periodic inspections. This includes, at a minimum,
the ability to access oil ll and drain locations,
view the oil level glass and the oil temperature and
pressure gauges. Allow accessibility to all sides.
Do not close cooling air entry and exit.
Foundation
The foundation for the pump assembly should be
at and level, and have adequate load-bearing
capacity. The pump and its base frame, peripheral
equipment and piping should be installed after the
foundation concrete has been cured. It is possible
to install the machine on a rm base without
anchoring. When installing on a sub-structure
Kinney recommends xing with exible buffers.
PIPING CONNECTIONS
WARNING
!
Pipe loading on the pump should be negligible
as pipe loading can cause distortion of the pump.
Use proper supports and pipe hangers to assure
that there is no loading.
VACUUM CONNECTION
The pumping capacity of the vacuum pump is
reduced if the suction pipe is too narrow and/or long.
Discharged air can be blow out through the exhaust
silencer conducted away using a hose or a pipe.

13
05
Installation
Manual 1867 Rev A p/n 1867
Exhaust Air Must Not be Restricted
When the exhaust air pipe is connected it must be
checked regularly for impurities.
WARNING
!
Do not block the exhaust pipe of the pump.
Material damage resulting from the forces and
torques of the pipes on the unit being too high.
Only screw pipes in by hand.
CONNECTING THE MOTOR
DANGER
!
Danger of death if the electrical
installation is not professionally
completed. The electrical
installation must be completed by
a qualied electrician observing
EN 60204. The operating
company is required to provide
the main switch.
The motor’s electrical data is given on the data
plate or on the motor data plate. The motors
comply with DIN EN 60034 and are in protection
class IP55 and insulation class F. The appropriate
connection diagram is located in the motor’s
terminal box (not for the plug connection version).
The motor data must be compared with the data of
the existing mains network (current type, voltage,
network frequency, and permitted current value).
Connect the motor via the plug connection or
the motor overload. For safety reasons, a motor
overload is required and the connecting cable
must be installed via a cable tting to provide
strain relief. Kinney recommends using motor
protection switches with delayed switch off,
depending on possible excess current. Temporary
excess current may occur when the machine is
started cold.
Power Supply
The conditions at the installation location must
match the information on the motor data plate.
Without derating the following is permissible:
• ± 5% Voltage deviation
• ± 2% Frequency deviation

14
OPERATION
06
Manual 1867 Rev A p/n 1867
WARNING
!
Improper use may lead to severe or fatal injuries.
Therefore be sure to obey the safety instructions.
CAUTION
!
Hot surfaces. When the machine
is at operating temperature the
surface temperature on the
components may go above 158°F
(70°C).You must avoid touching
the hot surfaces. These areas are
marked with warning plates.
CAUTION
!
Noise emission. The highest
noise pressure levels measured
as per EN ISO 3744. When
spending a long time in the vicinity
of the running machine use ear
protection to avoid permanent
damage to your hearing.
Wait until the machine stops. The machine
must only be switched on again after it stops.
CHECKING ROTOR
ROTATION DIRECTION
Operating in the wrong direction of rotation leads
to damage to the machine. Use a phase sequence
indicator to check the direction of rotation
(clockwise rotating eld).
The intended direction of rotation of the drive
shaft is shown by the rotary direction arrow on the
motor ange. Start the motor briey (maximum of
2 seconds) to check the direction of rotation. When
looking at the motor fan, it must rotate clockwise.
Operating in the wrong direction of rotation
leads to damage to the machine. Use a phase
sequence indicator to check the direction of
rotation (anti-clockwise rotating eld).
After correcting the direction of rotation if
necessary, start the motor again and stop it again
after 2 minutes in order to top missing oil up to the
upper edge of the sight glass. This topping up at
the lling point must be repeated until all the oil
pipes have been lled completely. The lling point
must not be open when the pump is running.
