DESCRIPTION
04
The KVC Series model range has a connecting
thread on the suction side and an exhaust silencer
on the pressure side. With the KVC Series the
incoming air is cleaned by a lter cartridge.
The KVC Series is a double-shaft rotary claw
vacuum pump which the claws roll off against each
other contact free and dry. The counter-rotating
claw rotors are synchronized by a gear pair in the
gearbox. The synchronous gears and the bearings
on the motor side are lubricated with oil. These
components are in a gearbox that also contains
the oil supply. Oil slingers always ensure that the
bearings and the gears are sufciently supplied
with oil at all permissible speeds.
The pumping chamber has no sealants or
lubricants. The gearbox and the compression
chamber are separated from each other by
special seals. The gearbox is sealed from
the outside with shaft seals and o-rings, and
the compressor chamber with piston rings.
Between the piston ring and lip seals there is an
atmospherically ventilated area that can be loaded
with sealing gas (special version).
The KVC Series is driven by an IEC (KVC60 only)
and NEMA anged three phase motors via a
coupling (with an elastomer component). A vacuum
regulating valve is used to set the vacuum to the
required values. This regulating valve is pre-set
at the factory and should not be adjusted without
consulting the factory.
DESIGNATED USE
The machine must only be operated in such areas
as are described in the operating instructions:
• Only operate the machine in a 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 suction temperature of
between 40 and 104°F (40°C). Please contact
MD-Kinney for temperatures outside this range.
• The machine may convey, compress, or extract
the following media:
○ All non-explosive, non-inammable, non-
aggressive, and non-poisonous dry gases
and gas air mixtures.
UNACCEPTABLE OPERATING MODES
• Extracting, conveying, and compressing
explosive, inammable, aggressive or poisonous
media, solvents as well as gaseous oxygen and
other oxidants, water vapor, liquids, or
solid materials.
• Using the machine in non-commercial plants
if the necessary precautions and protective
measures have not been taken in the plant.

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
!
Vacuum pump housing and
associated piping or accessories
may become hot enough to cause
major skin burns on contact as a
result of process conditions.
WARNING
!
Use lockout / tagout procedures to disable the
electrical energy source before any service or
work is done on the vacuum pumps.
CAUTION
!
Avoid extended exposure in
close proximity to machinery with
high intensity noise levels. Wear
adequate ear protection.
CAUTION
!
Other potential hazards to safety may also be
associated with operation of this equipment. All
personnel working in or passing through the
area should be warned by signs and trained to
exercise adequate general safety precautions.
Use proper care and good procedures in
handling, lifting, installing, operating, and
maintaining the equipment.

Installation
Manual 1866 Rev A p/n 1866
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.
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.

14
05
Installation
Manual 1866 Rev A p/n 1866
Length of the Connection Pipes
With connection pipes that have the same pipe
cross section as the machine connection and area
more than 3m long, a non-return valve must be
installed in order to avoid reverse operation when
the machine has stopped.
Exhaust Air Must Not be Restricted
Do not block the exhaust pipe of the pump
(maximum discharge pressure is 22.5 Torr or 30
mbars). When the exhaust air pipe is connected it
must be checked regularly for impurities.
Material damage resulting from the forces and
torques of the pipes on the unit being too high.
Only screw pipes in by hand.
Do not operate without the standard
regulating and relief valve. If the permissible
vacuum is exceeded (see data plate) the
machine may be damaged.
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

OPERATION
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 counter-
clockwise.

ENSURING OPERATIONAL SAFETY
DANGER
!
Danger of death from touching
live parts. Before maintenance
work disconnect the machine
by pressing the main switch or
unplugging it and ensure it cannot
be turned on again.
WARNING
!
Hot surfaces and equipment.
During maintenance work there
is the danger of getting burnt on
hot components and by machine
lubricating oil. Allow ample time
for the machine to cool down prior
to maintenance work.
Regular maintenance work must be carried
out in order to ensure operational safety.
Maintenance intervals also depend on the
operational demands on the machine. Observe
the safety instructions described in the section
labeled “Safety” on page 12. The entire unit
should always be kept in a clean condition.
