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 filter 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 sufficiently 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 flanged 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-inflammable, non-
aggressive, and non-poisonous dry gases
and gas air mixtures.
UNACCEPTABLE OPERATING MODES
• Extracting, conveying, and compressing
explosive, inflammable, 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.
• Installing in environments that are at risk of
explosions.
• Using the machine in areas with ionizing
radiation.
•
