DESCRIPTION
04
The KVO vane vacuum pumps are single-stage oil
flooded 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 filter 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 flanged, 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-inflammable, non-
aggressive and non-poisonous dry gases
and gas air mixtures
