Description
The V-VCB has a fine micro 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. A fan between the pump housing and the motor provides intensive
air cooling. The fan is located in a fan cover that guards against it being touched.
An integral non-return valve prevents the evacuated system from being ventilated after the pump has stopped.
If the machine has been idle for more than two minutes the connected pipe should be ventilated to atmospheric
pressure.
A gas ballast valve ((U)➝ version (07)) prevents water vapour condensation from getting into the inside of the
pump when it is sucking in small amounts of steam and the pump is at operating temperature.The pump is
driven by a standard flanged single-phase or three-phase motor using a coupling.
4.3
Areas of application
These oil-flooded rotary vane vacuum pumps V-VCB 20 and V-VCB 25 are suitable h for producing vacuums. The suction power with unrestricted suction is 20 and 22.5 m3/h at 50 Hz. Data sheet D 159.
These types are suitable for the evacuation of closed systems or for a continuous vacuum within the following intake pressure ranges:
50 Hz ➝ 2 - 200 mbars (abs.) • 60 Hz➝ 2 - 150 mbars (abs.)
If the machine is operated continuously outside these ranges there is the risk of oil leaking through the outlet
opening. When evacuating closed systems the volume to be evacuated must be no more than 2% of the
nominal pumping capacity of the vacuum pump.
If the unit is switched on more frequently (at regular intervals of about 10 times an hour) or at
higher ambient temperatures and intake temperatures, the excess temperature limit of the motor
winding and the bearings may be exceeded.Please contact the manufacturer should the unit be
used under such conditions.
If it is installed in the open air the unit must be protected from environmental influences, (e.g. by a
protective roof).

Connecting the motor
DANGER
Danger of death if the electrical installation has
not been done professionally.
The electrical installation must only be done by a
qualified electrician observing EN 60204. The operating company has to provide the main switch.
a) The motor‘s electrical data is given on the data
plate (Fig. 2/N) or on the motor data plate (Fig. 2/
P1). The motors comply with DIN EN 60034
and are in protection class IP 55 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, permitted current value).
b. Connect the motor via the motor protection
switch (for safety reasons, a motor protection
switch is required and the connecting cable
must be installed via a cable fitting to provide
strain relief). We recommend using motor protection switches with delayed switch off, depending on possible excess current. Temporary
excess current can occur when the machine is
started cold..
