Set up and operation
4.2 Description
The C-VLR model range has a connecting thread on the suction side and an exhaust silencer on the pressure side. With the C-VLR 60 the incoming air is cleaned by a fi lter cartridge. The C-VLR 100-500 have a
micro fi lter on the suction side.
The ZEPHYR C-VLR is a double shaft rotary piston vacuum pump in which the claws roll off against each
other contact free and dry. The counter-rotating claw rotors are synchronised by a gear pair in the gearbox.
The synchronous gearbox gear wheels and the bearing on the motor side are lubricated with oil. These
components are in a gearbox that also contains the oil supply. Oil conveying devices always ensure that the
bearings and the gear wheels are suffi ciently supplied with oil at all permissible speeds. The feed chamber
has no sealants or lubricants. The C-VLR 400 and 500 sizes have grease lubricated bearings on the B side.
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, the compressor chamber with piston rings. Between
the two there is also another atmospherically ventilated area that can be loaded with sealing gas (special
version).
The C-VLR 100-500 is enclosed in an insulation hood.
In order to dissipate compression heat, the cooling air is sucked through between the machine and the hood
using drum fan that sucks in the fresh cooling air (Fig. 3/E) and discharges the heated air out of the cooling
air outlet (Fig. 3/F). The ZEPHYR VLR is driven by standard fl anged three phase motors via a coupling (with
an elastomer component).
A vacuum regulating valve (Fig. 2/C) is used to set the vacuum to the required values.
4.3 Areas of application
These contact free running claw vacuum pumps C-VLR can be operated constantly at any pressure between
atmospheric and an inlet pressure of:
100 mbar (abs.) ➝ C-VLR 60 / 150
150 mbar (abs.) ➝ C-VLR 100 / 120
200 mbar (abs.) ➝ C-VLR 250 / 251 / 300
250 mbar (abs.) ➝ C-VLR 400 / 500
The pumping capacity with unrestricted suction is 60, 100, 120, 150, 211, 235, 300, 385 and 500 m
3
/h at
50 Hz. Data sheet D 880 shows the dependency of the pumping capacity on the intake pressure.
If the unit is switched on more frequently (at regular
intervals of about 12 times an hour (C-VLR 60 - 150)
or 10 times an hour (C-VLR 250 - 500)) 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.

Installation
5.3 Connecting pipes
a) Vacuum connection at (Fig. 2/A... 4/A).
NOTICE
Material damage resulting from the forces and
torques of the pipes on the unit being too high.
Only screw pipes in by hand.
The pumping capacity of the vacuum pump
is reduced if the suction pipe is too narrow
and/or too long..
b) The discharged air can be blown out through
the exhaust silencer (ZSZ) at (Fig. 2/B... 4/B) or
conducted away using a hose or a pipe.
NOTICE
Length of the connection pipes
With connection pipes that have the same pipe
cross section as the machine connection and are
more than 3m long, a non-return valve especially
for the purpose must be installed in order to avoid
reverse operation when the machine has stopped.
Exhaust air must not be restricted
No blocking systems must be built into the
exhaust air pipe (max. pressure difference 30
mbars). When the exhaust air pipe is connected it
must be checked regularly for impurities.

5.6 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
qualifi ed 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. 3/N) or on the motor data plate (Fig. 3/
). The motors comply with DIN EN 60034
P
1
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 plug connection or
the motor protection switch (for safety reasons,
a motor protection switch is required and the
connecting cable must be installed via a cable
fi tting to provide strain relief).
We recommend using motor protection switches
with delayed switch off, depending on possible
excess current. Temporary excess current may
occur when the machine is started cold.
