These data apply for:
Surrounding temperature 30°C.
Continuous operation.
Winter operation with anti-freezing compound
Summer operation without anti-freezing compound
If the anti-freezing compound remains in the
cooling system during summer operation, it is
necessary to increase the volume flow of the
cooling water by ca. 15%. Otherwise the
lower heat dissipation presents the danger of
overheating.
Max
permissible
cooling
water
temperature in the cooling water circuit is
60°C.

Drive
The rotation direction must correspond to the
direction arrow on the machine.
Permitted speed ranges:
Drive by cardan shaft
1200…1500 min
-1
(rpm)
Oth
er drive systems 1000…1500 min
-1
(rpm)
It is essential to take account of the speed
ratio and reduction ratio of the drive (V belt
drive, vehicle auxiliary drive
,…).
We recommend a rotation speed monitoring
device on the machine with a display in the
operating area.
In any case, the rotation speed must be
monitored after the assembly of the rotary
compressor/compressor and vacuum pump,
and an operating notice must be fitted for the
vehicle operator.
Drive by means of combustion engines must
only be used with controlled rotation speed
engines
Axial thrust from the drive must not be
transferred to the rotor shaft.
The drive elements should be fitted to the
rotor shaft with the existing thread M12.
The drive elements must not be hammered
onto the rotor shaft.
4.6.1
Hydromotor drive
For the engine allocation recommended by us, kindly
refer to our measurement sheet M 5689.3.
We will gladly supply you with the correct
mounting flange and a coupling.
The compressor side coupling section is
already mounted by us. After assembly,
the engine side coupling section must not
transfer any axial thrust to the compressor
and vacuum pump.
4.6.2
Drive by flexible coupling
In the case of direct coupling with the drive, e.g. diesel
engine, a flexible revolving coupling must be selected
in accordance with the details supplied by the engine
manufacturer. This coupling must largely compensate
the cyclic irregularity of the drive.
The coupling must be adjusted in exact
adherence to the details supplied by the
manufacturer.
