Operating Instructions

Vacuum pumps

Pump ranges
These operating instructions concern
the following oil flooded rotary vane
vacuum pumps:
VCAH 100, VCAH 160, VCAH 250
(ultimate vacuum 0.5 mbar abs.)
VCEH 100, VCEH 160, VCEH 250
(ultimate vacuum 10 mbar abs.)
The vacuum capacities at atmosphere
are 100, 160 and 250 m

3

/hr operating

on 50 cycles. The pumping curves
showing capacity against vacuum can
be seen in data sheets D 190 (VCAH)
and D 194 (VCEH).

Description
VCAH and VCEH vacuum pumps are
fitted with a mesh filter on the pump
inlet. On the exhaust side of the pump
an oil mist eliminator is fitted which
has the function of re-circulating oil
back into the circulation system, as
well as providing high efficiency sepa-
ration on the pump exhaust. Situated
between the pump housing and the motor, a high efficiency cooling fan pulls cooling air in through the fan cover. A further
fan inside of the oil cooler (R) results in the cooling of the re-circulating oil. In addition the fan housing and oil cooler
provide protection from accidentally touching either fan when the pump is operating.
A standard built-in non return valve on the inlet of the pump seals the pump from the process when the pump is stopped.
This prevents oil moving into the pumping cylinder when the pump is stationary. Excessive oil in the cylinder could cause
an hydraulic lock when the pump is started and hence undue stress on the rotor blades.
The gas ballast valve (U) which is fitted as standard avoids any condensation of a small amount of water vapour inside
the pump and hence emulsification of the oil. The gas ballast vapour handling capacity can be increased if required to
tolerate higher vapour loads than normal.
All the pumps are driven by a direct flanged three phase, standard TEFV motor via a pin and bush coupling.
Optional extras: The following standard optional extras can be supplied if required: Vacuum regulating valve (ZRV),
additional non return valve (ZRK), dust inlet filter (ZFP), high vacuum suction filter (ZVF), direct on line (DOL) motor
starter (ZMS), star delta starter (ZSG), unloading valve for star/delta starting (ZAE) and various vacuum gauges.

Suitability

The units VCAH and VCEH are suitable for the use in the industrial field i.e. the protection equipments
corresponds to EN DIN 294 table 4, for people aged 14 and above.

These models can be used for the evacuation of a closed system or for a permanent vacuum from:
50 Hz 

 VCAH: 0.5 to 130 mbar (abs.) • VCEH: 10 to 500 mbar (abs.)

60 Hz 

 VCAH: 0.5 to 100 mbar (abs.) • VCEH: 10 to 400 mbar (abs.)

When these pumps are operated permanently outside the ranges listed above, there may be oil seepage at the exhaust
port. If closed systems are evacuated  from atmospheric pressure down to a suction pressure close to the ultimate
vacuum there will be no problem with the oil system, provided the vacuum limit is achieved within a 10 minute pump down
time.

Amounts of water vapour may be handled. Water, other liquids, aggressive or inflammable gases and
vapours may not be handled. For water vapour tolerance, see information I 200.

Handling of inflammable or aggressive gases and vapours is only possible with special versions, if the safety
instructions XE 2 are noted.
When handling oxygen, the saftey instruction sheet XE 3 should be noted.

The ambient and suction temperatures must be between 5 and 40°C. For temperatures outside this range
please contact your supplier.

The standard versions may not be used in hazardous areas. Special versions with Ex-proof motors can be supplied.
The back pressure on the exhaust port must not  0.1 bar.

All applications where an unplanned shut down of the vacuum pump could possibly cause harm to
persons or installations, then the corresponding safety backup system must be installed.
