3.3 Function
The rotary vane pumps of the HenaLine are single-stage, oil-sealed rotary displacement pumps with air
cooling and circulatory lubrication. A non-return valve in the intake flange closes the intake line automatically when switching off the pump and prevents an operating fluid return flow. The integrated oil mist
filter cleans the conveyed gas and prevents the operating fluid mist from being emitted at the exhaust.
The operating fluid collected in the separator is supplied back to the pump. A filter is also installed for
cleaning the operating fluid.
The pump is intended for the evacuation of clean air or other non-aggressive, non-poisonous and nonexplosive gases. Pumping media with a higher density than air results in a higher thermal and mechanical load on the vacuum pump and the drive, and is only permitted after prior consultation with Pfeiffer
Vacuum.
►
You can obtain motor-specific data such as input voltage range from the separately attached motor rating plate.
Air cooling (standard) The vacuum pump is cooled by heat radiation from its surface, the air flow of
the two fan impellers and by the pumped gas.
Oil/water heat exchanger (option) In case of thermally unfavorable ambient conditions, we recommend the use of a pump version with oil/water heat exchanger.
3.3.1 Operating principle
Fig. 3:HenaLine operating principle
The rotary vane pump is an oil-sealed rotary positive displacement pump. The pumping system is made
up of the housing, the eccentrically mounted rotor, and the centrifugally sliding vanes, which divide the
suction chamber into multiple chambers. The volume of each chamber changes periodically as the rotor
rotates. This causes the gas to be continuously drawn in at the vacuum flange and compressed in the
suction chamber by the rotation of the rotor until the exhaust valve opens against the atmospheric pressure and the gas leaves the suction chamber.
Gas ballast
The gas ballast device serves to add a limited amount of mixture of ambient air or inert gas to the process gas in order to counteract the condensation from vapor contents. By increasing the air content in
the suction chamber, the opening pressure of the exhaust valve has already been reached before condensation forms in the expelled gas/vapor mixture. In doing so, the pump-specific limits of the water va-
13/58
Product description
por tolerance must be observed. The ultimate pressure achieved with the gas ballast is higher than operation without gas ballast.
Operating fluid
The vacuum pump oil, also referred to as operating fluid, fulfills several functions in a rotary vane pump:
in addition to the lubrication of all moving parts, the operating fluid fills a part of the dead volume below
the exhaust valve, and seals the gap. In addition, the operating fluid supports cooling and, under the
aspect of corrosion protection and resistance, may also have to be selected for process suitability. From
the operating fluid reservoir, dosed operating fluid is supplied to the pump system and mixed with the
conveyed gas. In the downstream operating fluid separator, the operating fluid is separated from the exhaust air flow and thus retained in the rotary vane pump.
3.3.2 Operating fluid return via the float valve
The vacuum pumps are equipped with an operating fluid return as standard. If the operating fluid collected in the operating fluid separator reaches a certain level, a float valve opens and the ejected operating fluid is returned to the intake port of the vacuum pump.
Function of the operating fluid return
The operating fluid return functions only at an operating pressure of < 800 hPa.

6.1 Commissioning
Before switching on
1.
Check the operating fluid in the sight glass.
2.
Compare the voltage and frequency specifications on the motor rating plate with the available
mains voltage and frequency.
3.
Take appropriate steps (e.g. dust filter) to adequately protect the vacuum pump against taking in
contamination.
4.
Check the operating fluid regularly or change it more frequently.
5.
Check the exhaust connection for free passage (max. permissible pressure: atmospheric pressure).
6.
Actuate the shut-off units so that the shut-off units open before or at the same time as the pump
starts up.
6.2 Switching on
You can switch on the vacuum pump in every pressure range, between atmospheric pressure and ultimate pressure. The optimal operating condition of the vacuum pump is achieved in continuous operation. Cyclical operation is possible, however do not exceed 10 cycles per hour. The operating phase
should always be longer than the downtime.
When pumping down dry gases, no special precautions are required. In order to achieve the lowest
possible ultimate pressures, the gas ballast valve should be closed.
WARNING
Risk of burns from ejected hot oil mist
During operation, hot pressurized oil mist escapes from the operating fluid separator.
►
Only operate the vacuum pump with the operating fluid filler screw securely fitted.
►
Open the locking screws on the separator only while the vacuum pump is switched off.
CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C.
►
Provide suitable touch protection.
NOTICE
Risk of damage to the drive from increased motor current consumption
At an intake pressure of approximately 300 hPa and under unfavorable operating conditions (such as
for example exhaust side counterpressure), the power input exceeds the rated current.
►
Limit the maximum power input of 1.5 times the rated current to max. 2 minutes (in accordance
with EN 60034-1).
Switching on the vacuum pump
1.
Switch the vacuum pump on at the mains switch.
2.
Close the vacuum flange and gas ballast valve.
3.
Allow the vacuum pump to warm up prior to process start, with the vacuum flange closed, for approximately 30 minutes.
4.
Check the operating fluid level with the vacuum pump running and at operating temperature.
–
The fill level must be within the marks on the sight glass during operation.
–
Check the operating fluid fill level daily during continuous operation, and every time the pump
is switched on.
–
The fluid can be refilled during operation in the final vacuum.

NOTICE
Risk of damage from condensation in vacuum pump
During operation without gas ballast, condensation may form as a result of the vapor compatibility of
the vacuum pump being exceeded.
►
Pump condensable vapors only when the vacuum pump is warm and the gas ballast valve open.
►
Allow the vacuum pump to run on after process end for another 30 minutes with the gas ballast
valve open.
–
This cleans the operating fluid and protects the vacuum pump against corrosion.
Behavior of process gases with condensable vapors
►
Operate the vacuum pump with gas ballast, i.e. with the gas ballast valve open.
6.3.1 Gas ballast valve – standard version
To avoid condensation of condensable vapors in the pump when pumping them down, air is fed into the
working chamber periodically via the gas ballast valve at the start of the compression phase.
The gas ballast valve is closed when turned to the right to position "0" and open when turned to the left
to position "I". Intermediate settings are not possible.
