2.1. Main Features
2. Understanding The Pumping Station
Proper Use
– The Roots vacuum pumping station may only be used for
the purpose of generating vacuum.
– Do not pump corrosive or explosive gases (a special
version for these applications is available on request).
– Do not operate the pumping station in areas where there is
a danger of explosion. For this a special ex version is
required.
– Accessories other than those referred to in these
operating instructions may not be used without the
agreement of Pfeiffer Vacuum.
Improper use will cause all liability claims and guarantee
rights to be forfeited.
The WOD series comprises a combination of Roots and rotary
vane vacuum pumps with oil mist filter. A high vacuum safety
valve* with ventilation valve which is integrated in the rotary
vane vacuum pump is arranged between the Roots vacuum
pump and the rotary vane vacuum pump. This shuts off the
vacuum chamber in the event of a power failure and
ventilates the backing pump.
The technical details concerning the components used in the
pumping station are contained in the relevant operating
instructions.
The pumping station is fitted in a frame and is equipped with
all the necessary connection lines and including counter
flanges on the intake and the pressure sides. The pumping
station is designed to pump dry, inert and non-reactive gases
and gaseous mixtures.
The maximum working range is from atmospheric pressure to
approx.:
1 z10-3 mbar with 1 stage rotary vane vacuum pump.
< 3 z10-4 mbar with 2 stage rotary vane vacuum pump.

3.1. Pumping Station Set-Up And Location
– The pumping station is mounted in a base frame, ready for
connection.
– If parts of the system have to be detached for
transportation reasons, they should be re-fitted in
accordance with the assembly plan.
– The set-up location should be so selected that the ambient
temperature is in the range +12 ...+ 40 °C and adequate air
circulation must be provided.
– The pumping station must be protected from draughts and
the direct effect of the weather.
– If the pumping station is intended for stationary operations,
it should be aligned horizontally to the standing surface
and anchored. Borings are provided in the base frame for
securing to the standing surface.
– Before setting up the pumping station, the loading capacity
of the standing surface must be checked against the
weight of the pumping station.
– Where mobile versions of the pumping station are involved
it must be ensured that during operation the pumping
station is placed on a horizontal surface and that the
rollers are locked.
3.2. Connecting The Vacuum Side
➡The connection between the vacuum chamber and the
pumping station should be as short as possible.
➡Ensure there are no welding beads, scaling, loose parts
and the similar which could get into the intake line of the
Roots vacuum pump.
➡Connect the piping free of stress.
➡To compensate for any stress it is recommended to fit a
bellows into the piping.
3.3. Connecting The Exhaust Side
Lay exhaust lines without shut-off units. If shut-
off units are fitted there is a danger that over-
pressure can build up in the lines. The local
regulations concerning accident prevention
must be followed (see the operating
instructions for the pumps).
Exhausted gases and vapours can, depending
on the application, be hazardous to health
and/or environmentally harmful. When working
with toxic substances the relevant regulations
must be followed.
WARNING
CAUTION
3.4. Electrical Connection
The electrical connection must be carried out in
accordance with local regulations.
– The voltage and frequency values on the rating plate of the
pumping station, the Roots vacuum pump and the rotary
vane vacuum pump must concur with the mains voltage.
– The pumping stations with switch cabinet are internally
completely wired. The electrical connections must be
carried out in accordance with the valid circuit diagram
(see enclosure). This also applies for other voltages.
– The drive motors of the Roots vacuum pump and the rotary
vane vacuum pump are switched so that they rotate in the
same direction.
Safety Feature
– In the switch cabinet version the phase sequence relay
has a simultaneous monitoring function for the rotary vane
pump blow-out fuse (pump 2).
– The mains unit for vacuum measurement has an internal
micro fuse (100 mA).
CAUTION

3.5. Filling In Operating Fluid
The pumping station has been tested using
operating fluid P3.
Only by using this operating fluid are
guarantees relating to attainment of final
pressures and trouble free functioning applica-
ble. The pumping station delivery consignment
contains a filling of operating fluid (only for P3).
Used operating and lubricating agents must be
disposed off in accordance with the local
regulations.
Pumps for special applications (e.g. for pumping corrosive
gases) can be operated with special operating fluids such as
F5, T 100 and other Pfeiffer Vacuum operating fluids. The use
of such operating fluids requires prior agreement with Pfeiffer
Vacuum.
➡Fill operating fluid in accordance with the operating
instructions for the pump concerned.
– Amount and type of operating fluid please see always
rating plate.
➡Check the sealing oil level (lubricant) in the oiler of the
WKP-Pumps. If necessary fill up the oiler to a maximium of
half-filled when the pump is cold.
CAUTION
3.6. Noise Reduction
Under certain operating conditions it is possible that the
pumping station noise level can exceed the legally prescribed
limits. In these cases the operator will have to take protective
action. Noise protection hoods are available from Pfeiffer
Vacuum.
If ‘’F5’’ is heated above 300°C, toxic vapours
which can harm the airways are given off.
Do not allow ‘’F5’’ to come into contact with
tobacco products (danger of poisoning when
ignited). The precautions necessary in the
handling of chemicals must be observed.
