3.5. Connecting The Vacuum Side
As standard, the pump is equipped with an inlet opening poin-
ting vertically up for fitting a vacuum flange (DN 50 ISO-KF) or
a corrugated hose. Upon delivery, this opening has been
blanked off with a blank flange including a centering ring, for
the purpose of the protecting the inside of the pump.
The vacuum side of the pump must not be
flanged directly to the vacuum chamber; it must
be flanged via a bellows.
Never suspend the pump on the vacuum flange,
always set up on the standing surface or screw
down.
➡Loosen the screws from the claws and disassemble the
blank flange.
➡Fit the desired component part directly to the inlet opening
using claws; note the centering ring.
Shifting the inlet opening
Depending on the installation situation, the inlet opening may
be shifted to the side or the bottom.
During assembly of component parts do not lay
the pump on the side or the back
➡Disassemble the blank flange (flange cover) at the desired
inlet opening.

cable leads to a wrong direction of rotation.
Pay attention to the markings (U-U/V-V/W-W) at
the pump cable when attaching the pump.
CAUTION
50
53 52
Characteristics for the correct direction of rotation:
➡Open vacuum flange.
➡Switch on pump;
– in case of correct direction of rotation an air flow esca-
pes at the exhaust flange which is decreased after
sealing of the vacuum flange.
– the blank flange cannot be loosened after sucking in at
the vacuum flange.

12
Connecting the sealing gas 8.3 :
➡Unscrew the plug G 1/8" from the pump housing and repla-
ce it by a screw-in small flange.
– If required install a sinter filter.
– Alternatively use a magnetic valve (TVF 005) and
connect it to the control cable X8 (see Section 3.8.
Connecting The Pump To The Electronic Drive Unit TCP
2000).
➡Connect the inert gas line to the sealing gas connection
8.3.
– Generally use dry, oil-free air or pure nitrogen.
3.9. Using Sealing Gas
For applications, where vapors and contaminated gases are
pumped, the pump should be operated with sealing gas at the
shaft feedthrough between the suction chamber and the
bearing chamber on the exhaust side.
This effects the following:
– protection of the lubricant against contamination,
– protection of the bearing when pumping vapors and conta-
minated gases and
The type of sealing gas is dependent on the
process (normally N2 ,alternatively compressed
air, dry and oil-free).
Controlling the sealing gas inlet via magnetic valve:
When the magnetic valve is connected to the
TCP 2000 it opens when a pump rotation speed
exceeds 9000 rpm.
In cases of malfunctions the valve closes auto-
matically.

3.10. Pumping Of Vapors
If condensable vapors are to be pumped, the pump needs to
be operated with the gas ballast on the exhaust side 8.2.
This effects an increase in the gas temperature and a dilution
in the concentration of the process gases.

➡Connect the inert gas line to the gas ballast connection 8.2.
– Generally use dry air or pure nitrogen.
➡Set up the gas ballast throughput to a max. of 20 Nl/min at
the inert gas inlet.
☞
PLEASE NOTE
3.11. Pumping Of Light Or Heavy Gases
When pumping light or heavy gases it is recommended to
operate the pump at the intake side 8.1 with gas ballast:
– In the case of heavy process gases the gas ballast effects
cooling and a dilution in concentration.
- In the case of lighter gases the gas ballast operates as a
carrier gas which promotes pumping of the process
medium.
If gases other than air or nitrogen are used for
the gas ballast, please discuss such plans with
Pfeiffer Vacuum first.
The gas ballast reduces the volume flow rate
and increase the final pressure correspondingly
to the admitted quantity of gas ballast.

4.1. Before Switching On The Pump
Lubricant must be refilled in the exhaust side
bearing chamber already after 1000 operating
hours depending on the use of the pump. The
filling level is monitored and leads to switching
off the pump when falling below the minimum
mark.
➡Check the lubricant level before starting the pump.
➡Before switching on the pump check that all lines have
been correctly connected.
Shut-off valves in the exhaust line should be
activated so that they open either before or
simultaneously with the start of the pumps.
Pump rotors rotate at high speed. When the
high vacuum flange is open there is a
danger of injury and of damage to the pump
caused by objects falling into the pump.
Therefore never operate the pump with open
high vacuum flange!
➡Open the cooling water supply and adjust the flow until at
least one green LED at the cooling water monitor lights up.
4.2. Switching The Pump ON
Details regarding the switching on of the pump and after a
malfunction has occurred are contained in Operating Instruc-
tions PU 0056 BN for the Electronic Drive Unit TCP2000.
➡Switch on pump via the connecting terminal X4.14
➡Bring pump to operating temperature before process start
(approx. 10 min) to prevent condensation.
When switching on for the first time or after a
change of lubricant, the contacts for monitoring
the lubricating pump can open as a result of
degassification. In such cases, as for other
malfunctions, the electronic drive unit switches
off the pump.

HINWEIS
4. Operations
4.2.1 Motor Temperature Monitoring
An automatic temperature control controls the following
units:
Motor temperature
For motor temperature monitoring there are two limiting
values:
−WWaarrnniinngg::
A motor temperature > 75°C results in a lowering the motor
in order to avoid an overheating of the motor.
−EErrrroorr::
A motor temperature > 85°C --> results in switching off the
pump and an error message (E.EF) is displayed at the
display and control unit at the TCP.
4.3. Gas Type Dependent Operations
Where high level gas loads and rotation speeds are involved,
the resulting friction subjects the rotor to the effect of great
heat. To avoid over-heating, a power rotation speed charac-
teristic line is implemented in the TCP 2000; this ensures that
where maximum gas loads are involved, the pump will ope-
rate at any rotation speed without the danger of damage
arising. The maximum power is dependent on the type of gas
and consider only nitrogen, respectively air and lighter gases.
Max. permissible gas loads:
−Molecular mass < 40 (e.g. Argon) ≤1000 sccm
−Molecular mass > 40 in exceptional cases with gas ballast.
Pumping gases with molecular mass ≥40 can
cause damage to the pump. Before pumping
such gas types please contact the
manufacturer.
WARNING

4.5. Preparation For Transport And
Shutting Down The Pump For
Longer Periods
Empty cooling water circuit before transporting
and stocking the pump to avoid frost damage.
Storage temperature range: - 25 °C ... + 55 °C
Transport temperature range: - 25 °C ... + 70 °C
➡Do not disconnect the Electronic Drive Unit TCP 2000 from
the mains until attainment of 0 Hz rotation speed.
➡Unplug cooling water and empty water chambers; for this
admit compressed air (2 ... 5 bar) at the water inlet line 80.
Make sure the hose of the outlet line 81 is open and unalig-
ned.
➡Drain off the lubricant or dismantle both lubricant
reservoirs from the pump housing and empty any residual
lubricant into a suitable vessel; (see Section 6.2.).
The Shelf-life of lubricant F3 is 4 years when
storing in dry areas and closed original
packaging.
☞
PLEASE NOTE
CAUTION
To avoid condensation in the pump, vapours
should only be pumped off when the pump is
warm and with gas ballast valve 8.2 open.
When the process has been completed, allow
the pump to continue running for about 30 minu-
tes with open gas ballast valve for operating
fluid regeneration purposes.
CAUTION
4.4. Switching The Pump OFF
Details regarding the switching off of the pump are
contained in Operating Instructions PT 0087 BN for the
Electronic Drive Unit TCP 2000.
When switching off the pump or in case of
malfunctions shut off the suction line immediate-
ly to prevent the vacuum chamber being ventila-
ted via the backing pump.
➡Switch off pump via the connecting terminal X4.14
➡Close the fore-vacuum safety valve (if fitted).
➡Disconnect the Electronic Drive Unit TCP 2000 from the
mains not until the pump rotor is at rest and only then
disconnect the connecting cable pump/TCP.
CAUTION
It is recommended to flush the pump with an inert gas (e.g.
Nitrogen) before shutting down the pump for longer periods.
➡Vent pump via the vacuum flange with nitrogen or dry air.
➡Block off the pump on the intake side and at the exhaust
flange by using a blank flanges.
If the pump has been shut down for 33yyeeaarrss, the
bearing must be changed (please contact

6.1. Precautionary Measures During
Maintenance Work
No liability for personal injury nor material
damage will be accepted for damages and
operational interruptions which have been
caused by improper maintenance; in addition,
all guarantees become invalid.
Whenever working on the pump ensure the elec-
tronic drive unit is disconnected from the mains
supply.
If necessary, remove pump from the system for
inspection.
➡When working on the pump, always secure pump against
being switched on.
➡When working with synthetic lubricants or with
substances which are toxic or are contaminated with
corrosive gases, the relevant precautions must be
observed.
➡Clean pump parts only with alcohols. Do not use other
solvents.
Do not allow any liquids to enter into the inside
chamber of the pump.
This can damage the rotor blades!
6.2. Replacing The Lubricant
Usual intervals for lubricant replacements:
1... 2 years depending on the operating conditions.
The intervals for lubricant replacement are governed by the
operating conditions. Influential factors are operating tempe-
rature and the type of process medium.
During maintenance and repair work, process
related toxic gases and vapours can escape
from the lubricant which may become comtani-
mated with harmful substances (radioactive,
chemical etc.).
Please request safety instruction data sheets
for lubricants from Pfeiffer Vacuum.

6. Maintenance
Changing the lubricant
➡Allow the pump to cool to a safe temperature.
➡Switch off and vent pump if lubricant is to be replenished.
➡Unscrew lubricant drain screws 32 on both sides (valid for
pumps with revision index “E”) and drain lubricant;
otherwise dismantle lubricant reservoirs and pour out
lubricant.
➡Screw in lubricant drain screws 32.
Cleaning the lubricant reservoir
➡Dismantle both lubricant reservoirs 16 by unscrewing each
four screws 17 on the underside of the pump.
➡Detach lubricant reservoir 16 horizontally from the pump
casing and drain off any residual lubricant into a suitable
vessel.
➡If necessary remove the strainers from the lubricant reser-
voir and clean.
➡After cleaning, refit the strainers and screw on lubricant
reservoirs.
➡During strong contamination of the lubricant, exchange
lubricant reservoir completely.

If ‘’F3’’ is heated above 300°C, toxic vapours
which can harm the respiratory tract are
emitted. Do not allow ‘’F3’’ to come into contact
with tobacco products (danger of poisoning
when ignited). The precautions necessary in
the handling of chemicals must be observed.
WARNING
Before first-time starting and after a lubricant
change, the amount of lubricant is approximate-
ly 24ml.
The filling level range shown in the illustration
("min./max.") should never be exceeded nor
undershot.
Please contact your local Pfeiffer Vacuum Service for all
other maintenance and service work.
CAUTION
Filling in the lubricant
Only fill the lubricant reservoirs of the pump in
the horizontal position. Do not fill when the
pump is running and not in evacuated condition.
➡Unscrew both lubricant filler screws 31, taking care with
the sealing.
➡Slowly fill in 24 ml of the accompanying lubricant into each
lubricant reservoir.
➡Screw back in lubricant filler screws 31 with the sealing.
➡During operations or at pump still stand check the
lubricant level on both sight glasses; the permissible level
is shown in the illustration.
➡In non-stop operations check the lubricant monthly, on
both sight glasses 9 after each switch-on.
