Proper Use

Ambient conditions
The turbomolecular pump needs to be installed in compliance
with the following ambient conditions:

– The Turbomolecular Pumps TMH 521 P/TMU 521 P may
only be used for the purpose of generating vacuum.
– The turbopumps may only be used to pump those media
against which they are chemically resistant. For other
media the operator is required to qualify the pumps for the
processes involved.
– If the process produces dust, the maintenance intervals
must be specified accordingly and sealing gas must be
used.
If the pump is to be operated with more than 50% of the
permissible gas load then sealing gas should be used to
ensure rotor cooling.
– The turbopump must be connected to a backing pump in
accordance with Section 3.3.
– Only Pfeiffer Vacuum power supplies may be used to
operate the TC 600. The use of other power supplies
requires the express agreement of the manufacturer and
equalisation with the valid specification.
– Without the cover plate for the TC 600 the pumps may only
be operated providing the ambient conditions in
compliance with Protection Type IP 30 are observed.

2.3. Scope Of Delivery

The following is regarded, inter alia, as improper:
– The pumping of explosive or corrosive gases.
– Operating the pumps in areas where there is a danger of
explosion.
– Operating the pumps in areas where there is a danger of
radioactivity.
– The pumping of gases and vapours which attack the materials of the pumps.
– The pumping of corrosive gases without sealing gas.
– The pumping of condensating vapours.
– Operations involving impermissibly high levels of gas
loads.
– Operations with impermissibly high fore-vacuum pressure.
– Operations with improper gas modes.
– Operations involving too high levels of heat radiation

WARNING

In case the rotor blocks suddenly, torque levels
up to 6690 Nm can occur which need to be
absorbed by the system and the high vacuum
flange.

– If the turbopump is to be operated with the DCU 001 or
HPU 001, the remote plug 8d (please see Section 2.1.) on
the TC 600 should be disconnected and then proceed in
accordance with the corresponding operating instructions.
– The maximum permissible rotor temperature of the pump is
90 °C. If the vacuum chamber or parts in the vacuum
chamber are heated, the values stated in the technical
data relating to the level of heat which may be radiated
into the pump must not be exceeded. If necessary, suitable
shielding must be fitted in the vacuum chamber before the
turbopump (constructional suggestions available on
request).
_ The temperature of the high vacuum flange must not
exceed 120 °C.
– Only remove the blank flange from the high and forevacuum side immediately before connection.
– On Turbopumps TMH 521 P/TMU 521 P the lubricant
reservoir is already fitted and filled.
– Where magnetic fields of > 5.0 mT are involved suitable
shielding must be provided (available on request).
– If the pump is baked out, the heating sleeve and the body
of the pump must be insulated to prevent burns from
accidental contact.
– For operating the pump air or water cooling is necessary.

4. Operations
4.1. Before Switching ON

4.2. Switching ON

Sections 4.1. to 4.3. refer only to operating the pump in its
condition on delivery, without the DCU operating unit. The
bridges ”venting release”, ”motor, TMP ON” and ”pumping
station ON” are fitted in the remote control plug.

➡ Switch on the turbopump with switch S1 on the power
supply.
– With air cooling the cooling fan is also switched on via
Electronic Drive Unit TC 600.
– Once the self test has been successfully completed on the
TC 600 (duration approximately 15 seconds), both the
turbopump and the backing pump (if connected) begin
operating.

WARNING

CAUTION

Turbopump 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.
Take care when pumping hazardous gases and
observe the safety precautions of the gas manufacturer.

➡ With sealing gas: Open the sealing gas supply.
➡ With water cooling: Open cooling water supply and check
flow.
➡ With connecting cable 8a (see Section 11. Accessories)
connect the TC 600 and Power Supply TPS 300 on X2
(please see Section 3.8.).

These settings can only be altered via Serial Interface RS 485
(DCU, HPU or PC); please refer to the respective operating
instructions.

4.3. Switching OFF And Venting
Before coming to rest after switching off, the turbopump must
be vented in order to prevent contamination.
➡ Close the fore-vacuum.
➡ Switch off both turbopump and backing pump with switch
S1 on the power supply.
➡ Venting
There are three possibilities to vent turbopump:
– Manual venting with the use of the venting screw
(status on delivery).
– Venting with the venting valve which is selectable
via the remote control (please see Section 4.7.), or via
the DCU or HPU (see respective operating instructions).
– Venting in two stages when the vacuum chamber
should be vented as quickly as possible. First stage:
venting with a pressure increase rate of 15 mbar/s for
20 seconds.
Second stage: venting with an optionally large venting
valve.
The valve cross-section for a venting rate of 15 mbar/s
must be compatible with the size of the vacuum chamber.
Where small vacuum chambers are involved, the
Pfeiffer Vacuum Venting Valve TVF 005 can be used for
first stage venting.
➡ Shut off water supply.
15

Water cooling is required if the pumps are to be
operated with gas load.

CAUTION

Gas type characteristic line

Power

4.4. 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
characteristic line is implemented in the TC 600; this ensures
that where maximum gas loads are involved, the pump will
operate at any rotation speed without the danger of damage
arising.
The maximum power is dependent on the type of gas. Two
characteristic lines are available for any type of gas in order
to fully exploit the power potential of the pump:
– "Gas-Mode 0" for gases with molecular mass ≥ 40 as, for
example, Argon;
– "Gas-Mode 1" for all lighter gases.

WARNING

Pumping gases with molecular mass ≥ 40 with
the incorrect gas mode can cause damage to
the pump.When pumping noble gases heavier
then Argon it can come to the destruction of the
pump. Please contact the manufacturer before
using such gases.

D-C = Gas mode «0»
B-A = Gas mode «1»

Frequency

WARNING

If aggressive or hazardous gases are pumped
there is a danger of personal injury resulting
from coming into contact with process gases.
Before removing a turbopump from the system,
first:
–
Vent the turbopump with a neutral gas or

dry air.
– Ensure that there is no residual process gas in the system
nor in the feeder lines.
If the turbopump is to be shut down for more than a year:
➡ Remove turbopump from the system.
➡ Change the lubricant reservoir (see Section 7.1.).

For the vertex of the power characteristic line please refer to
Section 9. Technical Data.

There can be types of pump whereby there is no
differentiation between the two ”gas modes”
settings.

Lubricant TL 011 should not be used when there
have been no operations for 3 years.

➡ Close the high vacuum flange and evacuate the turbopump
via the fore-vacuum flange.
➡ Vent turbopump via the venting connection with nitrogen
or dry air.
➡ Close fore-vacuum and venting connection by blank
flanging.
➡ Place the pump vertically on its rubber feet.
➡ The pump must be stored in buildings within a temperature
range of -25 °C to +55 °C.
➡ In rooms with moist or aggressive atmospheres, the turbopump must be air-sealed in a plastic bag together with a
bag of dessicant, e.g silicagel.
PLEASE NOTE

4.5. Shutting Down For Longer Periods

CAUTION

Maximum power is applied when the pump starts in order to
limit the time required. Once the set rotation speed is
attained, switching to the selected power characteristic line
is automatic. If the gas dependent maximum power is exceeded, the rotation speed is reduced until equilibrium between
the permissible power and gas friction is attained.
The power limitation serves to protect the pump against thermal over-loading. In order to avoid rotation speed fluctuations
it is recommended to set, in rotation speed setting mode, the
equilibrium frequency or a somewhat lower frequency.

Run up

C

Works setting: “Gas mode 0”
➡ Set the applicable gas mode on the TC 600 via the
DCU/HPU (please refer to the respective operating instructions.

If the pump has been shut down for
3 years, the bearing must be changed (please
contact Pfeiffer Vacuum Service).

4.6. Operations With The
DCU 001, DCU 300 or HPU 001
Operations with the DCU 001, DCU 300 or HPU 001 should be
carried out in accordance with the relevant Operating
Instructions:
PM 0477 BN (DCU description)
PM 0547 BN (Operating the pump with the DCU)
