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 33 yyeeaarrss, the
bearing must be changed (please contact
Pfeiffer Vacuum Service).
