Procedure
1. With rigid pipe connections, include bellows to attenuate external vibrations.
2. Install a fore-vacuum connection with small flange components, e.g. connection elements and
pipe components DN 40 ISO-KF from the Pfeiffer Vacuum Components Shop.
3. Implement measures to counteract the backflow of operating fluids or condensate from the fore-
vacuum area.
4. Observe the information in the operating instructions of the backup pump or pumping station when
connecting and operating it.
5.5 Connecting the cooling water supply
WARNING
Risk of scalding from suddenly escaping hot cooling water
The turbopump water connections are open to both sides. When connecting the cooling water supply,
there is a risk of scalding from suddenly escaping, hot cooling water at over pressure.
►
Prior to installation, ensure that pressure is discharged from the cooling water system, and that it
is cooled down.
►
Wear protective equipment, e.g., safety goggles and gloves.
