5.3 Connecting the fore-vacuum side
WARNING
Danger to life from poisoning where toxic process media leak from damaged connections
Sudden twisting of the turbopump in the event of a fault causes fittings to accelerate. There is the risk
of damaging on-site connections (e.g., fore-vacuum line) and resulting leaks. This results in leakage
of process media. In processes involving toxic media, there is a risk of injury and danger to life due to
poisoning.
► Keep masses connected to the turbopump as low as possible.
► Use flexible lines to connect to the turbopump where necessary.
Suitable backing pump
Use the turbopump only in combination with a suitable backing pump that can deliver up to
the required maximum fore-vacuum pressure. To achieve the fore-vacuum pressure, use a
suitable vacuum pump or a pumping station from the Pfeiffer Vacuum range.
In this case, the backing pump is also controlled directly via the turbopump electronic drive
unit interfaces (e.g., relay box or connection cable).

Establishing the fore-vacuum connection
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 16 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.
5.4 Cooling water connection
The HiPace 300 turbopumps use water cooling as standard.
