Establish 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
3. Implement measures to counteract the backflow of operating fluids or condensate from the fore-

5.5 Cooling water connection
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
► Wear protective equipment, e.g., safety goggles and gloves.

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).
