which is then expelled with the pumped air through the outlet. As the working fluid leaves the
pump, fresh fluid is added to it.
After pre-filling, the 2BV pumps can be started and automatically draw up the process
liquid. This requires sufficient process fluid to be available when the pump starts.
3.1.3.2 Separator and partial recirculation
This delivery method helps to save some water. Part of the working fluid settles in the
separator and flows directly to the pump, without any cooling. In this case, part of the liquid is lost
to evaporation and is replaced with fresh liquid. All connection sets are supplied with the
separators.

The separator is designed to separate the liquid from the pumped gas. It allows the
process fluid to be recycled, which significantly reduces its consumption (see Figure 4). The
separator is supplied as an accessory with all necessary connections.
If cavitation protection is required, a safety valve is connected between the separator and
the pump casing.
3.1.5 Check valve
To prevent backflow and liquid from entering the vacuum network, we recommend
installing a check valve on the suction side.
