5.3 Operating Liquid Settings
The machine cannot operate without an operating liquid system. The actual scope of delivery is al-
ways contractually agreed upon.
The condition of both the operating liquid and the conveyed media depend on the physical condi-
tions pressure and temperature.
At a very low pressures and sufficiently high temperatures the operating liquid can locally transfer
into the vapor phase, creating bubbles within the operating liquid. This process is called “cavitation”
and may deteriorate the machine and its performance, see
Preventing Cavitation [

Recommended operating liquid (water) settings at various inlet pressures:
