Mounting instructions VacuStar WR 2500 / WR 3100 / WR 4000
Design and function

Drive
The VacuStar WR can be powered via:
Articulated shaft
V-belt
Flexible coupling
See page 35.
Process water circulation and cell
ventilation
In addition to the drive and the suction and pressure lines, other
components are required to operate a liquid ring pump (see
page 24, Fig. 8).
Water circulation with reservoir and radiator.
The air flowing through the VacuStar WR absorbs humidity
from the liquid ring, and is 100% saturated when it exits.
Only the water drops are separated in the reservoir. The
steam component is dissipated to the environment.
Fig. 7: Process water delivery
Fig. 7 shows the process water delivery from the reservoir for an
intake volume flow of 100 m³/h as a function of intake pressure and
process water temperature.
Typical process water loss calculation:
Type : VacuStar WR 3100
Intake pressure: 400 mbar
Intake volume flow according to Tab. 3: 2427 m³/h
Process water output temperature: 50 °C
Water loss for intake pressure and
process water outlet temperature according to Fig. 7:
2.1 l/h per 100 m³/h intake air
