High and Low Vacuum
Up to 25mm Hg absolute, and higher (with other service liquids). Pumps are designed
to operate at low vacuums.
Long life and low maintenance cost
The impeller and shaft are the only moving parts. The impellers have no contact with
the casing. There are no sliding vanes or valves.
Vibration-free and noiseless operation
Rugged construction and the absense of reciprocating parts ensure vibration-free and
Non-pulsating gas flow
No internal lubrication
Liquid and vapour handling
Liquid ring vacuum pumps are capable of handling large quantities of vapour. Small
amounts of liquid drawn in from the system will also pass through the pump without causing
Low starting torque
Different service liquids may be used
Materials of construction
Pumps can be constructed from a wide range of materials to suit corrosive conditions.
Delivery of absolutely oil-free air
When unit is used as a compressor.
