HABERG liquid ring vacuum pumps (LRVP) are of the double stage displacement type. The only movable parts are the shaft and the vane wheel impellers. They do not touch the stationary pump parts. Both shaft ends run in anti-friction bearings. For sealing, mechanical seals are applied.
A liquid ring rotating in the working chamber of the pump, eccentrically to the shaft, takes up to the drive power delivered to the vane wheel impellers and transfers it as compression power to the gas to be compressed.
Haberg LRVPs are adaptable to most duties, with appropriate selection of materials and service liquid. Reliable operation with minimum maintenance. Low noise and vibration levels.
Using water with temperature of 15 degree Celcius as service liquid and a pressure of 1013 mbar at the discharge branch, the lowest suction pressure achievable is 33 mbar.
Standard material of construction in cast iron body and stainless steel impeller with fully stainless steel material available by request.
