A liquid ring Vakuum Pumpe vacuum pump is easy to operate and is utilized in 
several applications across various industries. A liquid ring pump works together with a sealant needed in its operation. This liquid can be water, essential oil or any additional solvent which is rotated by an impeller within the casing of the pump.
The typical oil used in a sizable rotary piston vacuum pump is a mineral oil that has been through a distillation process to reduce its vapor pressure. These vacuum pumps have an ultimate vacuum, sometimes known as “blank off” vacuum, of 0.010 Torr (10 microns, 1 x 10-2 Torr or 0.0133 mbar).
