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