A liquid ring Vakuum Pumpe vacuum pump is easy to operate and can be used in a number of applications across various industries. A liquid band 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 found in a sizable rotary piston vacuum pump is a mineral oil that has been through a distillation process to lessen its vapor pressure. These vacuum pumps possess an ultimate vacuum, occasionally called “blank off” vacuum, of 0.010 Torr (10 microns, 1 x 10-2 Torr or 0.0133 mbar).
