A liquid ring vacuum pump is easy to operate and is used in Vakuum Pumpe several applications across various industries. A liquid band pump works together with a sealant necessary in its procedure. This liquid can be water, oil or any other solvent which is certainly 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 process to reduce 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).
