A Vakuum Pumpe 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 with a sealant required in its procedure. This liquid can be water, oil or any additional solvent which is usually 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 called “blank off” vacuum, of 0.010 Torr (10 microns, 1 x 10-2 Torr or 0.0133 mbar).
