A liquid band vacuum pump is simple to operate and can be used in several applications oil-free air compress across various industries. A liquid band pump works together with a sealant necessary in its operation. This liquid can be water, essential oil or any additional solvent which can be rotated by an impeller within the casing of the pump.

The typical oil found in a large rotary piston vacuum pump is a mineral oil that is through a distillation process to lessen its vapor pressure. These vacuum pumps have an ultimate vacuum, occasionally known as “blank off” vacuum, of 0.010 Torr (10 microns, 1 x 10-2 Torr or 0.0133 mbar).
