A liquid band vacuum pump is simple to operate and is used in several applications across various industries. A liquid band pump works with a sealant required in its procedure. 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 big rotary piston vacuum pump is a mineral oil that is oil-free air compress through a distillation process to lessen 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).
