A liquid band vacuum pump is easy to operate and is utilized in a number of applications across various industries. A liquid band pump works together with a sealant necessary in its procedure. This liquid can be water, essential oil or any other solvent which is usually rotated by an scroll air compressor impeller within the casing of the pump.
The typical oil found in a huge 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).
