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 required in its operation. This liquid can be water, essential oil or any various other 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 has been through a distillation process to reduce its vapor pressure. These vacuum pumps oil-free air compress possess an ultimate vacuum, occasionally known as “blank off” vacuum, of 0.010 Torr (10 microns, 1 x 10-2 Torr or 
0.0133 mbar).
