A liquid band vacuum pump is easy to operate and is used in several applications across various industries. A liquid band pump works with a sealant required in its operation. This liquid could be water, essential oil or any additional solvent which is certainly rotated by an Vakuum Pumpe impeller within the casing of the pump.
The typical oil used in a large rotary piston vacuum pump is a mineral oil that is through a distillation process to reduce its vapor pressure. These vacuum pumps have an ultimate vacuum, occasionally called “blank off” vacuum, of 0.010 Torr (10 microns, 1 x 10-2 Torr or 0.0133 mbar).
