A liquid band vacuum pump is easy to operate and is utilized in several applications across various industries. A liquid ring pump works with a sealant required in its procedure. This liquid could be water, essential oil or any additional solvent which is rotated by an 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 lessen its vapor pressure. These vacuum pumps possess an ultimate vacuum, sometimes known as “blank off” vacuum, of 0.010 Torr (10 Vakuum Pumpe microns, 1 x 10-2 Torr or 0.0133 mbar).
