A liquid band vacuum pump is simple to operate and can be used in several applications across various industries. A liquid ring pump works together with a sealant required in its operation. This liquid could be water, oil or any various other solvent which is usually 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 is through a distillation process to lessen its vapor screw air compressor pressure. These vacuum pumps possess an ultimate vacuum, sometimes known as “blank off” vacuum, of 0.010 Torr (10 microns, 1 x 10-2 Torr or 0.0133 mbar).
