Vacuum Pumps

vakuum pumpe

A liquid ring vacuum pump is easy to operate and is used in several applications across various industries. A liquid ring pump works with a sealant required in its operation. This liquid can be water, oil or any other 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 has been through a distillation process to reduce its vapor pressure. These vacuum pumps have an ultimate vacuum, sometimes called "blank off" vacuum, of 0.010 Torr (10 microns, 1 x 10-2 Torr or 0.0133 mbar).
