Vacuum Pumps

Piston type vacuum pumps and compressors are being used where oil-free air is a must. The oil free character of the pump is a guaranty of low maintenance costs.

Piston pumps are used for most large scale vacuum applications. These pumps have a sliding sleeve through which the gas enters, then drawn into a cylindrical chamber and exhausted by a rocking piston plunger.

Liquid Ring Vacuum Pump Working Principle. The vacuum pump consisting an impeller which is located eccentric to the cylinder body(Vacuum pump housing). Vacuum is created in the vacuum pump by using a liquid seal.

Vacuum Pumps The installation of a Variable Speed Drive (VSD), sometimes called a variable frequency drive, usually saves between 50 and 65% in electricity costs with the same or better regulation of vacuum. The range of energy savings can be from 30 to 80 percent. They can be adapted to blower or in some cases rotary vane type vacuum pumps.

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.

For many years now Roots vacuum pumps have been well established in the area of vacuum technology. In combination with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.
