Vacuum pumps have recently undergone substantial advances in terms of reliability, performance, quiet operation, and energy economy.
To assist you in selecting the best type of equipment for your application, here is a brief overview of the operating principles and current developments in the four main categories of industrial vacuum pump.

Operating on the simple principle of centrifugal force acting on an eccentrically mounted rotor with radially movable blades, this tried and tested technology has been subject to a host of design innovations to improve performance and reduce total operational costs. Compared with earlier generations, power demand at the same volume flow is now about 15 per cent lower. In general, the latest units are more compact, with vibration levels that are 3 to 5 dB(A) quieter than their predecessors. They can also now operate at lower temperatures, which protects oil consistency and extends service life as well as maintenance intervals. The reliability of these ubiquitous machines is attributable to their basic, sturdy construction and good oil retention at all operating pressures. In the latest designs, the pumps incorporate internal injection channels. This reduces the number of gaskets and the amount of external piping required. In some cases, the number of components has been reduced by as much as 20 per cent, further minimising the risk of leaks and subsequent failures. Capable of an ultimate pressure between 0.1 and 0.5 mbar, rotary vane vacuum pumps are suitable for packaging, woodworking, plastics, paper and printing, material handling and other demanding applications.
