In the creation of a high vacuum, oil-free membrane pumps provide the necessary fore-vacuum and turbo pumps perform the final compression. High-quality metal connecting components provide for reliable and permanently leak-proof connections in this process.
For more than half a century, Vacuubrand GmbH + CO KG, located in the North Baden city of Wertheim, has specialised in technology for the generation of vacuums. The product spectrum includes, for example, rotary vane pumps, oil-free membrane pumps and entire vacuum pump stands. Vacuum pumps are used in laboratories, industrial applications or for leak detection, to name just a few.
Vacuum has to be of high quality
For every demanding vacuum process, Vacuubrand requires quality down to the smallest detail. This also applies to the pneumatic connection components, for which the company uses connecting components from Eisele Pneumatics GmbH + Co KG in Waiblingen. They are also included as OEM parts in the CAD construction kit of the vacuum specialist, so that the design engineers have easy access to the Eisele components for all Vacuubrand products.
To facilitate design
Eisele provides detailed documentation of its components, which of course considerably facilitates the design engineer’s selection and use of the right threaded connections. Thanks to the broad product assortment, virtually all required components are available from one source. The high-quality parts from the Eisele modular kit can easily be modified to create specific customer solutions, for example by turning an additional face or adding a threaded joint. Eisele is always the right address when it comes to implementing special customised solutions. Currently, the company has 2,000 of these to offer.
Special requirements fulfilled
The sealing requirements for vacuum applications are much higher than in normal pneumatic applications, in which a certain leakage rate, although not desirable, can at least be tolerated. In vacuum applications, even small leaks would endanger the entire process, since the required end vacuum could not be achieved reliably and stably. That is exactly why the connections and fittings have to fulfil high requirements. A clear advantage of Eisele quality becomes obvious here: All surfaces are extremely smooth and free of burrs, and all sealing surfaces feature a very high degree of plane parallelism, which prevents the occurrence of incorrect positions during tightening. Another decisive advantage of the Eisele system is that the hose connections are threaded instead of plug-in connections. Otherwise, the connections of the external hoses would be too easy to disconnect.
