When testing blowers, we utilize a pump again, to duplicate field applications. All test equipment used in the vacuum system area is factory approved and calibrated regularly to ANSI standards to maintains accuracy.
K+S Services utilizes a number of various pieces of testing equipment to fully test all vacuum products. We use the Varian 959 Porta-Test Leak Detector which has a minimum detectable signal / sensitivity of 2 x 10-8 atm cc/sec (helium) sniffing mode to detect leaks in accordance with AVS standard 2.1 .We also use the “SenTorr” gauge controller in conjunction with the “524 Cold Cathode Ionization” gauge to measure vacuum down to 1 x 10-8 Torr. We additionally utilize the “ConvecTorr” gauge to test 1 x 10-3 Torr to atmosphere.

The basic use for a vacuum pump is to remove gas molecules from a sealed chamber or designated area which is essentially to remove atmosphere. The most common molecules contained in earth’s atmosphere are typically nitrogen, carbon dioxide, oxygen, and various common contaminants.
The process of removing of the molecules from the chamber or area continues until the designated level of required vacuum is realized. Depending on the specific level of vacuum your application requires it may be necessary to utilize a series of vacuum pumps to effectively achieve this level.
The pumps are what is called momentum transfer or also molecular pumps and are the most commonly used and effective means for achieving high vacuums. The most typical configuration involves using a single or a pair of positive displacement pumps in combination with a Diffusion/Molecular pump to realize high vacuum.
The diffusion pump is recognized as one of the earliest types uses as well as the most reliable for creating a high vacuum. A diffusion pump cannot begin working in full atmosphere which is why you will see a positive displacement pump being used to get into low vacuum and then the diffusion pump begins working from there to achieve higher vacuum levels.
