Nuclear Power Plants Nuclear power plants have a demand for constant radiation monitoring with their air sampling systems requiring a vacuum pump to collect samples. This requires a very reliable compressor and also one that does not introduce contaminants into the sample being collected. Senior Aerospace’s Hermetic Compressors/Hermetic Vacuum Pumps For the production of Silicon Sapphire ingots used to make wafers, furnace manufacturers are faced with the challenge of growing larger high purity crystals. As these furnaces are running 24/7, a very robust pump used to circulate helium throughout the process chambers is needed without introducing any particulate contamination to maintain the purity of the crystal growth, as well as improve the yields. To solve this problem, Senior has a bellows compressor/bellows vacuum pump that uses a “welded bellows” as the pumping mechanism. Since all the “wetted surfaces” are of stainless steel construction, there is zero contamination

Oil Drilling Compensators The days of setting up a drilling rig and boring straight down into the earth, hoping to find oil, is now over. This hit or miss method is far too costly, which has motivated the oil exploration community to employ sophisticated sensors and drilling apparatus that takes most of the guesswork out of finding oil. Seismic tools locate oil pools and sophisticated drilling tools incorporate steer able systems with real time imaging to minimize the drilling time. These special drilling tools can be controlled from the surface and made to drill long distances, horizontally if required. Senior Aerospace products are an integral part of these sophisticated drilling tools providing volume compensation with a clear advantage of better frequency response from the bellows by replacing “piston and spring” technology.

solution is a 
of no out-gassing, which would occur with a traditional piston drive pump with elastomeric seals. During the manufacturing acceptance test procedures for our pumps, they are run-in for 50 hours, which puts over 10 million cycles on the unit to ensure it will meet infinite life in the field.
