Methods for Handling/Removing Water and Condensable Vapors in Oil Sealed Vacuum Pumps

Oil sealed vacuum pumps such as vane and piston pumps can tolerate a certain amount of water and other condensable vapors such as alcohols, acetone, and solvents. For the integrity of the sealant oils, and to achieve a good vacuum (lower than the vapor pressure of the liquid), it is best to prevent the condensables from entering the oil sealed vacuum pumps or removing them after they do enter the vacuum pump. The following discusses various methods for this removal and mostly refers to the condensate as water. The discussion of water is also applicable to other vapors and liquids, especially ones having a vapor pressure close to or higher than water. Trapping and filtering condensable vapors upstream of the...

Helium Leak Detector Selection: A Discussion

Helium leak detectors (HLDers) are single gas mass spectrometer devices. They are tuned to detect the presence of helium and also have the capability of measuring a leak or verifying the absence of a leak to a given value. Helium is used as a tracer gas because it is a very small atom, is an inert gas, is relatively inexpensive, and is present in ambient atmosphere air in extremely small values (mid range 1-07). The "leak" is most commonly measured in atmospheric cubic centimeters per second (atm cc/sec). This value will be in Torr or Millibar (mbar). There is 760 Torr or 760 mm of Hg per atmosphere. There is 1013 mbar or 1.0 bar per atmosphere. The described leaks...

Who bought who? Whose on first?

Yes, the vacuum pump world has been confusing recently. The short story is there has been much consolidation, name changing, and company purchases within the last 10 years. Many of the purchased companies are companies with 60 to a 100-year history. Brooks Automation bought CTI (and MKS). Edwards Vacuum bought the Seiko Seiki Vacuum Company a few years back. At first, the Seiko Seiki Pumps (STP) still were referenced as Seiko Seiki, but since the last few years, they now all state Edwards. They are still manufactured in Japan. Edwards bought Stokes Vacuum (and subsequently cancelled  much of the Stokes line). BOC Edwards is now known as Edwards Vacuum as BOC sold the vacuum pump line. Gardner Denver, a Thomas...
