    • Design And Testing Of Dual Seal Series Arrangements For Pressurized Barrier Fluid 
      Lavelle, Kenneth E.; Key, William E.; Holman, Al C. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
      Dual mechanical seals are operated on pressurized barrier fluid systems when the pump product properties do not support reliable single seal operation. This provides added protection against environmental release of the ...
    • Development Of A Noncontacting Seal For Gas/Liquid Applications Using Wavy Face Technology 
      Young, Lionel A.; Key, William E.; Grace, Ronald L. (Texas A&M University. Turbomachinery Laboratories, 1996)
      A seal has been developed and tested that incorporates a circumferential wave pattern with a sealing dam formed on a SiC face, using a proprietary process. When run against a flat carbon face, laboratory tests show that ...
    • Improved Mechanical Seal Design Through Mathematical Modelling 
      Salant, Richard F.; Key, William E. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      The mechanical seal manufacturer can now offer the user new seal designs quickly and efficiently, and can respond to trouble shooting requests rapidly, through the use of modern, computerized, seal design techniques. In ...
    • Improvement Of A High Temperature Bellows Seal 
      Key, William E.; Grace, Ronald L.; Lavelle, Kenneth E.; Young, Lionel A.; Wang, George; Holman, Al (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
      An Inconel 718 metal bellows seal has been developed to meet the demands for high temperature applications in corrosive media such as high Sulphur bearing crude oil. Finite element analysis was used to develop concepts ...
    • Magnetic Fluid Seal System For Control Of Pump Fugitive Emissions 
      Key, William E.; Young, Lionel A.; Mraz, Will B.; McMahan, Paul; Black, Thomas J. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
      Pump fugitive emissions can now be controlled to near zero levels by the use of a simplified dual seal system. A magnetic fluid secondary seal traps any vapors that leak past the primary mechanical seal. This arrangement ...
    • Tandem Seals For Near Zero Hydrocarbon Emissions 
      Key, William E.; Wang, George; Lavelle, Kenneth E. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
      More stringent regulatory limits are being placed on gaseous emissions from pumps handling hydrocarbon fluids. For example, new pumps in the Los Angeles Basin are required to have ear zero emissions. The EPA is proposing ...
