      Many of the corrosion-related problems encountered in pumps during their useful lives are reviewed. Seven forms of corrosion are discussed with guidelines given that could mitigate pump damage if proper consideration were ...
    • Design And Operation Refinement Of A Multistage Light Hydrocarbon Pump 

      Laplant, Kenneth R.; Rutan, Charles R. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
      One of the most critical pieces of equipment in an Olefin plant is the ethylene product pump. The challenge of designing a vertical process pump that will deliver a high vapor pressure liquid with poor lubricating qualities ...
    • Design Considerations And Application Guidelines For Pumping Liquids With Entrained Gas Using Open Impeller Centrifugal Pumps 

      Cappellino, Charles A.; Roll, Daniel R.; Wilson, George (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
      The proper selection of a centrifugal pump for liquid and gas (two phase) mixtures, is highly dependent on the amount of gas and the characteristics of the mixture. The presence of entrained gases will reduce the output ...
    • Development And Qualification Of A Magnetically Coupled Process Pump For API 610 7th Edition Services 

      Heald, Charles C.; Behnke, Paul W.; Gussert, Richard F. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
      A magnetically coupled process pump configuration has been developed to provide strict compliance with API Standard 610, 7th Edition, and Section VIII of the ASME Code by rigorous reading and interpretation of these standards ...
    • Development Of A Magnetic Bearing, API Process Pump With A Canned Motor 

      Hanson, Lloyd; Imlach, Joseph (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
      A new class of pumps has been developed where both end face seals and contacting bearings are eliminated. The objective is to provide a sealless pump with long life bearings meeting the duty requirements of API Standard ...
    • Evaluation Of Coatings For Resistance To Abrasive And Adhesive Wear In Pump Components 

      McCaul, Colin; Kaufold, Roger (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
      Long term pump efficiency and durability are directly related to the ability of materials of construction to resist various forms of wear. The need for resistance to both adhesive and abrasive wear is often greatest in ...
    • Inside The Sealless Pump 

      Veness, J. W.; Steer, C. J.; Rose, S. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
      Sealless pumps are now specified as the preferred type for handling of toxic, hazardous, and environment threatening chemicals. Magnetically driven sealless pumps have emerged as the first choice, due to their simplicity ...
    • Liquified Natural Gas Pump With Hydrostatic Journal Bearings 

      Katayama, Tatsuo; Okada, Akihisa (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
      In view of the inflammability of LNG (liquefied natural gas), submerged type pumps are normally used to protect against leaks. The overhaul interval of an LNG pump, therefore, is subject to the life of its ball bearings, ...
    • Mechanical Seal Chamber Design For Improved Performance
