    • Cavitation In High Energy Pumps - Detection And Assessment Of Damage Potential 
      Sloteman, Donald P. (Texas A&M University. Turbomachinery Laboratories, 2007)
      Cavitation In centrifugal pumps is one of the fundamental factors that affect performance, operability, reliability, and life. Every major manufacturer of engineered, high-energy, centrifugal pumps has addressed these ...
    • Control Of Backflow At The Inlets Of Centrifugal Pumps And Inducers 
      Sloteman, Donald P.; Cooper, Paul; Dussord, Jules L. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
      Cavitation surge or the interaction of backflow from the inlet of a centrifugal pump or inducer at low flow and low NPSH can be eliminated by the use of backflow recirculator. Experimental results from four pumps demonstrate ...
    • Demonstration Of Cavitation Life Extension For Suction-Stage Impellers In High Energy Pumps 
      Sloteman, Donald P.; Robertson, Douglas A.; Margolin, Leo (Texas A&M University. Turbomachinery Laboratories, 2004)
      Cavitation occurring in high-energy pump impellers often results in material erosion and system instabilities. Excessive erosion rates compromise life and increase ownership costs through higher maintenance and reduced ...
    • Developing Sealless Integral Motor Pumps Using Axial Field, Permanent Magnet, Disk Motors 
      Sloteman, Donald P.; Piercey, Mark (Texas A&M University. Turbomachinery Laboratories, 2000)
      Problems with mechanical shaft seals account for the majority of pump maintenance costs. When pumping critical or hazardous fluids, users can resort to sophisticated mechanical shaft sealing systems, complicated buffered ...
    • Elimination Of Cavitation-Related Instabilities And Damage In High-Energy Pump Impellers 
      Cooper, Paul; Sloteman, Donald P.; Graf, Edward; Vlaming, Dirk J. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
      The suction-stage impeller of a large crude oil pipeline pump was designed by combining quasi-three dimensional flow analysis with current theories to generate an impeller geometry, which was evaluated in a half-size model ...
    • Experimental Evaluation Of High Energy Pump Improvements Including Effects Of Upstream Piping 
      Sloteman, Donald P.; Wotring, Timothy L.; March, Patrick; McBee, Dan; Moody, Larry (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
      The suction-impeller (single-suction) of a 33,500hp, four-stage barrel pump used in boiler feed service at a fossil fuel steam plant experienced operating life ranging from 6.0 to 19 months. Cavitation erosion on the suction ...
