    • Influence Of Impeller Suction Specific Speed On Vibration Performance 
      Bradshaw, Simon; Cowan, David; Liebner, Thomas (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
      The most commonly used hard limitation for pump suction specific speed is 11,000 (US units). This hard limit grew out of the recommendations from a 1982 reliability study by J.L. Hallam (Hallam 1982). Concomitant testing ...
    • The Influence of Impeller Wear Ring Geometry on Suction Performance 
      Liebner, Thomas; Cowan, David; Bradshaw, Simon (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      Wear rings are a necessary feature of an enclosed centrifugal impeller design. The purpose of the wear ring is to limit the leakage of fluid from the high pressure zone at the impeller outlet to the low pressure region at ...
