    • Abrasive Wear In Pumps - A Tribometric Approach To Improve Pump Life 
      Vetter, Gerhard; KieBling, Ralph; Wirth, Wolfgang (Texas A&M University. Turbomachinery Laboratories, 1996)
      The reduction of abrasive wear and extension of the endurance of pumps requires a system analysis. Various pump types demonstrate different tribological systems under abrasive wear, which are basically dominated by sliding, ...
    • Multiphase Pumping With Twin-Screw Pumps - Understand And Model Hydrodynamics And Hydroabrasive Wear 
      Vetter, Gerhard; Wirth, Wolfgang; Korner, Heiko; Pregler, Sabine (Texas A&M University. Turbomachinery Laboratories, 2000)
      Crude oil and gas production can be enhanced by multiphase pumping from the well subsea to far distant production platforms. The twin-screw pump has proven quite suitable for this application. The positive displacement ...
    • Understand Progressing Cavity Pumps Characteristics And A Void Abrasive Wear 
      Vetter, Gerhard; Wirth, Wolfgang (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
      Progressing cavity pumps develop their pumping action by the meshing of the external threads of the elastomer stator and the internal threads of the metallic rotor. The special geometry, as characterized by the different ...
