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, ...

Vetter, Gerhard; Schlucker, Eberhard; Horn, Waldemar; Neis, William E. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)The application of diaphragm pumps for metering and conveying the fluids are continuously expanding because they provide zero-leakage, can run dry, have superior efficiency, offer high reliability, maximize safety and ...

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 ...

Vetter, Gerhard; Seidl, Bernd (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)The safe design of piping installations for reciprocating pumps requires proper knowledge about the pump installation interaction. A compact review shows pump vibration spectra excited by the pumps and methods of numerical ...
-
Vetter, Gerhard; Thiel, Erwin; Stork, Ulrich (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)The working mechanism and life expectancy of automatic pump check valves, which are important for the operational safety of oscillating displacement pumps, are closely examined. A calculation process for the determination ...
-
Vetter, Gerhard (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)The aim of pump development in recent years has been mainly reliability, safety, low maintenance, and the avoidance of dangerous leakages. For years, more and more rigid regulations against pollution and for better safety ...
-
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 ...
