Urquhart, C. Daniel; Wordley, Mark (Texas A&M University. Turbomachinery Laboratories, 2000)There are very basic differences between the centrifugal and positive displacement pump. This paper discusses some of these aspects. It is not intended to be highly theoretical, but deals with the practical differences ...

Miyasaka, Matsuho; Takayama, Hirokazu; Amaya, Kenji; Aoki, Shigeru (Texas A&M University. Turbomachinery Laboratories, 2000)A computer aided corrosion-analysis-system to which boundary element method (BEM) is applied has been developed, and is utilized for diagnostic galvanic corrosion and designing cathodic protection of seawater and brine ...
-
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 ...

Pacella, John; Hanas, Peter (Texas A&M University. Turbomachinery Laboratories, 2000)This paper describes a unique pumping concept based on a noncontact mechanism operating solely using the principles of boundary layer and viscous drag. The first section focuses on the pumping technology itself, describing ...

Bross, Stephan; Amann, Peter; Baumgarten, Sven; Muller, Thomas (Texas A&M University. Turbomachinery Laboratories, 2000)In the present paper, the adaptation of existing cooling water pumps to extreme part load condition by cutting down the impeller in the meridional plane is described. The influence of different impeller shapes on the head ...

Etsion, lzhak (Texas A&M University. Turbomachinery Laboratories, 2000)Significant improvement in load capacity, wear resistance, friction coefficient, etc., of mechanical seals can be obtained by forming regular microsurface structure in the form of micropores on their surfaces. A feasibility ...
-
Cropper, Michael S.; Schmid, Richard K.; Mohanty, Mahesh (Texas A&M University. Turbomachinery Laboratories, 2000)In hydrocarbon processing and oil and gas industries, many pumps are required to transport fluids containing some level of abrasive solids. If not properly designed and equipped with wear resisting materials, the pump ...
-
Turley, Roger S.; Dickman, David L.; Parker, Joseph C.; Rich, Robert R. (Texas A&M University. Turbomachinery Laboratories, 2000)Pressurized gas seal technology has been applied successfully to many types of equipment, in various processes, and under diverse operating conditions. Using a readily available gas supply, typically nitrogen, the seal is ...
-
Investigations Into The Contamination Of Lubricating Oil In Rolling Element Pump Bearing Assemblies Bradshaw, Simon (Texas A&M University. Turbomachinery Laboratories, 2000)The use of rolling element bearings in pumps is standard practice. Of the many factors that affect their long-term performance, contamination in the bearing lubricating oil plays a major part. Of particular concern are ...
-
Demmel, Martin; Tornqvist, Per Eric (Texas A&M University. Turbomachinery Laboratories, 2000)The pulp and paper industry as well as all other industry branches are subject to continuous, ongoing development. Mechanical seals have already replaced stuffing-box packings in virtually all pulp and paper factories in ...

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 ...
-
Zaher, M. A. (Texas A&M University. Turbomachinery Laboratories, 2000)During the past three decades, there have been notable advances in the design of pumps. In a number of projects, the designers of process plants had, during optimization of their layouts, established a requirement for pumps ...
-
Jones, Robert M. (Texas A&M University. Turbomachinery Laboratories, 2000)It has been said that if one has perfect information, then one can make perfect decision. In the daily operation of a production facility, many decisions are made each day concerning the mechanical condition of production ...
-
Morales Casanova, César A. (Texas A&M University. Turbomachinery Laboratories, 2000)A modification of seven 560 hp vertical-turbine pumps was carried out with outstanding results to improve their actual capacity. The installation was limited to 64% of its rated capacity, which was never reached, and the ...

Wallace, Neil M.; Redpath, David; Netzel, James P. (Texas A&M University. Turbomachinery Laboratories, 2000)Pump components such as seals and couplings affect the reliability and operating costs of pumping equipment directly. By reference to basic principles, those effects will be quantified and compared with the overall running ...
