Pump Rerates - When And How
(Texas A&M University. Turbomachinery Laboratories, 2001)
During the life of a plant, there often arises a need to change a pump’s rating to match a new plant operating condition or raise the mean time between repair (MTBR) of an unreliable pump. In these cases, rerating the pump ...
Best Practices In Selecting And Applying Positive Displacement Pumps
(Texas A&M University. Turbomachinery Laboratories, 2001)
Selecting a positive displacement pump is many times a confusing process. Unlike centrifugal pumps were pumping technology is familiar, positive displacement pumps operate differently than centrifugal and there is a wide ...
Pumps - 2000 And Beyond
(Texas A&M University. Turbomachinery Laboratories, 2001)
New Development In Centrifugal Pumps For Optimum Cavitation Performance
(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 ...
Numerical Prediction Of Cavitation In Pumps
(Texas A&M University. Turbomachinery Laboratories, 2001)
With the increase in power per unit of volume for modern pumps, driven by manufacturing costs reduction, cavitation becomes more and more the main limiting factor in pump design. The classical one-dimensional design rules ...
Temperature Measurement At Low Flow On Typical ANSI Chemical Process Pumps
(Texas A&M University. Turbomachinery Laboratories, 2000)
Chemical process pumps can be required to handle highly temperature sensitive liquids. Improper operation of such a centrifugal pump can lead to potentially dangerous liquid temperatures within the pump casing. Determination ...
Rolling Element Bearing Status Using Frequency Analysis
(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 ...
Justifying The Reinstallation And Upgrading Of Problem ANSI Pumps At An Operating Chemical Plant
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Many facilities do not obtain the expected life out of ANSI and other centrifugal pumps, seals, and bearings that need to be obtained to be competitive in today’s market place. The analysis of this situation leads to two ...
Experimental Investigations In Respect To The Relevance Of Suction Specific Speed For The Performance And Reliability Of Centrifugal Pumps
(Texas A&M University. Turbomachinery Laboratories, 1996)
Recently, several recommendations have been proclaimed concerning limitations of the maximums suction specific speeds (n85) of centrifugal pumps. These recommendations result from statistical evaluations of pump failures ...
Modern Manufacturing Of Advanced Impeller And Diffuser Vane Profiles
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Both fluid dynamics and manufacturing technology have seen rapid progress over the last few years. Vane profiles need no longer be developed in cavitation demonstration experiments, but can be optimized by computerized ...
