Development Of A Twin Hybrid Noncontacting Gas Seal And Its Application To Process Pumps
(Texas A&M University. Turbomachinery Laboratories, 1999)
In this paper, an innovative approach of applying gas-lubricated, noncontacting sealing technology to process pumps is presented, in which a novel “twin hybrid” design is incorporated to address the issues of gas seal ...
Component Balance For Centrifugal Pumps - Effects Of Product Design, Balance Machine Tooling, And The Balancing Process On Balancing Repeatability
(Texas A&M University. Turbomachinery Laboratories, 1999)
Balancing of pump rotating components, especially impellers, is common practice. The purpose of this effort was to determine the proper design of pump components and balance arbors, create appropriate procedures, and ...
An End-User’s Guide To Centrifugal Pump Rotordynamics
(Turbomachinery Laboratory, Texas A&M University, 2011)
This tutorial outlines the basics of pump rotordynamics in a form that is intended to be Machinery End User friendly. Key concepts will be defined in understandable terms, and analysis and testing options will be presented ...
Pipeline Vibrations And Pressure Pulsations—Reasons And Solutions
(Turbomachinery Laboratory, Texas A&M University, 2011)
Every pump has some kind of non-continual conveying behavior or effect. Because the conveyed liquids as well as the pipelines and support structures in the connected system are elastic, the conveyed liquid will transport ...

The tutorial outlines the basic concepts and offers some tips on witness testing of API 610 centrifugal pumps and API 611 steam turbines. The section on API 610 pump testing discusses performance, NPSH and mechanical run ...
Wear Reducing Technology Newly Applied To Severe Pumping Services
(Turbomachinery Laboratory, Texas A&M University, 2011)
A U.S. Gulf Coast refinery had experienced accelerated internal wear of FCCU cycle oil pumps, often requiring entire case replacements. Compared to typical industry pump performance, run lengths were shorter, and cost per ...
Upgrading A Set Of Large Cooling Water Pumps With The Aim To Increase Capacity
(Turbomachinery Laboratory, Texas A&M University, 2011)
Mechanical Seals For High-Speed Boiler Feed Pumps In Ultra-Pure Water
(Turbomachinery Laboratory, Texas A&M University, 2012)
Since 2007, the hot-filament Chemical Vapor Deposition (CVD) technology for crystalline diamond thin-film coatings has found its way into the mechanical seal market to combat the problems of dry running, corrosion and ...
