(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)API 682 is the leading document for mechanical seals in petrochemical, chemical, and pipeline services worldwide. It has combined the aspects of seal design, testing, standardization, and applications to provide the users ...
-
(Texas A&M University. Turbomachinery Laboratories, 2002)The first edition of API 682 was the first broad-based standard covering the design and application of mechanical seals in centrifugal and rotary pumps. One of the main goals of this standard was to capture successful field ...

(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)Traditionally, the hydraulic design of impellers has been more of an empirical art than a well-defined engineering science. Because of the empiricism, new designs have been disappointing at times. Discussed here is a “new” ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)The designer of the centrifugal pump impellers requires knowledge of the velocity flow field entering the impeller for several reasons. These include an assurance that a reasonably uniform field exists, that the leading ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)As the usage of sealless pumps increases, so do the demands for journal bearing materials that can operate successfully through the thermal upsets that can take place in these pumps. Material specification literature is ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)The use of variable frequency drives (VFD) in pumping applications with variable-duty requirements provides the user with a variety of benefits, including potentially significant energy savings and improved reliability ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)Under extreme conditions, pumps may be required to withstand severe nozzle loads, which often exceed the API 610 specified values. To meet these requirements, pump mechanical behavior versus nozzle loads must be examined ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)In recent years, cooling requirements for mechanical seals have become a subject of controversial opinions. While the maximum limiting temperatures of mechanical seals are known and specified by seal manufacturers, the ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)Proper use of current analytical and experimental techniques is essential to finding and solving structural resonance problems in pumps. Available techniques vary from the relatively simple to the very complex. Accuracy ...
-
(Texas A&M University. Turbomachinery Laboratories, 1998)For many years, acceptable seal performance was defined as “minimal or no visible leakage.” During the last decade, these definitions have changed immensely as government and industry have combined in a massive effort to ...

-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)In 2010, the Vibration Institute sought to establish a certification for shaft alignment technicians, similar to their certification for vibration technicians and analysts. Various alignment tool vendors and industry ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)The baseplate and nozzle loading criteria in the December 1985 draft version of API610 7th Edition is substantially different from the criteria found in the 6th Edition. The optional heavy duty baseplate criterion has been ...
-
(Texas A&M University. Turbomachinery Laboratories, 2002)API Standard 610, “Centrifugal Pumps for Petroleum, Heavy Duty Chemical and Gas Industry Services,” has been revised from the Eighth Edition to the Ninth Edition and developed into an International Standard, ISO 13709. The ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)API 682, now in its 4th Edition, has made a concerted effort to accurately define and distinguish between different types of seal configurations available under the designation of ‘Arrangement 2’, including 2CW-CW, 2CW-CS, ...

-
(Texas A&M University. Turbomachinery Laboratories, 2003)For the first time, there is an API standard relating to the use of sealless pump technologies [canned motor pump (CMP) and magnetic drive pump (MDP)]. While sealles technology has been well accepted in chemical process ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Tutorial 7: Integrally geared compressors (IGC’s) are common in plant/instrument air service as well as air separation applications, and continue to gain acceptance over a wide range of other applications. An IGC can achieve ...
