Shiels, Stan T. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Proper pump specification and selection results in the best pump being purchased for the required service. Economic considerations may meant that “best” is not always the most efficient, best hydraulic fit or most expensive. ...
-
Miller, John E. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)A discussion is presented on the physical differences between centrifugal pumps and reciprocating pumps. The disparities are explained in a nonbiased manner and such knowledge should precede an introduction to reciprocating ...
-
Lorenc, Jerome A. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Monitoring the condition of bearings in centrifugal pumps continues to be an important concern to pump users, especially in critical pump installations. Additionally, pump users are interested in simple, easy to use, ...

Heald, Charles C.; Penry, David G. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Pump thermal distortion problems routinely arise in refinery applications where hot fluids must be handled. This is particularly the case when warming up standby pumps. The single stage, double suction configuration, which ...
-
Lebeck, Alan O. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)It is well known that the fluid pressure distribution between the faces of a mechanical seal greatly affects seal performance. In cases where a sealed fluid changes phase from liquid to vapor as it leaks across the seal ...
-
Mowrey, Conrad C. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Centrifugal pumps that fall into a category defined as high head, low flow pumps are discussed. A brief history of these pump types is presented. The principle of operation and performance envelope are addressed. Comparative ...
-
Datta, Amit; Gardner, James F.; Derby, James U.; Casucci, David P. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Metal bellows seals have been steadily gaining wider acceptance in process and general industrial pump applications. This paper discusses design criteria and advantages of metal bellows seals, and attempts to define ...
-
Nikolajsen, Jorgen L.; Gajan, Richard J. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)A new computer program for pump rotor analysis has been developed to improve the accuracy of critical speed, stability, and response calculations for multistaging centrifugal pumps. The program capabilities include: (1) ...
-
Rappold, Walter (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)The multistage variable drive, called MSVD, the latest development of a hydrodynamic mechanical drive system is presented. The special characteristics are high efficiency, excellent reliability, and availability, which are ...
-
Gopalakrishnan, S. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Appropriate specification of minimum flows is important to avert pump reliability problems. A method is presented for the calculation of minimum flow by allowing a satisfactory margin below the onset of flow recirculation ...
-
Karassik, Igor J.; McGuire, J. T. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Every industrial process which underlies our modern civilization involves the transfer of liquids from one level of pressure or static energy to another level, and, as a result, pumps have become an essential part of all ...
-
Monroe, Perry C. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Methods used by the author to level and epoxy grout pump baseplates. The methods used are not the only way pumps can be installed, but if followed, will ensure a 100 percent void free grout job. Execution of the leveling ...
-
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 ...
-
Verhoeven, Jan J. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Operating speeds of multistage pumps tended to increase during the last decade from 4000 to 6000 rpm to 7000 to 10000 rpm, due to new super critical powerplant designs and new conversion processes in the hydrocarbon industry. ...
-
Solutions To Abrasive Wear-Related Rotordynamic Instability Problems On Prudhoe Bay Injection Pumps Valantas, Robert A.; Bolleter, Ulrich (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Prudhoe Bay produced water injection pumps suffered serious vibration problems and high balance piston leakage a few months after initial startup. Even though initial pump orientation at low water rates was satisfactory, ...

Cummings, John M. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)A description is presented from a user’s viewpoint, of a vibration monitoring program using a portable data terminal (PDT) system. A brief description of these systems is given, followed by an explanation of what they can ...

Greutink, Herman A. J. (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Vertical diffuser type pumps, their applications, advantages, disadvantages, multistaging, manufacturing, material selection, construction possibilities, operation, and repair are reviewed. Also discussed are semi-open and ...
