International Pump Users Symposium (18th : 2001) (Texas A&M University. Turbomachinery Laboratories, 2001)
-
Petersen, John E. (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 ...
-
Case, Greg; Marscher, William D. (Texas A&M University. Turbomachinery Laboratories, 2001)This tutorial discusses hydraulic and mechanical issues that are of primary importance in centrifugal pumps and their systems, and how pump users can best address these issues. It is shown how to concise and orderly review ...
-
Fontaine, Marc L.; Hajlich, Eileen (Texas A&M University. Turbomachinery Laboratories, 2001)Long-term contractual agreements between a mechanical seal supplier and an end-user have proven to be a very effective method for improving equipment reliability. Successful agreements change the focus of a user/supplier ...

Stavale, Anthony E.; Lorenc, Jerome A.; Sabini, Eugene P. (Texas A&M University. Turbomachinery Laboratories, 2001)In today’s global economy, process plants are under constant pressure to reduce costs. Users can no longer afford their attempts to make pumps bulletproof by upgrading component specifications. The development of a smart ...

Morales Casanova, César A. (Texas A&M University. Turbomachinery Laboratories, 2001)Four 580 HP cooling tower feed pumps were upgraded by retrofitting improved bowl assemblies with enclosed stainless-steel impellers. Pumps exhibited capacity limitation up to 50% of rated and cavitation damage in original ...
-
Hudson, Andrew; McGinnity, Matthew A.; Amin, Parthiv R. (Texas A&M University. Turbomachinery Laboratories, 2001)A major chemical company has implemented a cost reduction and performance enhancement via universal joints on a melt pump application. The melt pump is used to push molten polyethylene through a die to produce pellets. The ...

Kato, Hiroyki; Goto, Akira; Takayama, Hirokazu; Saito, Sumio; Enomoto, Takashi; Nabe, Shiro (Texas A&M University. Turbomachinery Laboratories, 2001)This paper describes a production system for hydraulic parts. The system allows the rapid development and fabrication of hydraulic parts for custom-made pumps through the integration of innovative means and the positive ...
-
Guardiani, Richard F.; Hauck, F. Marshall; Riesenweber, Stephen D. (Texas A&M University. Turbomachinery Laboratories, 2001)There was a time when people worked on radiologically contaminated equipment with a low level of protection, when equipment leakage was considered unavoidable, and when contaminated equipment was disposed of with little ...
-
Dupont, Philippe (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 ...
-
Schmidthals, Cord; Greitzke, Stephan F. (Texas A&M University. Turbomachinery Laboratories, 2001)It is well known from long-term experience that life-cycle costs of a pump are determined by the consequential cost associated with pump failures. The failure of a pump, often originating from system-related nonpermissible ...
-
McGuire, James T. (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 ...
-
Cooper, Paul (Texas A&M University. Turbomachinery Laboratories, 2001)
-
Netzel, James P.; Voigt, Joachim (Texas A&M University. Turbomachinery Laboratories, 2001)Advancements in the science of sealing technology have had a dramatic effect in increasing equipment reliability and reducing the cost of equipment ownership. One such area of success has been the pumping cryogenic fluids ...
-
Habets, G.L.G.M.; Smalley, Anthony J. (Texas A&M University. Turbomachinery Laboratories, 2001)This paper presents the rotordynamic characteristics of a vertical submerged hydraulic turbine generator obtained during design, manufacturing, shop testing, and site testing. The hydraulic turbine represents a new design ...
-
Wilcox, Ed (Texas A&M University. Turbomachinery Laboratories, 2001)Modifications to a high-pressure, high-temperature barrel pump to increase seal reliability and throughout are discussed. The pump is in unspared hydrodewaxer (HDW) feed service. The original seal design included nonpressurized ...
-
Patel, Vinod P.; Coppins, Donald G. (Texas A&M University. Turbomachinery Laboratories, 2001)Lube oil systems are utilized in rotating process equipment to lubricate and cool hydrodynamic bearings. These systems are essential to the life and maintenance-free operation of the process equipment. Dependable performance ...
