(Texas A&M University. Turbomachinery Laboratories, 1998)A case history is presented pertaining to five (four operating and one spare), 150 hp sealless pumps operating in parallel in a closed loop-65° chilled liquid system. The pumping system is designed to use a liquid refrigerant ...
-
(Texas A&M University. Turbomachinery Laboratories, 1997)Chemical and process plants usually contain numerous valves and pumps in a complex network of pipe runs. Plant design and pump selection are usually based on steady state design conditions. However, the opening or closing ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Test results for an ASME Power Test Code 10 (PTC) Type 1 test of a 4,500 psia (310 Bara) discharge pressure gas lift centrifugal compressor outfitted with dynamic pressure-balanced seals at the impeller eyes; shaft interstage ...
-
(Texas A&M University. Turbomachinery Laboratories, 2003)Monte Carlo analysis is a powerful tool for modeling the reliability of systems. Proper application of this tool requires an understanding of its underlying principles. In this paper, Monte Carlo analysis is explained at ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)A new project to increase the oil produced at Khurais, Saudi Arabia, was the focus of a study to determine the optimal pipeline size and pump combination for a 90.4 mile (145.5 km) long, treated-seawater transfer line ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)It is widely acknowledged that sealless magnetic drive pumps give total containment of the pumped process liquid, which in an industry where there are ever tightening environmental constraints on plant operation and ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)Pumps operated with variable and higher speed electric motors provide numerous benefits such as greater range of flow and head, higher head from a single stage, valve elimination, and energy saving. To achieve these benefits, ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Pump piping systems typically have small diameter branch connections that can develop vibration related fatigue failures due to mechanical excitation. Many installations do not take time to design small diameter piping to ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)This is a mechanical seal upgrade case study about applying advanced upstream pumping technology instead ofconventional tandem seal arrangements with external flushing in high corrosive fluid pump seal applications in order ...
-
(Texas A&M University. Turbomachinery Laboratories, 1996)Data are being used to determine business decisions in this day of competitive business. In years past, many business decisions have been made without the data to support them. Today, with the use of new computer programs, ...
-
(Turbomachinery Laboratory, Texas A&M University, 2010)Wear erosion needs special attention in pump design as it can lead to severe damage of the pump and restrict its lifetime significantly. It therefore determines to a large extent the selection of a pump. During the design ...

-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)At a facility with four quintuplex pumps, pulsation dampeners were being used to control pulsations in the discharge line. However, the initial dampeners were both undersized and undercharged for the application. As a ...
-
(Texas A&M University. Turbomachinery Laboratories, 2002)Pump reliability problems are responsible for a large amount of the maintenance budget and lost-opportunity cost at chemical plants, refineries, and many electric utilities. This tutorial outlines the typical reasons for ...
