A Comparison Of The Application Of Centrifugal And Positive Displacement Pumps
(Texas A&M University. Turbomachinery Laboratories, 2000)
There are very basic differences between the centrifugal and positive displacement pump. This paper discusses some of these aspects. It is not intended to be highly theoretical, but deals with the practical differences ...
Discussion Group T2 (Jointly with P6) On Monitoring Vibration and Other Critical Machine Conditions
(Texas A&M University. Turbomachinery Laboratories, 2011)
Discussion Group P4 (Jointly with T8) On Couplings and Alignment
(Texas A&M University. Turbomachinery Laboratories, 2011)
Using engineered composite materials in sealless magnetic drive pumps to eliminate eddy currents and improve reliability
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Background - Pump application: This case study is based on an application supplied into a Polysilicon production facility. The purpose of the application is to pump Trichlorosilane (TCS) liquid into the production process ...
Thermal Load Effect on Vibration on a Reactor Feed Water Pump (FWP)

The Influence of Impeller Wear Ring Geometry on Suction Performance
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Wear rings are a necessary feature of an enclosed centrifugal impeller design. The purpose of the wear ring is to limit the leakage of fluid from the high pressure zone at the impeller outlet to the low pressure region at ...
Eliminating Damage of Retaining Rings by Using Redesigned "Profiled" Keys
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Retaining rings are used to locate pump impellers axially on the shafts of high speed, high pressure Siemens Delaval boiler feed pumps. Upon repairing and refurbishing the inner barrels, the retaining rings were found to ...
Barrier And Buffer Fluid Selection And Considerations For Mechanical Seals
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The increased use of pressurized and non-pressurized dual mechanical seals has driven more installations to require the use of barrier and buffer fluids. While some end users have viewed the selection of barrier fluids as ...
High Vibration Analysis of Eddy Current Drum Coupled Motor to a Vertical Centrifugal Pump : Solution Based on EMA, ODS and FEA
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The 35-year old pump station moves up to 43 MGD of raw wastewater to the city’s treatment facility via two 1,500-hp high-capacity pumps for wet weather flows. After the motors were refurbished in 2011, excessive motor ...
Pump Performance And Energy Efficiency Improvement Through Pump Refurbishment And Internal Coatings Of Horizontal Split Case Pumps
(Texas A&M University. Turbomachinery Laboratories, 2008)
