Designing An Ultra-Low Specific Speed Centrifugal Pump
(Texas A&M University. Turbomachinery Laboratories, 2005)
Traditional commercial centrifugal pump designs have specific speeds (Ns) greater than 500 because low values of Ns are usually associated with low efficiency, pulsation, and a drooping head characteristic. In this instance, ...

(Texas A&M University. Turbomachinery Laboratories, 2005)
Use Of Inducers In Liquified Petroleum Gas And Condensate Service For Better Performance
(Texas A&M University. Turbomachinery Laboratories, 2005)
The inducer is a very small booster pump, lifting the suction pressure to a sufficient level for the main conventional impeller. By adding the inducer to high speed centrifugal pumps, NPSHr can be reduced to a great extent. ...

Dry Gas Sealing Systems For Oil Sands Pumping Applications
(Texas A&M University. Turbomachinery Laboratories, 2005)
Harmonic Free Magnetic (FCMA) Soft Starters For Large Capacity High Voltage Induction And Synchronous Motors Driving Pumps And Compressors
(Texas A&M University. Turbomachinery Laboratories, 2005)
Most of the water supply schemes use electrical power in large quantities. As such, optimization is needed for reducing life cycle cost of the entire establishment in terms of capital cost, minimum downtime, and maximum ...
Improvements In Bearing Life Using New Sealing Technology
(Texas A&M University. Turbomachinery Laboratories, 2005)
As many as 91 percent of all rolling element bearings fail to achieve their calculated theoretical lifetimes. One of the primary reasons for this failure is contamination of the lubricants. Past practice for protecting ...
A New Concept In Mechanical Seal Cooling - The Integral Heat Sink
(Texas A&M University. Turbomachinery Laboratories, 2005)
Thermally induced failures have long since plagued mechanical seal users. Over the years these failures have led to the development of different flush plan and seal design features that are used to increase heat transfer ...
Practical Design Against Pump Pulsations
(Texas A&M University. Turbomachinery Laboratories, 2005)
One of the foremost concerns facing pump users today is that of pulsation problems in their piping systems and manifolds. In cases where a fluid excitation is coincident with both an acoustic resonance and a mechanical ...
Material Selection For Mechanical Seals
(Texas A&M University. Turbomachinery Laboratories, 2005)
Mechanical seals are used throughout industry to minimize or eliminate leakage in centrifugal pumps, mixers, and other rotating equipment. The ability of a mechanical seal to meet its performance objectives depends upon a ...
