The Effects Of Valve Dynamics On Reciprocating Pump Reliability
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Compared to leading edge technologies such as high speed turbomachinery, reciprocating pumps may appear to be a simple technology: A reciprocating plunger causes liquid to be drawn from a low pressure manifold through the ...
Design And Testing Of Dual Seal Series Arrangements For Pressurized Barrier Fluid
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Dual mechanical seals are operated on pressurized barrier fluid systems when the pump product properties do not support reliable single seal operation. This provides added protection against environmental release of the ...
Diaphragm Development Trends For Safe Leak Free Reciprocating Process Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The application of diaphragm pumps for metering and conveying the fluids are continuously expanding because they provide zero-leakage, can run dry, have superior efficiency, offer high reliability, maximize safety and ...
Dual Gas Sealing Technology For Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Dual gas seals are gaining acceptance by industrial users as a product that offers advantages over conventional liquid lubricated seals. These advantages are measured in terms of controlling emissions, minimizing product ...
Dry Running Bellows Type Tandem Seals For VOC Services
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Dry running bellows seal technology, where the secondary (outer) seal operates in a dry condition, was originally developed in the UK and Europe for protection against primary seal failure. Over the past three years, it ...
Dry Running Tests Utilizing Silicon Carbide Bearings And Polymer Lubricating Strips With Conductive And Nonconductive Containment Shells In An ANSI Magnetic Drive Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
As users continue to turn to sealless pumps to solve their leakage (emission) problems they are demanding robust designs that are more tolerant of system upsets and have the ability to survive short periods of dry running. ...
Understand Progressing Cavity Pumps Characteristics And A Void Abrasive Wear
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Progressing cavity pumps develop their pumping action by the meshing of the external threads of the elastomer stator and the internal threads of the metallic rotor. The special geometry, as characterized by the different ...
The Road To Reliable Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Centrifugal Pumps Inspection And Testing
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The general requirements for inspection and testing of centrifugal pumps are presented. The successful completion of inspection and testing verifies pump design and specification compliance prior to release of pump for ...
Shaft Alignment
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Proper alignment of rotating equipment has long been recognized as a prerequisite to safe, reliable operation. Achieving proper alignment, however, involves much more than merely adjusting the machines so that the shafts ...
