How To Improve Reliability In Centrifugal Pump Systems Through The Automatic Tuneup Of Pumps Within Their Best Operational Condition
(Texas A&M University. Turbomachinery Laboratories, 2008)
Many centrifugal pump reliability problems are closely related to oversizing of pumps, which leads to highly restricted discharge valve operation, and flowrates are far below the best efficiency point (BEP), which are ...
Guidelines For Application Of High Temperature Dual Seals
(Texas A&M University. Turbomachinery Laboratories, 2008)
High temperature services are on of the more challenging applications for mechanical seals. Herein are recommendations and guidelines for selection and application of dual metal bellows seals for use in high temperature ...
Adequacy Of The Flow Loop Control Of Pumps Operating In A Parallel Configuration Whenever Any Of The Pumps Are Tripped
(Texas A&M University. Turbomachinery Laboratories, 2008)
Influence Of Gas Seals On Pump Performance At Low Suction Head Conditions
(Texas A&M University. Turbomachinery Laboratories, 2000)
Pressurized gas seal technology has been applied successfully to many types of equipment, in various processes, and under diverse operating conditions. Using a readily available gas supply, typically nitrogen, the seal is ...
Improving The Reliability And Performance Of A Melt Pump Application In A Petrochemical Plant With Block Style Universal Joints
(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 ...
Nuclear Waste Transfer Pump - Design, Analysis, Testing, And Operation
(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 ...
Developing Fixed-Fee Seal Agreements To Improve Pump Reliability
(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 ...
Mass Customized Design And Manufacturing System Of Advanced Hydraulic Parts
(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 ...
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 ...
Bone-Dry Running Tests Utilizing Diamond Like Carbon Coated Silicon Carbide Bearings And Polymer Lubricating Strips In An ANSI Magnetic Drive Pump
(Texas A&M University. Turbomachinery Laboratories, 1997)
Dry run failures in sealless pumps continue to be of major concern to users and, in some cases, have precluded the purchase of these types of pumps. Users are demanding robust pump designs that are more tolerant of dry ...
