Welded metal bellows seals continue to have success as a core sealing technology and have gained popularity recently in new innovative sealing technologies such as high-temperature non-contacting gas...
To eliminate leakage, mechanical seals are the method of choice in sealing most pumps in ethanol plants. However, eliminating process leakage in rotating equipment does present many unique challenges...
In today's global environment, the "one size fits all" approach is used for so many products that we expect it to apply to just about everything. In the mechanical seal industry, one problem with that...
Two imperatives for many of today's industrial plants are to reduce the cost of operations through the enhancement of rotating equipment reliability and enhanced energy efficiency of pumping systems....
This month's Sealing Sense was contributed by FSA Members Marty Rogin and Jim Richter The March 2009 Sealing Sense concluded that pipe strain can cause failure of the packing or mechanical seal since...
Pumps and Systems, May 2009 Find out why level controls can fail in municipal wastewater treatment plants and similar systems and what technologies are available to combat failure. Leaving the...
Shaft misalignment is one of the most common causes of premature mechanical seal failure. Higher leak rates typify these failures. Rapid failures can occur in high pressure and speed applications....
Q. How Will the P3-A Equipment Standards Affect You? A. The pharmaceutical industry has frequently cited 3-A sanitary standards (used primarily in dairy and other food processing) when specifying...
Sulfur leakage, causing housekeeping and environmental issues in a refinery, was stopped with an innovative seal configuration. No other industry has come under such intense scrutiny as the oil...
The use of gas lubricated mechanical seals in pumps has increased for a variety of reasons. This two part article will address the principles of gas seals, some basic application questions, what to...
Last month's Sealing Sense provided an overview of pump gas seal benefits and general design issues. This article will discuss some application conditions that must be considered when applying gas...
The purpose of a mechanical seal is to prevent leakage but all seals leak to some controlled degree. However, it is important to note that this minimal leakage can be so restricted that specific...
A section of the plant has been shut down because of a temporary change in product mix. New pumps have been installed in a plant addition that will not go on line for some time. In either case,...
