Sealing Solutions: The Future of the Mechanical Seals Market
Frost & Sullivan estimates the total North American mechanical seals market revenues at $992.4.0 million in 2008. Figure 1 shows the revenue trend for the North American mechanical seals market...
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...
Over the years, the FSA Gasket Division has explored many specific sealing and gasketing issues in Sealing Sense. Regardless of all the insights provided, chances are that users of gaskets will be...
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...
What is the Energy Footprint of Sealing Systems?
The term carbon footprint has become synonymous with greenhouse gas (GHG) emissions and climate change. Carbon footprint commonly refers to the volume of greenhouse gases, the most prominent of which...
What is the impact of reliability on the sealing system energy footprint from pump shut down, repair and re-commisioning?
Last of Four PartsThis is the last of a four-part “Sealing Sense” series that has provided guidance on the best practices to minimize the size of the sealing system energy footprint. The first...
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,...
Because of the unique problems experienced with highly viscous fluids that can crystallize to form abrasive particles, as well as those with adhesive tendencies, an alternative to face seals is often...
Such a question often comes up when it is time to recondition a mechanical seal: We use several different brands of mechanical seals in my plant. When a pump is taken out of service, we usually send...
