Gallagher is regularly a top 10 Parker distributor, stocking standard parts in its King of Prussia, PA and East Longmeadow, MA branches. The Gallagher engineering department also works with Parker engineers to create custom sealing solutions for our customers.
Parker provides a wide range of specialty elastomers to accommodate the various critical sealing challenges presented by the life sciences industry. Selecting a suitable material is critical to patient health. For this reason, the FDA provides a standard (21 CFR177.2600) defining allowable rubber compound ingredients and extractibles based on toxicity and carcinogenicity.
Thermoseal Inc., an independent Klinger Company, is a leading manufacturer and distributor of fluid sealing materials and fluid control products. KLINGER is a world-leading developer and manufacturer of fluid sealing and fluid control products founded in 1886 by Austrian engineer, Richard Klinger.
Thermoseal’s focus has always been on technical excellence, innovation, and dedication to the customer and their needs. Thermoseal’s Engineering Services, working collaboratively with the Gallagher Engineering Department, is ready to examine and evaluate the application environment in which a gasket will be used, and their fully equipped test lab can provide insight into the performance of a joint.
Gallagher Fluid Seals is a Garlock master distributor. At our facility in East Longmeadow, Massachusetts, we stock a variety of Garlock packing materials in a number of sizes.
We can provide our customers full spools of packing material, or customized packing sets cut to size and engineered specifically for their application.
The Garlock compression packing facility is committed to supplying the highest quality engineered products to industries throughout the world. It is designed to give the user the greatest return on initial investment in terms of leakage control, service life, and dependable, cost-effective product.
The facility also houses the Garlock textile division, where they continue to research and develop new fiber blends to bring customers a wide array of packings with optimum performance characteristics.
Over the past few weeks, we’ve been discussing the basics of PTFE rotary seals. In today’s entry, we’ll take a look at PTFE radial lip seal design principles.
PTFE radial lip seals generally incorporate a uniformly thin element cross section, made to compensate for the high flexural modulus of PTFE, especially in cases of severe shaft run-out. The thin sections also minimize thermal expansion and compressive “creep” and their effects on maintaining a controlled contact pattern on the shaft surface.
Most PTFE seal constructions have the “body” portion of the element clamped between the two metal cases. To maintain proper retention pressure on the element, a thin element keeps compression set and “creep” at a minimum.
ThorPlas-Blue lifetime lubricated bearings provide improved reliability to users by extending equipment operating life and increasing the Mean Time Between Failures (MTBF) across a wide spectrum of industrial applications.
Developed as a maintenance-free solution to replace greased bronze bearings, the proprietary engineered thermoplastic bearing is capable of dynamic operating pressures up to 45 MPa (6527 psi) and can easily be back fit into virtually all applications where greased bronze is currently installed. Higher pressures may be possible with Thordon Engineering review.
ThorPlas-Blue grease-free bearings help reduce maintenance costs and noise levels, have equal or better operating performance over metal bearings, and are available in rod and sheet forms. ThorPlas-Blue not only has a lower density and thus less weight in comparison to metal bearings but it is also self-lubricating which means no grease or oil while eliminating bearing corrosion concerns. A stainless steel or non-corrosive mating surface should be used with ThorPlas-Blue.
The importance of gaskets to the overall health of your machinery and production is often overlooked. While gaskets represent just a fraction of the cost of the machines or systems in which they are installed, the consequences of a failure can range from nuisance leaks to catastrophic failure of a machine or process.
“Damage, downtime, lost production, along with non-compliance penalties, plus the potential for litigation and damage to the company’s reputation, make the cost of gasket failure incalculable,” Jim Drago, P.E., of Garlock Sealing Technologies wrote in a 2008 article on the subject.
