Variations of Compression Packing
Successful fluid sealing of valves and pumps cannot be accomplished without the appropriate sealing device. Whether using mechanical seals or compression packing, one must understand the specific needs of the application.
While mechanical seals in general are considered the superior sealing device, they are more expensive and less versatile than compression packing. Compression packing is more versatile due to the vast selection of materials used to make it and the various ways it is constructed. Materials such as vegetable fibers, man-made fibers, metals, graphite, and hybrids are all used to make packing. Construction types include braided, twisted, wrapped (rolled, folded), extruded, laminated, bulk, and die formed.
Construction types of compression packing each have variations within. This article will focus on braided

It’s highly likely that, at some point or another, you have seen braided packing in or out of its “natural environment.” Braided packing looks like rope and is cut into rings that wrap around a rod. While packing used to be available in fairly limited styles, the mechanical packing industry has expanded over time, resulting in braided packing that is available in everything from flexible graphite to fiberglass yarn. Let’s dive into this topic, and discuss the different materials from which braided packing is made in this day and age.
Fiberglass Rope
One of the reasons why fiberglass ropes are favored for braided is that it does not burn. It can be used in continuous temperatures, up to 1,000 degrees Fahrenheit. This makes it perfect for products that are going to exist in high pressure, high-temperature environments. Furthermore, E glass in particular consists of

The FLUSH-GARD™ Sealing System from Garlock is an alternative to traditional packing sets in stock pumps, agitators, and other applications handling solid/liquid mixtures. It extends equipment life by protecting sleeve (non-contact) and packing from media attack, while also providing significant cost savings by reducing flush water consumption by up to 90%, as proven with installation of a flowmeter.
Harmful solids and particulate are contained from entering the stuffing box as the flush water is forced by the FLUSH-GARD™ bushings' unique design - integral tangential multi-porting - toward the pumped media, utilizing the shaft's rotation and centrifugal forces that are created. A small amount is allowed into the stuffing box to lubricate and cool the braided packing.
