Compression packing is one of the oldest and most common seal technologies. A gland along the top packing ring is tightened, and the packing is then compressed onto the stuffing box.
Packings are constructed of relatively soft materials. They are inserted into the pump as cut rings between the rotating member and the body of the pump casing, valve, or other asset. By tightening the gland against the outboard ring, pressure is transmitted to the packing set. This pressure expands the rings radially and creating a seal.
Common Packing Applications & Accessories
Some common applications for packing include:
- Pump packing
- Valve packing
- Packing for other rotating, reciprocating, and static equipment for the process industries and manufacturers.
Many accessories are also available to support the installation, operation, and removal of compression packing.
