Pack Seal Pdf For Free

PRESSURE / PLASTICITY Most metal seals create tight seals through a concept known as plastic deformation. This is accomplished by utilizing a so outer coating, such as PTFE, gold or silver, and then applying a specific amount of force to deform the outer layer into the mating hardware as shown.

Our standard range includes; GRAPHITE, PTFE and GREASY. These materials have been specifically chosen for their excellent wear resistance as well as fluid sealing properties. They can also provide good chemical resistance and tolerate poor mechanical conditions, with off-centre shafts or worn bearings.

Provide secondary seals to prevent leakage past the gland. Or along the shaft.

Gland packings consist of a braided or twisted material, such as graphite, PTFE or aramid fibres, that are placed around a shaft or valve stem. The packing material is compressed against the shaft or stem by a gland, which is a mechanical seal that is tightened to create a secure, leak-free seal.

Packing seals rely on a rope-like packing that wraps around the shaft of a pump to fill the voids and prevent fluid from escaping. Mechanical seals are often preferred when leakage is unacceptable, such as applications involving hazardous materials.

A mechanical seal consists of 2 principle components. One component is stationary and the other rotates against it to achieve a seal (Figure 2). There are many types of mechanical seal, ranging from simple single spring designs to considerably more complex cartridge seal types.
