Description
Injectable White is based on a blend of mixed PTFE fibres with PTFE solids and a high-temperature grease.
It is pressure injected by hand-operated gun through a non-return valve directly into the gland housing, where two end rings of conventional packing are suitably sited to retain the sealing compound. The gland follower is then adjusted to compress the materials and form a seal.
Typical applications
Centrifugal pumps and rotary mixers that handle cooling water, aqueous solutions, oils or solvents, particularly in processing sectors such as pulp and paper, metallurgical or mineral.
Injectables are sometimes used because they readily conform to worn shafts or irregular shaped housings.
