Compression packing

Control of fluid loss is essential for successful operation of any mechanical equipment. Various techniques of sealing is applied to restrict fluid/gas loss. The oldest and still common method of sealing is compression packing. These packings are made from relatively soft plaint materials. This packing is then cut and performed into number of rings to fit in the annular space (stuffing box). By tightening the gland follower against the top or board, pressure is transmitted, thus expanding packing rings radially to achieve effective seal.

 

Packing applications are found in process industries such as petro chemical, pharmaceuticals, pulp & paper, chemical, steel mills, service industries, utilities, marine, water, sewage, food and fossil and nuclear power plants. Packings can seal all types of fluids including water, steam, acids, solvents, gases, oil, gasoline, numerous chemicals over a broad range of temperature and pressure conditions. Packings can be used in rotary, centrifugal/reciprocating pumps, mixers, agitators, dryers, valves, expansion joints, soot blowers and many other types of mechanical equipments
