Pump and valve packings are essential sealing components designed for dynamic environments such as valves, expansion joints, and various pump types including rotary, centrifugal, and reciprocating models.
These packings consist of soft, flexible yarns, often braided to enhance durability and adaptability. Performance can be further optimised with additives like lubricants or wire reinforcements tailored to specific operational needs.
Supplied in set lengths, the packings are cut into rings that fit snugly between the rotating shaft and the pump or valve housing. Tightening the gland follower compresses the packing, causing it to expand radially and create a tight seal that effectively prevents leakage.
Each type of pump and valve packing offers distinct characteristics such as temperature tolerance and chemical resistance. Comprehensive technical data, including WRc certifications and food contact approvals, are available for all products. A detailed comparison table is provided to assist in selecting the ideal packing for your application.
