Common questions
How does compression packing work?
Compression packing works by placing flexible packing rings around a pump shaft inside the stuffing box. When compressed, the packing forms a seal that controls leakage while allowing shaft movement. John Crane compression packing materials are designed to provide effective sealing, managing friction and supporting reliable pump operation across demanding industrial applications.
What is pump packing?
Pump packing is a sealing solution used to control leakage around rotating pump shafts. It consists of deformable packing materials that create a seal when compressed inside the stuffing box. John Crane’s pump packing solutions are engineered to balance leakage control, shaft protection and reliable performance across a range of operating conditions.
How to replace packing in a pump?
Replacing pump packing involves removing old packing rings, inspecting the shaft and stuffing box, and installing new rings correctly sized and staggered. John Crane recommends following proper installation procedures to ensure reliable sealing.
What is injection packing?
Injectable packing is a sealing material that can be injected directly into the stuffing box while equipment remains in operation. It is used to manage leakage, improve sealing performance and support temporary or emergency sealing without shutting down the pump.
