The Vulcan Seals Type 11J is a resilient, rubber diaphragm mounted parallel spring seal design with self-adjusting head to accommodate minor shaft misalignment and run-out.

The seal drive is provided by the diaphragm bellows tightly gripping the shaft and providing positive drive to the seal head and sealing face. The Vulcan Seals diaphragm seal designs are bi-directional "pusher" seals that minimise shaft fretting as the spring is constantly providing energising force to the shaft contact point and sealing face.

Supplied with a Vulcan Seals Type 31 'O'-ring stationary with anti-rotation provision suitable for common metric and imperial USA market regular length seal chambers.
