The Vulcan Seals Type 1645BS is a robust, 'O'-ring mounted "pusher" seal design with multiple springs and a monolithic sealing face intended for step-shaft installations. The drive from the shaft and the seal working length is by set screws tightened using the supplied Allen key.

The set screws provide bi-directional rotation capability. The multi-springs and step-shaft layout provide even closing forces and hydraulic balancing giving improved pV capability and higher sealing performance. The robust design and multi-spring arrangement provide optimised performance in challenging industrial applications when compared to single-spring seal designs.

The Vulcan Seals Type 1645BS complete seal is supplied with the Vulcan Seals Type 25 clamped in place stationary. The Vulcan Seals Type 1645BS rotary is compatible with a wide range of Vulcan Seals stationary types.
