Vulcan Seals Type 1645B

AESSEAL® - Type N-M06
John Crane® - Type 9BT

The Vulcan Seals Type 1645B is a robust, PTFE wedge-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 are 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 1645B complete seal is supplied with the Vulcan Seals Type 25 clamped in place stationary. The Vulcan Seals Type 1645B rotary is compatible with a wide range of Vulcan Seals stationary types.

Why Choose the Vulcan Seals Type 1645B?

  • Step shaft design allows hydraulic balancing to be incorporated allowing high shaft speeds, higher pressures, and longer run time to be achieved compared to non-balanced seal designs.
  • Highly effective robust design that is commonly used in chemical and petrochemical duties.
  • PTFE wedge secondary seal, VCT1 carbon primary seal face, and Hastelloy-C276® springs ensure compatibility with a wide range of industrial medias.
  • The design features a setting line to aid installation at the correct compressed length.
  • Suitable for medium and heavy-purpose applications with imperial shaft sizes.
  • Vulcan Seals Type 1645B has a narrow radial profile to suit the American ANSI B73-1974 centrifugal pump dimensions standard.
  • Seal face dimensions ensure compatibility with a wide range of Vulcan Seals can stationary ranges.

Vulcan Seals Type 1645B

Technical Data Sheet

Product Description

The Vulcan Seals Type 1645B is a robust, PTFE wedge-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 are 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 1645B complete seal is supplied with the Vulcan Seals Type 25 clamped in place stationary. The Vulcan Seals Type 1645B rotary is compatible with a wide range of Vulcan Seals stationary types.

Operating Limits

Why Choose the Vulcan Seals Type 1645B?

  • Step shaft design allows hydraulic balancing to be incorporated allowing high shaft speeds, higher pressures, and longer run time to be achieved compared to non-balanced seal designs.
  • Highly effective robust design that is commonly used in chemical and petrochemical duties.
  • PTFE wedge secondary seal, VCT1 carbon primary seal face, and Hastelloy-C276® springs ensure compatibility with a wide range of industrial medias.
  • The design features a setting line to aid installation at the correct compressed length.
  • Suitable for medium and heavy-purpose applications with imperial shaft sizes.
  • Vulcan Seals Type 1645B has a narrow radial profile to suit the American ANSI B73-1974 centrifugal pump dimensions standard.
  • Seal face dimensions ensure compatibility with a wide range of Vulcan Seals can stationary ranges.
