Superior sealing performance, extended seal life

The 801 Series Rotary Joint is engineered for high-pressure hot water and steam applications. Designed for demanding operating conditions, it provides superior sealing performance, extended seal life, and reliable operation under heavy loads.

Key features

Built specifically for medium grade paper machine duty

The 801 Series combines flow and syphon configuration options with external support and a dual sealing arrangement built for heavy-load, high-pressure paper machine service.

Single & dual flow condition

Available for different steam transfer applications.

Stationary & rotary syphon condition

Suitable for both stationary and rotary syphon applications.

Two lugs for external support

Two lugs are provided for external support and secure installation.

Spheroidal graphite cast steel housing & SS working parts

Robust construction provides reliable performance and durability.

Carbon graphite concave type two sealing rings

Two concave type carbon graphite sealing rings provide reliable sealing performance.

Various sealing grades available

Different sealing grades are available according to the application.

Adjustable syphon clearance option

Adjustable syphon clearance allows flexibility to suit different application requirements.

Specially for medium grade paper machines

Designed specifically for medium grade paper machine applications.

Two lugs & dual sealing rings

External support and sealing redundancy, built for heavy loads

The two external support lugs and the two concave sealing rings work together to carry heavier loads and sustain sealing performance under high-pressure, continuous paper machine duty.

Two external support lugs either side of the body, with two concave sealing rings at the seal interface
  • Two lugs for secure external support

    Two lugs are provided for external support and secure installation — important where the joint carries additional mechanical load from a heavier paper machine assembly.

  • Two concave sealing rings for sustained performance

    Two concave type carbon graphite sealing rings provide reliable sealing performance, giving the joint sealing redundancy at the high pressures and heavy loads typical of medium grade paper machine service.

  • Adjustable syphon clearance

    An adjustable syphon clearance option allows flexibility to suit different application requirements, without needing a different joint configuration for each installation.
