Maximum reliability at the highest pressure & speed

The 1000 Series Rotary Joint is designed for the highest pressure and speed applications. Engineered specifically for the paper industry, it delivers exceptional sealing performance, maximum reliability, and long service life in demanding operating conditions.

Key features

Ten features engineered for high-speed paper machine duty

The 1000 Series combines flow configuration flexibility with a balanced seal design engineered specifically for the run-out, thermal expansion, and flow demands of high-speed paper machines.

Single & dual flow condition

Available for different steam, water and condensate transfer applications.

Cantilever stationary syphon service

Designed for cantilever stationary syphon service applications.

Balanced multi-spring design, optimised pressure

Balanced multi-spring design provides optimized pressure and reliable sealing performance.

Large full flow area, low pressure loss

Large full flow area helps maintain efficient flow with low pressure loss.

Accommodates thermal expansion

Design accommodates thermal expansion during high-temperature operation.

Seal permits run-out & misalignment

Seal design allows for run out and misalignment during operation.

Seal under compression load

Seal operates under compression load for reliable sealing performance.

Various sealing grades available

Different sealing grades are available according to the application.

For high speed paper machines

Specially designed for high speed paper machine applications.

Reduces installation time

Design helps reduce installation time and simplifies installation.

Balanced multi-spring seal

Sealing that moves with the machine, not against it

At the speeds and pressures the 1000 Series is built for, the seal has to tolerate movement rather than resist it — run-out, misalignment, and thermal growth are treated as normal operating conditions, not faults.

Balanced multi-spring seal, loaded evenly under compression around the seal face
  • Optimised pressure via balanced multi-spring loading

    The balanced multi-spring design provides optimized pressure and reliable sealing performance, distributing load evenly rather than relying on a single spring point.

  • Compression loading, tolerant of run-out

    The seal operates under compression load, with a design that permits run-out and misalignment during operation — conditions that are unavoidable at high speed on a large paper machine cylinder.

  • Built-in thermal expansion accommodation

    The design accommodates thermal expansion during high-temperature operation, keeping the seal interface stable as the machine heats up and reaches full running temperature.
