New ROTARSEAL external sealed rotating joint, based on the previous model but with technical updates.

Technical updates:

  • Air pressurization need has been removed.
  • Maximum rotation speed with water increased up to 10,000 rpm.
  • A life-lasting greasing has been added as the periodical fat addition is not required.


  • The pressurization removal will avoid the use of compressed air and its related system, with the result of an easier and cheaper machine concerning installation, maintenance and replacement.
  • Easier installation, just to screw the joint to the shaft, no further actions needed.
  • In case of replacement, it is NOT necessary to connect any pressurization pipe and the relative air flow can be off.

  • Water connection: G ¼”
  • Fixing to the shaft connection: M16x1,5 LEFT
  • Maximum water pressure: 3 bar
  • Maximum water flow rate: 15 liters per minute
  • Maximum dry speed: 3.000 rpm

For technical clarification and information the project manager is Eng. Marco Povolo.
