IDG has developed two specific types of seals, the 444 profile as a complete seal for original equipment or complete overhauls, and the 449 split profile.

Features and applications

• Pivoting movement
• Single and double-acting sealing
• Radial compensation capability
• Adaptable to existing throat dimensions
• Max. pressure 40 MPa
• Developed for the sealing of Kaplan blades
• Also suitable for gudgeon sealing
• Suitable for water and oil
• Axis misalignments and eccentricity are compensated for by radial adaptability.
• Easy and efficient setup thanks to robust construction
• No Ø limits
• Joint cut for easier assembly (depending on type)
• For revisions, the system can be adapted to existing grooves.
