Servo motor

In hydroelectric power plants, servomotors control all opening, closing, steering, and regulation functions.

They must hold their positions irrespective of the pressure.



Features and applications

• Linear movement
• Single-acting seal with scraping (depending on type)
• Adaptable to existing throat dimensions
• Max. pressure 40 MPa
• Developed by the sealing of Pelton injector rods or servo motors
• Pressure-reducing scraping lip to minimise friction (depending on type)
• Also suitable for sealing rotating rings
• Suitable for water and oil
• Low wear for infrequent maintenance
• Feasible up to Ø 3000 mm
