Maintenance, repair and overhauls for mechanical turbo gear units,
diaphragm couplings, rotor turning gear units on site

Fast and reliable

Drivetrain machines must run reliably! This also applies to both gearboxes and connection couplings. Besides our reliable world class maintenance, our goal in your plant is to complete overhauls and/or repair work quickly, cost-effectively, and thoroughly.

Maintenance / overhaul

    With regular maintenance and the replacement of wear parts in accordance with our recommendations - proven over many years - you retain or increase the availability of your turbo gear unit. This is verified by our customer surveys. These measures, adjusted according to the age and/or operating time, supplement your routine daily and weekly monitoring activities.

    Besides turbo gear units from different Voith brands, we also maintain and overhaul the turbo gear units of all well-known manufacturers.

    Do your turbo gear units run without problems? Excellent! Ensure that they keep running that way with a short qualified ‘health-check’ from Voith including a risk assessment? You can then be assured that your turbo gear remains problem free for a long time. Regardless of the manufacturer, we evaluate your complete inventory of turbo gear units.
