The process – from analysis to return delivery
1. Initial consultation & quote
In the first step, a phone call or a short message with a few photos or technical drawings is often sufficient. Alternatively, the defective component can also be delivered directly to us or inspected at your premises.
Our experts analyse the condition and determine the repair options. On this basis, we prepare a transparent, binding quote – with no hidden costs.
2. Collection & analysis
If you wish, our service team will take care of all the logistics. Depending on the location and condition of the rotor, we offer two options:
- The rotor is dismantled, documented and reconditioned on site.
- Or we organise transport to our factory, where a detailed analysis including measurement and material testing is carried out.
3. Repair / New production
Our repairs are carried out using methods that are true to the original and comply with the manufacturer’s specifications. We use high-quality materials, modern processing methods and over 175 years of mechanical engineering expertise.
If a repair is not technically or economically feasible, we can manufacture a custom-fit new rotor on request, including dynamic balancing and optional hardfacing.
4. Quality control & return shipping
Once the work is complete, we subject each rotor to rigorous quality control. On request, testing and balancing can be carried out directly at your premises or at our factory. You will receive detailed documentation including a test report. Optionally, our experts can supervise the installation or carry it out completely.
