Is your machine down or not running as usual? We find the cause and repair homogenising mixers, homogenisers and mixing and homogenising plants – on site at your plant or in our workshop in Weyhe, worldwide.
How we help with a breakdown
- Report the case: via our service request form or by phone. Type, fault description and photos help us prepare.
- Initial assessment: together we decide whether an on-site repair or a workshop repair makes more sense.
- Preparation: we plan technicians, tools and the spare parts needed.
- Repair: we repair the machine and check that it works.
- Recommendation: on request, we show you how planned maintenance can prevent similar failures.
After a crash: rotor, stator and shaft
If a foreign body gets between the teeth of rotor and stator, a crash can occur and the teeth are damaged. Rotor, stator and shaft then have to be replaced. For homogenisers from Vakumix and NETZSCH Vakumix we supply matching spare parts and fit them on request.
Typical faults
Homogeniser & agitator

The sooner you tell us the type, year and fault, the better we can prepare the visit.
