Common challenges related to
cylindrical assemblies in
an industrial pump
Apparent causes behind these challenges
- Dynamic loading
- Severe service environments
Root Cause
Despite high interference and machining, there’s only 20-40% metal to metal contact. The rest is gap which allows:
- Dynamic loads to loosen the fit
- Air to get trapped in the interface causing fretting corrosion
loctite solution
Loctite 641
Medium strength retaining compound that fills all gaps between the cylindrical components and solidifies to unitize them, thereby:
- Unitizing
bearing & shaft - Preventing
fretting corrosion
Results
- High strength joint
- Protection against corrosion
- Component and Pump reliability ensured
