Pump breakdowns have a significant impact on cost and productivity. The components under rotational loads like shaft & bearing play a major role in deciding pump reliability. Proactive maintenance can reduce the risk of breakdowns and increase pump service life.
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
