Wear Mode: Blisters

Air bubbles or “blisters” seen on the surface of the elastomer. They are caused by gas absorbed by the rubber under pressure and the pressure is released quickly, causing explosive decompression.

Chunking occurs when the elastomer has been over-loaded and has fatigued, tearing away from itself.

Ribbing is a mechanical type of failure where gouges, dents or depressions have been worn into the lobes.

Splitting occurs when the elastomer shows cracks in the rubber but has not yet chunked.

Effective wear management depends on selecting the optimum elastomer for the application and recognizing when remedial action is required. Your PV Fluid Products representative can offer advice on the causes of wear and solutions.This will help you reduce your cost of ownership and improve your operating hours.
