Operational and Safety Benefits of Vespel® CR-6100 Wear Parts


DuPont™ Vespel® CR-6100 mitigates the risk of damage from wear ring contact, which can result from mechanical failure,

offdesign operation, or dry running.  
When metal wear rings contact, the extreme friction generates heat, the materials gall (friction weld),

and the pump can seize. This is potentially a high energy, dangerous  
situation, which can result in extensive equipment damage and

potential release of process fluid to the atmosphere. Vespel® CR-6100 wear rings minimize the risk of galling  
or seizure, thereby reducing

the consequences of failure and risk of damage to expensive cast metal parts, reducing repair costs.

Vespel® CR-6100 wear rings also minimize  
the impact of rundry conditions. Pumps resist seizure during periods of suction loss,

off-design operation, slow rolling, or start-up conditions. When the upset condition has  
been corrected, the pump can frequently continue in service

without further damage or loss of performance. Conversely, pumps with metal wear rings exposed to these  
conditions frequently experience galling and seizure

, requiring removal from service, disassembly, and repair.
