Vespel CR-6100, available from Fluid Seals is a carbon fibre reinforced polymer that replaces metal and other composite materials in valve seats, line shaft bearings, pump wear rings and bushings.
 
A customer who installed Vespel CR-6100 wear rings, throat bushings and pressure reducing bushings in two multistage gasoline shipping pumps was able to prevent pump failures while benefiting from a 7% efficiency gain and a 90% reduction in overall vibration levels. The pumps have been in service for over four years without failure, where the previous MTBR was 12 months.
 
Key features of the Vespel CR-6100 components such as non-metallic properties, low coefficient of friction, and excellent dimensional stability allow them to withstand short duration off-design conditions including start-up, slow-rolling, low-flow, cavitation, or run-dry situations. The pump remains available for service, resulting in potentially lower repair cost.
 
With these characteristics, clearance at wear components can be reduced, resulting in efficiency gains that lead to significant operating cost reductions, particularly when applied to populations of pumps.
 
Pumps with reduced clearance also exhibit lower vibration levels and reduced cavitation. Seals and bearings last longer, and the MTBR increases.
 
Vespel CR-6100 can be used to pump boiler feed, condensate, propane, butane, ethylene, LPG, diesel, gas, oil, sour water, naphtha, gasoline, MEA, DEA, sulphuric acid, ammonia, hydrofluoric acid, caustic and lube oil.
