Canned motor pumps are widely used in various processing industries to transport hazardous fluids. Vespel® CR-6100 parts have been demonstrated to survive run-dry conditions, with low wear rates , extending mean time between repairs of the retrofitted pump
Vespel® SCP-5050 sweep-out fingers and stacker bar inserts for glass handling help increase plant reliability and efficiency and reduce operating costs at Veda-Pack glass manufacturing sites
Retrofitting the pumps with DuPont™ Vespel® CR-6100 parts for line shaft bearings and stationary wear rings. To demonstrate that Vespel® CR-6100 could survive these conditions, site personnel installed a retrofitted pump and performed a field test.
The operator installed Vespel® CR-6100 parts as stationary wear components in boiler pumps. Clearance is about half that of the original design specifications of 0.016 in. (0.406 mm) for metal parts.
The operator of a pipeline in the Southwestern U.S. was searching for a case ring material for pumps that would enable improved operating efficiency, increase equipment reliability and avoid the seizing or galling problems encountered with metal components. The metal components were replaced with Vespel® CR-6100 parts, and the results were impressive.
