Material Notes:
Sand and other abrasives are often a challenge for pump users in the power industry. Clearances on line shaft bearings and bowl wear rings open up, increasing pump vibrations and reducing pump efficiency. Greene Tweed’s proprietary AR™ thermoplastic materials exhibit outstanding wear characteristics in media containing solids.AR1 offers excellent abrasive resistance as well as chemical resistance approaching that of PTFE. AR1 is rated from ambient to 120°F (49°C). AR1 is easy to machine, and clearance requirements are easily determined. AR1 works well in a variety of pumps in the power industry including those working with circulating water as well as screen wash pumps. AR materials have performance characteristics that exceed traditional technologies such as cutlass rubber, bronze and carbon materials.Applications:Circulating water pumpsOpen and closed cooling water pumpsRiver water pumpsScreen wash pumpsSump pumpsInformation provided by Greene Tweed.
