AR® HT
TP热塑性塑料
Greene Tweed
产品描述
AR® HT is a proprietary thermoplastic material specifically developed for use as bushings, bearings, and wear rings in pumps handling abrasive media up to 250°F (121°C). ARHT provides outstanding chemical, thermal shock, and impact resistance, making it a better wear material than traditional rubberm ceramic or bronze materials.
Greene, Tweed's proprietary AR thermoplastics materials exhibit outstanding wear characteristics in media containing solids. AR combines excellent abrasive resistance, good dry run capability and superior vibration dampening characteristics with no hydrolysis or swell.
ARHT works well in a variety of abrasive pump applications including those working with circulating water, open and closed cooling water, river water, screen water and crude oil pumps. When using ARHT pump users can operater their equipment with much tighter clearances, boosting efficiency and improving process reliability.
