GRAPHALLOY® is an alloy of carbon graphite and metal. The
graphite provides continuous lubrication without the need for grease
oil or other forms of lubrication. GRAPHALLOY deposits a thin film of
graphite on the shaft to reduce friction and the metal impregnate help
to transfer heat from the rubbing surface to the housing. GRAPHALLOY
has much higher temperature limits than many thermoplastics available
today. Run-Dry transients will not melt the GRAPHALLOY as it may do to
other materials. Normally the pumps can be put back in service
immediately after dry running transients while plastics usually require
replacement.
