GRAPHALLOY® bushings and case wear rings can improve the reliability and efficiency of your API and non-API pumps. In horizontal and vertical pumps, self-lubricating, non-galling GRAPHALLOY won’t seize or gall if run dry or with marginal lubrication. GRAPHALLOY fitted pumps are able to survive upsets, dry running, loss of suction, slow roll on standby and other transient conditions that can occur when pumping low lubricity fluids and liquid gases. Using GRAPHALLOY allows closer clearances often gaining efficiency improvements, reduced vibration and reduced NPSH requirements. NSF® and WRAS certified grades are available. GRAPHALLOY materials work in temperatures from -450°F (-240°C) to 1000°F (538°C).
