Garlock ONE-UP® pump diaphragms make use of high performance GORE® ePTFE sheet on the wetted side for significantly longer life than conventional PTFE diaphragms. Aside from the vastly superior PTFE, additional strength is given to the diaphragms by utilizing a one piece construction where the ePTFE is physically bonded to a premium grade, fabric reinforced, elastomer backer. The ePTFE facing and elastomer backer both have patented surface features that help disperse stress and is another contributing factor to the diaphragms renown longevity. Garlock ONE-UP® diaphragms excel in applications that experience chemically aggressive process medias, abrasive wear, high pressures, and other pumping system obstacles that are often too extreme for stock OEM diaphragms.
