Garlock® ONE UP® Pump Diaphragm

Resistant to chemicals, abrasives, high temperature, and high pressure.

Garlock® ONE-UP® pump diaphragms contain high performance GORE® PTFE sheet on the wetted side for significantly longer life than conventional PTFE diaphragms. These diaphragms are considerably stronger than conventional materials and provide excellent chemical resistance. They are suitable for use in elevated temperatures and pressures, and are ideal for general-service pumps that are used for a variety of pumping tasks.
