Garlock manufactures the most durable and long-lasting pump and valve diaphragms available, reducing equipment downtime and increasing productivity. From pure PTFE to one-piece bolt-on PTFE bonded rubber diaphragms, if you have a difficult or critical application, Garlock has the diaphragm to meet your needs.

 Garlock ONE UP® Pump Diaphragm

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.
