We've passed up the competition

Increase your plant’s efficiency with Graco’s overmolded diaphragms.

Our diaphragms last longer and are considerably stronger than other diaphragms. They can be used with most chemicals and are ideal for a wide range of pumping tasks.

 

  • In-house testing shows Graco’s PTFE overmolded diaphragms outperform the competition
  • Overmolded design improves wear and diaphragm life with no exposed diaphragm plate on the fluid side
  • Longer diaphragm life in more abrasive applications that still require PTFE
  • Available for Graco Sanitary and Industrial diaphragm pumps – 1040, 1590, 2150 and 3150
