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.

Features and Benefits:

• In house testing shows Graco’s PTFE over-molded diaphragms outperforms the competitions.
• Over-molded 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.

Graco overmolded diaphragms are completely enclosed and feature smooth, flat surfaces which make maintenance and Clean in Place (CIP) processes quick and easy.
