Graco designs and manufactures a line of PTFE and EPDM overmolded diaphragms to fit our double diaphragm transfer pumps. The diaphragm immediately improves the efficiency of your pump. Use with most chemicals in transfer applications. Additionally, experience longer diaphragm life in more abrasive applications that still require PTFE.
AVAILABLE IN NUMEROUS SIZES
IMPROVE DIAPHRAGM LIFE WITH OVERMOLDED DESIGN
Graco’s overmolded design improves wear and diaphragm life with no exposed diaphragm plate on the fluid side. 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. These high-quality diaphragms are available in numerous sizes: ½ inch, 1 inch, 1½ inch, 2 inch and 3 inch.
We design our diaphragms for flexibility. Not only are they available in multiple sizes, but you can use them with most chemicals, including abrasive and corrosive materials.
Reduce Replacement Part Costs
Graco’s higher-quality diaphragms last longer on the job than the competition, which reduces your replacement parts costs over time. The overmolded design improves wear.
