What are Pump and Valve Diaphragms?
Pump and valve diaphragms are flexible, rubber parts that provide a crucial function in fluid control systems. They act as a barrier between two chambers, moving up and down to control the flow of fluid or gas. This movement is what allows pumps and valves to regulate pressure, flow rate, and direction.

Why Choose Exactseal’s Pump and Valve Diaphragm?
Our pump and valve diaphragms are crafted with precision and durability in mind. We use high-grade rubber materials that can withstand different operating conditions, including high temperatures, pressures, and corrosive substances. This ensures that our diaphragms deliver reliable performance and longevity.
