Diaphragm Overview
Diaphragms are essential components in pumps, valves, and sealing systems, widely utilized in industrial and commercial applications. Made from materials such as rubber and PTFE, they offer excellent chemical resistance and high-temperature endurance. Diaphragms provide reliable flexibility and durability, adapting to high-pressure and corrosive environments to ensure efficient operation and extended service life.

LAN SHIUON produces three main types of diaphragms designed for pumps, valves, and burst disk assemblies. In our diaphragm manufacturing, we use high-density, high-strength, and high-flexibility PTFE-filled materials to enhance performance under demanding conditions.


Advanced Diaphragm Technology
For pneumatic diaphragm valves, where reducing pneumatic tension is critical, the diaphragm’s design may require extended development time. LAN SHIUON has addressed this challenge by integrating a layer of rubber into the PTFE diaphragm, compensating for PTFE’s limited elasticity. While rubber alone may have lower strength, we reinforce it with non-woven fabric, significantly enhancing both strength and resilience. This technology exemplifies our commitment to high-quality production in diaphragm manufacturing.

Superior Production Standards
Our diaphragms are produced in a single process within vacuum molds, ensuring a level of quality that surpasses industry standards for diaphragm pumps. In pump operation, diaphragms are generally considered consumables. While pure PTFE diaphragms may experience unusual cracking, our high-quality diaphragms typically undergo controlled breakage only after extended use. Each diaphragm undergoes high-resilience polymer testing to ensure durability, with smaller sizes rated for approximately 18,000,000 to 30,000,000 cycles, and larger sizes rated for 6,000,000 to 8,000,000 cycles.

This rigorous testing and advanced material selection allow us to provide diaphragms that meet the highest performance and reliability standards for industrial applications.
