You own the premier AODD pump. Keep it operating at peak performance with diaphragms from Wilden. Genuine Wilden - Accept Nothing Less.

The right diaphragm for your air-operated double-diaphragm (AODD) pump is a critical consideration to ensure a safe, efficient, cost effective and trouble-free operation.

This is why as the inventors of AODD pump technology, Wilden® offers the largest selection of diaphragms in the world specifically designed to enhance pump performance and provide long flex life, significant labor savings and superior durability. With a diaphragm for every industry – from aggressive chemicals to highly abrasive materials to extreme operating temperatures – Wilden ensures that your unique application is fully met with the best possible diaphragm to optimize chemical compatibility, life, flow, suction lift, temperature limit, abrasion resistance and cost.

How to Select Your Diaphragm

Determining the correct diaphragm requires carefully identifying and factoring all process and application parameters into the analysis. A number of factors must be taken into account when choosing the proper diaphragm suitable for a specific application.

Chemical Resistance

Material compatibility with the fluid being pumped

Temperature Ranges

Capability to remain flexible in low temperatures and not deteriorate in high temperatures

Abrasion Resistance

Ability to withstand wear and friction from contract with solids and particles in the fluid being pumped

Sanitary Standards

Requirements that the diaphragm comply with hygienic or sanitary standards.

Flex Life

Expected longevity of the diaphragm before requiring replacement


Total cost of ownership determined by multiple factors such as initial price, rated flex life for the application and costs of downtime and diaphragm replacement labor
