At DYI SHENG, we specialize in the design and manufacturing of Air-Operated Double Diaphragm (AODD) Pumps and high-quality spare parts. We know that for international buyers, pump purchasing decisions are not only about the machine itself—but also about how durable, easy-to-maintain, and quickly replaceable the parts are. Reliable spare parts mean fewer interruptions, smoother operations, and better long-term cost savings.

Maximize Reliability – Prevent failures caused by wear or aging, ensuring uninterrupted production.

Reduce Ownership Costs – Standardized designs allow fast replacement, lowering maintenance and spare parts inventory costs.

Q1: Why should I choose OEM spare parts?
A: Original parts are specifically engineered and tested to deliver the best sealing performance and durability, preventing costly failures and reducing total cost of ownership.

Q2: How often should diaphragms and valves be replaced?
A: Replacement frequency depends on fluid type, application, and operating conditions. With the right materials, diaphragms can last significantly longer. Valves should be inspected and replaced if shifting becomes irregular or efficiency decreases.
