Material selection of diaphragm pump

In the field of fluid delivery, the AODD PUMP is a widely used device whose performance and life are closely related to the choice of material. The material choice of pneumatic diaphragm pump is not only related to service life and performance, but also directly affects the reliability and efficiency of industrial processes. This article will discuss the material selection of saiken pump’s diaphragm pump in depth, in order to provide valuable reference for engineers and designers.

First, we focus on the core component of the diaphragm pump – the diaphragm. The diaphragm is subjected to frequent deformation and stress during the operation of the pump, so its material selection is crucial. Common diaphragm materials include fluorine rubber, polytetrafluoroethylene (PTFE), butadiene rubber and so on. The diaphragm of different materials has differences in chemical stability, wear resistance and elasticity, so it needs to be selected according to the specific process conditions and the characteristics of the transport medium.

Fluororubbers and PTFE are common choices when it comes to corrosion resistance. Fluorine rubber has excellent chemical corrosion resistance and is suitable for many acid and alkali media. PTFE, due to its excellent corrosion resistance, is often used to transport highly corrosive media, such as strong acids, strong bases and so on.

In addition to the diaphragm material, the pump body and valve body material of the diaphragm pump are also crucial. In general, metal, plastic and composite materials are common pump body and valve body materials. Metal materials such as stainless steel and cast iron are superior in strength and durability, and are suitable for some harsh working conditions. However, for some metal-sensitive media, it may be more appropriate to choose plastics such as polypropylene or composite materials.

In practical engineering, the selection of materials needs to consider many factors such as the nature of the medium, the working environment, and the operating pressure. The pursuit of corrosion resistance alone may neglect other performance indicators, so a comprehensive evaluation is required when selecting materials. The excellent performance of the diaphragm pump depends not only on its design and manufacturing process, but also on the reasonable material selection to provide reliable support for industrial production.
