Selecting the correct body material is one of the most important steps when choosing an air-operated double-diaphragm pump.<\/p>\n

Aluminum, stainless steel and polypropylene AODD pumps may offer similar basic operating principles, but they are designed for different fluids and working environments. Choosing the wrong material can lead to corrosion, contamination, leakage, premature component failure or unnecessary equipment cost.<\/p>\n

There is no single material that is best for every application.<\/p>\n

The correct choice depends on the chemical properties of the fluid, operating temperature, solids content, cleaning requirements, installation environment and safety requirements.<\/p>\n

This guide compares the three most common AODD pump materials and explains when each one should be considered.<\/p>\n
