AODD Pump Material Selection Guide
Material selection is a system decision. The body material alone does not establish chemical compatibility, abrasion life or suitability for a duty.
1. Record the complete fluid
Provide the chemical or product name, composition, concentration, operating and cleaning temperatures, viscosity, solids, particle size and any batch-to-batch change. Include the cleaning liquid because it contacts the same wetted parts.
2. Check every wetted component
Review the pump body and manifolds together with diaphragms, balls, seats and seals. A compatible housing does not make an incompatible elastomer acceptable. Use documented compatibility information and confirm uncertain mixtures with the material supplier or a controlled test.
3. Separate corrosion, wear and hygiene
Chemical resistance, abrasion resistance, conductivity, cleanability and required surface finish are different questions. Stainless steel, aluminium, polypropylene and other options must be evaluated for the actual duty rather than ranked as universally better or worse.
4. Confirm the selected model
Before ordering, confirm the exact wetted-parts list, pressure and temperature limits, connection, grounding needs and cleaning method for the quoted configuration. Do not transfer limits from another size or material option.
Source basis and limits
This guide is based on general AODD operating principles and the DELEEMA selection workflow. Model-specific performance, materials, dimensions and limits must be checked against the applicable model data and the configuration confirmed in writing.
