In daily work, the author often encounters customer inquiries regarding the chemical compatibility of diaphragm pumps. However, among the various publicly available documents on the internet, evaluations of the same chemical medium often present contradictory or even conflicting statements from different sources. For instance, some documents rate it as "good," while others note "limited resistance" or "not recommended." Furthermore, many resources fail to specify critical operating conditions such as solvent concentration, temperature, and contact time—factors that are precisely the core variables determining whether a material is corrosion-resistant. A "compatibility table" lacking this information can easily mislead users, leading to incorrect material selection, premature diaphragm failure, or even equipment damage.
To help users make more comprehensive and objective judgments, the author has systematically collected and organized various publicly available chemical compatibility documents from the internet, consolidating them into the download area below. This compilation covers data from multiple major suppliers and standards organizations, aiming to provide users with a multi-angle reference tool that reduces the risk of selection bias caused by relying on a single information source. It is hoped that this effort will offer practical assistance to users in pump material selection and media matching.
