Select pump materials and seals by the fluid pumped. For common process fluids and chemicals this matrix gives the recommended pump type, the wetted materials to use and to avoid, the recommended seal type and the maximum service temperature — a fast wetted-materials check before specifying a pump for corrosive, abrasive or high-temperature duty.
Choosing the right materials of construction protects a pump against corrosion, erosion and product contamination, and it is usually the difference between a unit that lasts twenty years and one that fails in months. Every wetted part matters — casing, impeller or rotor, shaft, wear rings and, critically, the elastomers and seal faces, which are often the first components to fail in an incompatible service.
Cast iron and bronze suit clean water and many neutral duties; stainless steels (304/316) handle mild chemicals and food contact; duplex and super-duplex, titanium, nickel alloys and non-metallics (PVDF, PTFE-lined, polypropylene) are reserved for seawater, acids, oxidisers and aggressive chemicals. Seal selection follows the fluid: single mechanical seals for clean liquids, double or cartridge seals with a flush plan for hazardous, abrasive or volatile media, and seal-less magnetic-drive or diaphragm pumps where zero leakage is mandatory. Always confirm the maximum service temperature, because both metal allowables and elastomer ratings fall sharply with heat.
