Pump MOC Selection Guide
Select the correct pump material of construction for your chemical application. Filter by chemical, MOC, or temperature range.
Stainless Steel SS316
Applications: chemical processing, pharmaceutical, marine. Contains 2–3% Molybdenum for pitting resistance. Max temp: 300°C. Critical warning: Incompatible with all chloride compounds — HCl, FeCl₃, NaOCl. Will stress-corrosion crack rapidly.
Polypropylene (PP)
Applications: HCl, NaOH, H₃PO₄, most non-oxidising acids and bases. Max temp: 70°C–100°C. Not suitable for: oxidising acids, aromatic solvents (toluene, xylene), temperatures above 100°C.
PVDF (Kynar)
Applications: HF, HNO₃, oxidising agents, halogens, concentrated acids where PP fails. Max temp: 135°C. Premium material — specify when both chemical aggressiveness and elevated temperature exceed PP limits.
