For nitric acid transfer, the choice of a centrifugal pump depends mainly on the concentration and temperature of the acid. Chemical-resistant materials are essential to avoid corrosion and leakage.
PVDF (Polyvinylidene Fluoride): Excellent resistance to nitric acid and temperatures up to approximately 90–100°C.
PTFE-lined pumps: Suitable for highly corrosive and concentrated nitric acid.
Polypropylene (PP): Generally recommended for dilute acid and temperatures up to 70–80°C.
SS316L: Suitable only for specific concentrations and temperatures; compatibility should be verified.
