Regarding nitric acid pumps, is it better to choose stainless steel pumps or fluoroplastic pumps?
Nitric acid is a strong acid, so of course a fluorine pump is needed
Consider the specific conditions of nitric acid, such as concentration and temperature
Nitric acid is an oxidizing acid; it is recommended to use pumps made of PTFE, with magnetic pumps being the best choice.
It is recommended to use a shielded pump or a magnetic drive pump lined with PTFE, to prevent corrosion-related issues such as mechanical seal leaks once and for all.
Fluoroplastic magnetic pumps should be used. The CQB model not only possesses the advantages of conventional magnetic pumps, such as compact structure, attractive appearance, small size, low noise level, and reliable operation, but its flow-through components are all made from fluoroplastic, which is currently the material with the best corrosion resistance in the world. The isolation sleeve is fabricated from a special material with high mechanical strength, thereby eliminating the magnetic eddy current phenomenon associated with conventional magnetic pumps. Therefore, fluoroplastic magnetic pumps can transport corrosive media such as acids, alkalis, and oxidizers of any concentration (strength) without being damaged.

The transfer of nitric acid at low temperatures should, in theory, be possible using stainless steel pumps; to ensure reliability, it is recommended to use fluoropolymer pumps
