Understand ss316 or any metals is not suitable to handle acid,
Please advise any suitable pump materials that could resist this hydrochloride acid
Other chemical would be sulfuric acid

RE: Chemical compatibility of hydrocloride acid
The concentration, temperature, impurities, and mechanical stresses must all be taken into account.
Design for acid service is not for amateurs.

Endstainless:
Impurities,mechanical stress, temp, concentration does it directly proportional to corrosiveness of the casing material ?
RE: Chemical compatibility of hydrocloride acid
Concentrated HCl acid at 80 C is best handled in Teflon-lined equipment. If you must use metals, your choices are Hastelloy B, zirconium or tantalum. Both HB and zirc are only resistant if there are no oxidizing ions like Fe+3 present. There are no other choices I'm aware of.
Be aware also that the velocities in pumps are high, so erosion-corrosion can be an issue. You're far safer with the lined construction.
