Chemical acidic centrifugal pump ?

[bmw318be]

Any reliable centrifugal pump that is competitive to handle hydrochloride acid ?

Plenty of them. Not the least of which would be Goulds & Flowserve(Durco); many, many other as well. You probably will want to look at a non-metallic pump, of which there are very many with long successful track records / installations.

Magdriven centrifugal pumps. Just Google that and you will get plenty of results.

Goulds 3298 tefzel lined mag drive pump.

Other than leading brand flowserve and goulds, what is the internal material would be for casing or impeller ?

 

[micalbrch]

Plastic (PP, PVFD, PTFE), depending upon acid concentration, flow and head of the pump.

I would recommend looking into mag-drive pumps, as those prior to me have also said.

I have had success with Goulds 3298, Innomags, and even Sundyne ANSI-Mags. All mag-drive pumps, each with their own pros and cons. At this time I don't have an opinion of one over the other, as I have the 3298's in HCl service, the Innomags in NaOH, and NaOCl service and the ANSI-Mag in H2SO4 service. I would also take a look at IWAKI M Series mag-drive pumps and also possibly UltraChem. I haven't had any experience with those, but they are likely worth looking into as it is always good to have options to compare. Good luck.

This question was previously asked and answered: mag-driven Teflon lined pumps are the normal tool for this job.
