FAQ

Can a plastic AODD pump handle sulfuric acid?

PP handles dilute sulfuric; for concentrated acid up to 98% choose PVDF or PTFE wetted parts.

What is the lifespan of a PP pump diaphragm?

With normal chemical service, 6-12 months; PTFE diaphragms last longer in aggressive media.

Do you offer PVDF pumps for solvent transfer?

Yes — PVDF handles most solvents, halogens and strong oxidizers.
