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.
