FAQ

What chemicals can a PTFE AODD pump handle?

Nearly all aggressive chemicals including 98% sulfuric acid, aqua regia, solvents and halogens.

Is PTFE safe for food contact?

PTFE is FDA-listed for food contact; for sanitary service we also offer SS316 with PTFE diaphragms.

Why choose one-piece PTFE diaphragm?

One-piece construction prevents permeation failure in halogen and strong acid service.
