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.
