FAQ

How often should AODD pump diaphragms be replaced?

In aggressive chemical service, every 3-6 months; in light service, 12-24 months. Replace when flow drops or stall occurs.

PTFE vs Santoprene diaphragm — which do I need?

PTFE for aggressive chemicals; Santoprene/EPDM for general water, mild chemicals and food service.

Do you sell one-piece or overlay diaphragms?

Both — one-piece PTFE for halogen/strong acid service, overlay for standard chemical duty.
