Questions about AODD diaphragm pump membranes

Quick enquiry for pump spare parts

What materials are used for AODD diaphragm pump membranes?
Common materials are PTFE (high chemical resistance), Santoprene (general purpose, cost-effective), Buna-N (oil resistant), Neoprene and EPDM (resistant to dilute acids/alkalis). Select based on fluid chemistry, concentration and temperature.
How often should diaphragm pump membranes be replaced?
Reference interval: 6–18 months depending on fluid type and duty cycle. PTFE membranes offer greater chemical resistance but less flexibility than Santoprene; select according to application.
