Air-Operated Double Diaphragm-AODD pump

Verderflex VA25 SS SS TF TF

Used Verderer VA25 Air-Operated Double Diaphragm (AODD) pumps with Stainless Steel configurations. The specific arrangement code you provided (VA25 SS SS TF TF) designates a heavy-duty metallic pump constructed with a Stainless Steel fluid section, Stainless Steel seats, and PTFE (Teflon) balls and diaphragms and defines a heavy-duty, highly corrosion-resistant configuration of the Verderair VA 25 Air-Operated Double Diaphragm (AODD) pump. This specific model is typically engineered to handle aggressive chemicals, strong acids, solvents, and high-temperature fluids

SS (Air Section / Check Valve Seats): Depending on the generation, this represents a heavy-duty Stainless Steel center air section or Stainless Steel valve seats. It avoids the corrosion or cracking risks associated with aluminum or plastic components in harsh environmental conditions;
TF (Check Valve Balls): PTFE (Teflon) check balls. Ensures a tight seal and broad chemical compatibility during cycling;
TF (Diaphragms): PTFE (Teflon) diaphragms (typically backed by an EPDM layer for flexibility). PTFE offers the highest level of universal resistance to corrosive fluids;
