The Bürkle Double-Diaphragm Pump in PVDF/PTFE provides a liquid-transfer option with a defined combination of wetted materials. This version uses PVDF for the housing and valve seats, with PTFE valve balls and seals. Select the pump according to the liquid and operating conditions of the intended application.
The PVDF/PTFE material configuration helps distinguish this model from other Bürkle double-diaphragm pump variants. Match all wetted materials, connections and operating requirements to the planned transfer process.
It is used for transferring liquids in a compatible pumping setup. Suitability depends on the liquid properties, required transfer conditions and the materials in contact with the liquid.
