AxFlow UK has a variety of pumps, valves avaialbale in PTFE.
PTFE (Polytetrafluoroethylene) reduces friction, wear and therefore energy consumption of pumps as it has one of the lowest coefficients of friction against any solid. PTFE is a thermoplastic polymer with excellent chemical resistance . PTFE pumps are suitable for handling almoist any kind of liquid despite its viscousity, chemical aggressive or with solids- they will handle even the most aggressive acids, for instance concentrated nitric acid. Maximum liquid temperature is up to 100°C. Typical applications include, chemical industries, food and beverage and water treatment.
