AF0F0170SHTTST3
Air-operated double-diaphragm pump • Tri-Clamp 1½″ • SS316 stainless steel / Hytrel/PTFE / PTFESEKO Duotek AF0170 is an air-operated double-diaphragm pump for transferring chemicals, viscous media and liquids containing solids. Version AF0F0170SHTTST3: SS316 stainless steel body, Hytrel / PTFE diaphragms, PTFE balls, SS316 seats and PTFE O-rings.
Performance is adjusted by the compressed-air supply. Selection depends on the required flow at actual back pressure, suction conditions, viscosity and chemical compatibility of all wetted materials.

Materials and operating limits
Five material fields define the wetted assembly. The body material alone is not sufficient to assess chemical compatibility of the complete pump. Chemical resistance →
Material of the fluid chambers and manifolds. Chemical resistance must be checked for the actual liquid and temperature.
Air-side and fluid-side diaphragm in this configuration. The wetted side must be compatible with the liquid.
Check-valve ball material; it affects chemical resistance and reliable valve closure.
Valve-seat material in this configuration.
O-ring and sealing material; compatibility with all liquid components must be verified.
Select the duty point from the performance curve using actual back pressure, suction conditions and viscosity.
