Water jet suction pump type P20 SYGEF Standard PVDF

  Datasheet (PDF)

Manufactured by Georg Fischer, the SYGEF Standard water jet suction pump type P20 is an engineered thermoplastic liquid-jet ejector designed for vacuum generation, chemical dosing, suction conveyance, and inline fluid mixing in demanding industrial piping installations. Operating on the hydrodynamic Venturi principle, the device utilizes a pressurized motive liquid stream accelerated through a precision internal nozzle to create a localized low-pressure vacuum zone in the mixing chamber, continuously drawing in gases, vapors, or secondary liquids through the suction branch without requiring dynamic seals or moving mechanical parts. Constructed entirely from premium-grade polyvinylidene fluoride (PVDF), the pump exhibits outstanding resistance to aggressive chemical environments, including oxidizing and non-oxidizing acids, halogens, aliphatic hydrocarbons, alcohols, and chlorinated solutions across an operational service temperature range extending from -20 degrees to 140 degrees Celsius. Engineered for system integration across nominal pipe diameters from d16 up to d90 (DN10 to DN80) with a nominal pressure rating of PN10, the assembly incorporates versatile jointing geometries: dimensions DN10 through DN50 feature detachable union ends with metric fusion sockets and high-integrity FKM elastomeric O-rings for rapid servicing, while larger dimensions DN65 and DN80 utilize direct metric fusion spigot ends suitable for robust socket or butt fusion joining methods. The wear-free monolithic PVDF fluid path provides exceptional dimensional stability, high mechanical rigidity, and hydraulic reliability, making the unit an ideal solution for wastewater aeration, chemical reagent dilution, vacuum sampling, degassing, and dosing in semiconductor manufacturing, chemical processing, pharmaceutical water loops, and heavy utility systems.
