• Does not stall or cavitate: Unlike a centrifugal pump, the pneumatic diaphragm pump can operate at any flow rate without cavitation, and the fluid is not at risk of vaporizing since the pressure in the chamber will never be lower than the fluid's vapor pressure. Fluimac S.r.l. has long produced double diaphragm pumps and has developed a method to separate the feed from the pump body, making assembly less difficult and reducing the risk of stuck parts, gaskets, and o-rings, while increasing air passage channels reduces the risk of pneumatic pump stalling. Moreover, increasing the number of tightening screws has reduced the risk of pump leaks, providing greater compression to the gaskets;
  • Self-priming: Thanks to this feature, the diaphragm pump can suck fluid even if placed above the free surface, even when dry, i.e., without initial liquid, up to 4 meters high. It does not risk temperature increases and/or friction that damage the pump and membranes. If already primed, it can suck liquid from 9 meters and pump up to 9.8 meters high on primed suction;
  • No electricity required: For powering the pneumatic diaphragm pump, an air compression system (range between 1 and 8 bar) is needed, which can sometimes be an advantage due to the absence of electricity near the liquid;

  • Capable of processing almost all types of existing fluids: As the diaphragm pump is driven by compressed air, with wider and varied fields and usage pressures, the pumping chambers fill and empty regardless of the worked liquid, moving even very dense or viscous substances. With double diaphragm pumps, it is possible to process highly acidic, corrosive, or alkaline liquids, paints, glues, high viscosity liquids up to 50 CPS, food products, or liquids with solid particles up to 2 mm in diameter in the smaller configurations, and up to 12 mm in the larger ones. Using pneumatic diaphragm pumps for fluids with maximum allowed viscosity leads to a decrease of up to 90% of the nominal flow rate;

  • Easily adjustable: It is possible to vary the flow rate easily by decreasing the pneumatic air load at the inlet, or by closing the suction manifold. Thanks to this feature, the PHOENIX double diaphragm pneumatic pump is adaptable to different types of systems: based on the supply pressure, from 2 bars to 8 bars, it is possible to obtain different characteristic curves;
  • Adaptable and versatile: based on the application field, it can be modified as needed
