Poly Diaphragm Pumps

These polypropylene smooth-operating, three-cylinder diaphragm pumps achieve a max of 20.2 gpm (76.4 lpm) and max of 290 psi (20 bar).

  • Glass-filled polypropylene construction of head, manifold and control components for the maximum in chemical resistance 
  • Flow rate up to 11.5 gpm (43.3 lpm), 15.6 gpm (59 lpm) and 20.2 gpm (76.5 lpm) pressure up to 290 psi (20 bar)  
  • 3 cylinder design eliminates the need for pulsation dampening devices and lengthens the life of the entire pumping system Kynar ™ and 300 series stainless steel valve design for higher flow and better corrosion resistance
  • The external inlet and outlet manifold design vs. an internal manifold design
