Hypro’s polypropylene diaphragm pump is built with polypropylene heads and manifolds for corrosion resistance and is designed for harsh chemical applications. The three-cylinder design eliminates the need for pulsation dampening devices, and lengthens the life of the entire pumping system. This poly diaphragm pump series has flow rates up to 11.0 gpm (41.6 lpm) and pressure to 290 psi (20 bar).
The poly diaphragm pump is built with external inlet and outlet manifolds compared to that of internal manifold design. According to Hypro, this allows for easy valve replacement and lower cost repairs. The oil sight glass is located in a protected spot, positioned at the top of the pump body, reducing the chance for breakage.
