ARO high pressure air diaphragm pumps were developed for applications requiring fluid pressures in excess of the 100 psi allowed by traditional pumps. Compared to a standard diaphragm pump, the 3:1 ratio high pressure diaphragm pump can produce up to 300 psi at about half the flow rate.

• Can produce up to 300 psi, at about half the flow rate of a standard diaphragm pump by utilizing two power pistons that drive the fluid handling diaphragms
• Generates nearly 300 psi on standard 100 psi shop air
• Stall-Free
• deal transfer of paint recirculation and high solid coatings, inks, adhesives, filled material, drilling grout, caulking, solvent reclamation and resins
