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

Transfer and handle your dry process powders faster, cleaner and at a fraction of the cost associated with installed “systems.” Consistent trouble-free transfer of powders up to 45-lbs.

• Replaces Manual Powder Processes
• Reduce Airborne Contamination - With direct transfer from the powder container to your recipe
• Unique Patented Air-Induction System - Avoids the possibility of powder pack-out
• Portable - Can be moved from site to site

• All Investment Cast Wetted Parts
