Overview
The ARO high pressure air diaphragm pump was developed for applications requiring fluid pressures in excess of the 100 psi allowed by traditional pumps. Compared to a standard diaphragm pump, our 2:1 ratio high pressure diaphragm pump can produce up to 200 psi at about half the flow rate.
The 2:1 ratio is accomplished by using the effective surface area of both diaphragms to double the output pressure.
Features
- Utilizing Power – Can produce up to 200 psi, at about half the flow rate of a standard diaphragm pump. Our high pressure air operated diaphragm pump utilizes the effective surface areas of both diaphragms to double output pressure.
- Structural Integrity – Bolted construction eliminates problems associated with leaking band-clamps while also reducing maintenance costs.
- Simul-Shift™ and Quick Dump™ valve technology for stall free and ice free operation
- Intelligent Design – Modular major valve design for easy repair and maintenance
- Built to Last – Convoluted diaphragms for long life
- Size – Available in 3″, 2″ and 1.5″ port sizes
