ARO EXP air diaphragm pumps feature the exclusive D-Valve system which prevents diaphragm stalling and air blow-by, thus ensuring consistent performance and reduced downtime. The ceramic sealing enhances durability, offering superior resistance to wear and chemical degradation, while optimising air consumption.

The SimulShift™ valve ensures smooth trip-overs, reduced pulsation and maintains laminar flow, making these pumps ideal for handling viscous or foaming liquids while delivering consistent flow.

All 1/4″ to 2″ non-metallic ARO PD pumps are upgradeable for solenoid operation, stroke monitoring and also leak detection. By replacing two plugs with proximity sensors or leak detectors, these pumps can be integrated with the ARO controller, thereby delivering process control along with real-time monitoring.
