Determine required flow rate (GPM or L/min), discharge pressure, and air supply pressure. Match housing material to fluid compatibility — polypropylene for acids, PVDF for aggressive chemicals, stainless steel for sanitary or corrosive duty. Check ARO's performance curves for air consumption and stall points.

Are ARO air-end repair kits compatible across all ARO pump models?

No — repair kits are model-specific. Each ARO pump has a unique air-end assembly. Use the pump's model number and serial plate to select the correct kit. 3G Electric stocks genuine ARO air-end repair kits for double-diaphragm pumps, covering common aluminum, PP, PVDF, and stainless steel housings.

Can you source ARO pumps for worldwide delivery?

Yes. 3G Electric supplies ARO pumps and spare parts worldwide. We stock 405 ARO products and can source additional models on request. Provide your application details and we'll confirm availability and shipping lead times to your location.
