ARO air-operated double-diaphragm pumps move chemicals, slurries and fluids in plants across every industry, and Ingersoll Rand compressors and air tools run beside them. When a diaphragm ruptures or an air valve sticks, the transfer stops. ARO diaphragm and fluid section kits, air valve kits, complete AODD pumps, IR compressor service parts and air tool spares — sourced through established channels, DDP from Dubai and Spain. Active AODD supply history in the Gulf.

ARO — an Ingersoll Rand brand — is one of the most widely installed air-operated double-diaphragm (AODD) pump lines in the world. From compact 1/4-inch units dosing chemicals to 3-inch pumps transferring slurries, ARO pumps run in water treatment plants, chemical facilities, mines, paint shops and marine applications across the Gulf, Africa and Asia. Their virtue is simplicity — but diaphragms, balls, seats and air valves are consumables, and the correct repair kit depends entirely on the pump’s material configuration.
Meliora sources ARO pump parts and complete pumps with active recent AODD supply history for Gulf-region clients, alongside Ingersoll Rand compressor parts and air tool spares — DDP from Dubai and Spain with every wetted material option covered.
Every ARO pump carries a model code that specifies size, housing material and wetted materials — diaphragms, balls and seats. Send the full model code from the pump’s nameplate and we identify the exact fluid section and air valve kits without guesswork. If the plate is illegible, the pumped fluid, pump size and photographs are enough to confirm the correct materials — chemical compatibility of the diaphragm material with your fluid is the one decision that must be right.
An AODD rebuild takes an hour with the kit in hand — or weeks waiting for one to arrive. For plants running multiple ARO pumps, we quote fluid section and air valve kits per pump in shelf-stock quantities, consolidated into one DDP shipment. Diaphragm kits are compact, long-life stores items and the cheapest downtime insurance in the plant.
DDP from Dubai and Almería, Spain to the GCC, Africa, South Asia, Central Asia and worldwide.

Send the full model code from the pump nameplate — it encodes the size, housing material and wetted materials, which determine the exact fluid section and air valve kits. If the plate is illegible, tell us the pumped fluid and pump size and send photographs; we confirm the correct materials before quoting.
It depends on the pumped fluid: Santoprene for general abrasive service, PTFE for aggressive chemicals, nitrile for oils and fuels, EPDM for water-based and some chemical duties, Viton for solvents and elevated temperatures. Tell us the fluid and operating conditions and we recommend — chemical compatibility is the one decision that must be right.
Yes — metallic and non-metallic AODD pumps in all sizes for replacement or new duties, alongside fluid section kits, air valve kits and individual components. We quote repair versus replace so you can decide on clear numbers.
Stalling and icing usually trace to the air valve — worn seals or contaminated air supply. An air valve service kit restores operation in most cases; persistent icing also points to air supply moisture worth addressing. Describe the symptoms with your RFQ and we include the right kit scope.
