Antlia AOD 150 — ½ Inch AODD Pump
The Antlia AOD 150 is a ½ inch Air Operated Double Diaphragm (AODD) pump built for reliable, chemical-safe fluid transfer in demanding industrial environments. Available in four body materials and two diaphragm options, it handles everything from aggressive acids to food-grade liquids.
Key Features
- Self-Priming: Automatically primes with up to 1.8 metres of suction lift — no manual priming needed
- Dry-Run Safe: Runs without fluid without damage — safe for intermittent or batch processes
- Explosion-Proof: Air-powered only — no electrical components, safe for flammable solvents and chemical zones
- Handles Solids: Passes solids up to 2.5 mm — suitable for slurries and viscous fluids
- Zero-Leak Design: Sealless construction — no mechanical seals to fail or leak
- Variable Flow: Adjust output by regulating air pressure (1–6 kg/cm²)
- Easy Maintenance: Modular design — replace diaphragms and valves without tools
How It Works
The AOD 150 uses compressed air fed through the ¼-inch air inlet. The air alternately pressurises two chambers, each with a flexible diaphragm. As one diaphragm pushes fluid out, the other draws fluid in — creating continuous, pulsating flow. Ball check valves ensure one-directional flow. No electricity required.
Material Selection Guide
- PP (Polypropylene): Acids, alkalis, water-based chemicals — most popular, lowest cost
- PVDF: Aggressive chemicals, chlorinated solvents, HF — highest chemical resistance
- SS 316: Food-grade, pharmaceutical, high-temperature applications
- Aluminium: General industrial use, non-corrosive fluids, compressed air systems
