Double Diaphragm Drum Pump

A Double Diaphragm Drum Pump is a versatile, air-operated (pneumatic) pump designed for transferring liquids from drums, barrels, or containers. Unlike manual rotary pumps, it uses compressed air to move fluids, making it ideal for harsh chemicals, viscous liquids, and abrasive slurries.

Key Features of Double Diaphragm Drum Pumps (AODD Pumps)

✔ Air-Powered – Runs on compressed air (no electricity), making it explosion-proof for flammable liquids.
✔ Self-Priming – Can run dry without damage.
✔ Handles Viscous & Abrasive Fluids – Works with thick oils, paints, adhesives, and slurries.
✔ Chemical Resistance – Diaphragms available in Santoprene, PTFE, Nitrile, or Viton for acids, solvents, etc.
✔ Dry Run Capable – Won’t fail if the drum runs empty.
✔ Adjustable Flow – Controlled by air pressure (typically 3–8 GPM).

Common Uses

• Chemicals: Acids, solvents, caustics.

• Paints & Inks: High-viscosity fluids.

• Food & Pharma: Sanitary models available.

• Oils & Fuels: Diesel, lubricants, kerosene.

• Waste & Slurries: Abrasive or particle-laden liquids.

Things to Consider Before Buying

⚠ Air Supply Needed (typically 20–100 PSI).
⚠ Diaphragm Material – Must match your liquid (e.g., PTFE for acids).
⚠ Discharge Hose – Some models include one; others require separate purchase.
