3" AODD Pump — High-Volume Air-Operated Double Diaphragm Pump
A 3-inch AODD pump delivers high-volume transfer to 680 L/min (180 GPM) — for tanker offloading, bulk chemical transfer, large slurry lines and high-throughput plant duty. Large ball-check passages handle sizeable solids while retaining the sealless, run-dry-safe advantages of the AODD principle.
3" AODD Pumps — Key Specifications

⚠️ 3-inch pumps require generous air supply (1.5-2.5 m³/min at full flow). Confirm compressed air capacity before selecting high-volume duty.
Applications
Diaphragm & Elastomer Options
Match the elastomer to your media — the diaphragm is the highest-wear component and its material must be compatible with the fluid.
