Yamada AODD Diaphragm Pump

The Yamada AODD (Air-Operated Double-Diaphragm) pump is the workhorse for industrial fluid transfer where standard centrifugals fail: aggressive chemicals, high viscosity, abrasive slurry, shear-sensitive products, run-dry conditions, and intermittent duty.

Why AODD. No rotating seals to leak. No electrical motor near the fluid. Self-priming. Run-dry safe. Stalls under closed valve without damage. Inherent safety in flammable / explosive areas (no spark). Variable flow simply by throttling air supply. Ideal for chemical drum-emptying, ATEX zones, paint & pigment, food & beverage (sanitary), mining slurry, leachate recovery, and environmental remediation.

Material matrix. Pump body in aluminum, polypropylene (PP), PVDF, or stainless SS316. Diaphragm material in Santoprene, PTFE, Buna-N, Viton, or Hytrel based on chemical compatibility chart. Ball check valve and seat material matched to fluid abrasion. Selection driven by fluid type, temperature, pH, abrasive content, and regulatory compliance (FDA, USP Class VI, 3-A, ATEX).

Capability range. Capacity 25 to 1,000 L/min, head up to 80 m, particle size handling up to 12 mm (DP-F40 mining slurry model). NDP25 series for general transfer; DP-F-series for abrasive duty; FDA-compliant series for food / pharma. Air consumption typically 1-7 m³/min depending on size and duty point.
