The FT30P is FTI Air's 3-inch non-metallic air-operated double diaphragm pump, launched March 2026: polypropylene wetted parts, 300 gpm at 120 psi inlet air, 0.5-inch solids, 28 ft wet suction lift, and a stainless-steel air valve with no separate pilot valve. At about 140 lb it is a high-flow chemical diaphragm pump that two people can still set on a skid.
Sizing an air operated diaphragm pump starts with the curve, not the max-flow number. Our free diaphragm pump sizing calculator places your flow and head on the FT30P curve. If a pump you already have stalls or won't prime, see diaphragm pump troubleshooting.

Frequently Asked Questions
Is Air-Operated Double Diaphragm (AODD) Pump compatible with Hydrocarbons/Fuels/Oils?
Moderate: Graco frames Husky generically as corrosion-resistant fluid paths for corrosive/abrasive chemicals and solvents rather than naming fuels/oils, so the family fit is by material rather than vendor claim. Two details worth publishing: conductive polypropylene on the Husky 1050 is the static-dissipating option that matters for flammable hydrocarbon transfer, and the Hastelloy Husky 1050 option is a genuinely new find from the Allied line card. QUANTM's EODD design stalls under pressure and cuts energy cost up to 80% vs pneumatic — relevant where a transfer duty runs continuously. Materials to confirm: Aluminum, Stainless steel, Cast iron (Husky 2150), Polypropylene and conductive polypropylene, PVDF, Acetal, Hastelloy (Husky 1050 — new detail from the Allied Fluid Products line card, not in the original Husky capture). Specific chemicals include mineral oil, lubricating oil, motor oil, diesel fuel, naphtha, solvent-borne adhesives and mastics.
