AODD Pumps for Industrial Fluid Transfer
Air-operated double diaphragm pumps use compressed air to move two diaphragms in an alternating cycle. Start selection with the fluid and operating point—not pump size alone.
Choose the construction
Compare bolted metal, bolted plastic and clamped plastic constructions against containment, corrosion, abrasion, cleaning and maintenance requirements.
Size for the real duty point
Required flow must be evaluated at the expected discharge pressure with viscosity, suction lift, line losses and solids considered. Catalogue maximum flow is not the expected production rate.
Confirm every wetted component
Body material alone does not establish compatibility. Review diaphragms, balls, seats, seals and manifolds for the process fluid and cleaning liquid.
