Air-operated double diaphragm pumps for precise, seal-less transfer of chemicals, slurries and shear-sensitive fluids — 100 to 300 LPM.

Chempro AODD Series pumps deliver precise flow control and reliable operation across demanding applications. Compressed air drives twin diaphragms — no motors, no seals, no glands — making them inherently safe for chemicals, solvents and solids-laden fluids.
Air-driven operation tolerates dry running and closed discharge without damage — a genuinely maintenance-free workhorse for transfer duty.
Wetted bodies in PP, PVDF, Stainless Steel or Aluminium with customisable diaphragm and seat options for chemical resistance.
