AODD pumps with 1-1/2 inch (38.1 mm) connection available in polypropylene and PVDF

Request Info

Our new Husky 15120 pneumatic double diaphragm pumps have a single piece polypropylene center section for increased reliability and chemical compatibility, plus a patented, high-reliability modular air valve that is online serviceable. Design improvements include the overmolded frame which provides improved reliability and helps to eliminate fluid leakage and an updated diaphragm design that increases flow with flow rates up to 120 gpm (454 lpm) - making it one of the most efficient pumps on the market.

  • 1-1/2 in (38.1 mm) ANSI center and end-porting options available
  • High flow - 120 gpm (454 lpm) in a compact, portable size
  • Fluid pressure to 125 psi (8.6 bar, 0.86 MPa)
  • Lube-free operation
  • Available in polypropylene and PVDF
