Graco Husky 1050 air-operated double diaphragm pumps have 1-inch (25.4 mm) porting connections and feature a stall-free, low-pulsation air valve for smooth, rapid changeover and minimised downtime. The pumps also come with a one-piece centre section, eliminating leaks and reducing maintenance compared to other diaphragm pumps. Husky 1050 is available in aluminum, polypropylene, conductive polypropylene, PVDF, stainless steel and Hastelloy construction to cover a wider variety of working fluids.

Graco air-operated double diaphragm (AODD) pumps use compressed air as a power source. The compressed air is shifted from one chamber and then to the other side by a linked shaft. This movement allows the chambrs to move simultaneously. This back-and-forth motion forces liquid out of one chamber and into the discharge piping while simultaneously filling the other chamber with liquid. These pumps use reciprocating elastomeric diaphragms and check valves to pump fluid. The liquid chambers are filled and emptied by fluid that is drawn through a common inlet and discharged through a single outlet.
