Shop All-Flo™ 1-1/2 Inch AODD Pumps
All-Flo™ 1-1/2" AODD pumps are sized for higher-flow transfer and process duty, typically delivering flow up to approximately 120 GPM depending on model, diaphragm, and air supply. Port size is the primary driver of a pump's flow capacity, so matching it to your line keeps velocity and efficiency in the right range.
