ARO 67400 Air Motor Assembly, 2 Inch

The ARO 67400 is a 2 inch air motor assembly for ARO piston pumps. On an air-driven piston pump, the air motor is the power end: compressed air drives a piston back and forth, and that motion is passed to the lower pump section that moves the fluid. Buying the motor as an assembly lets you replace the whole power end instead of rebuilding it piece by piece.

Our catalog gives the 2 inch size and the piston pump application, but no pump ratio or matching lower section. Read the model number from your pump nameplate and check that 67400 is the air motor named in that model's parts list.
