ARO 637118-C services the air motor on PRO Series diaphragm pumps. It is listed for six 1" and 1-1/2" models in metallic and non-metallic builds.
WHERE TO BUY?
Unlike a fluid section kit, the ARO 637118-C targets the air side of PRO Series diaphragm pumps. The air motor directs compressed air to one diaphragm chamber and then the other, and its seals and sliding parts wear with run hours.
The listed pumps cover 1" non-metallic, 1" metallic and 1-1/2" metallic builds, and every model number ends in -C. Kit contents are not itemized in our product data, so compare the parts list for your pump with this part number before ordering.
Signs the Air Motor Needs Service
- The pump stalls or hesitates at the end of a stroke.
- Air blows by at the motor while the pump is running.
- Cycling turns erratic or slows at the same inlet air pressure.
