P/N 637434 ARO® Air Section Service and Repair Kit
The ARO® 637434 Air Section Service and Repair Kit is designed for maintenance and repair of the air section of compatible ARO 2" and 3" metallic air-operated double-diaphragm pumps.
The kit provides replacement components used when servicing the pump's pilot and major valve systems, including applicable U-cup packings, O-rings, retaining rings, gaskets, and other air-section service components. A Lubriplate® FML-2 lubricant packet is also included for use during service and reassembly.
Please verify your complete pump model and air-section configuration before ordering to ensure compatibility. This is an air-section service and repair kit only and is not a complete air motor assembly or pump.
