Aro 637397 Air Motor Kit

The Aro 637397 Air Motor Kit is a replacement engine module designed for ARO diaphragm pumps used in recreational vehicles and light industrial systems. It fits the G0411695, G3431145, G2175101 and many other listed pump assemblies. Mechanics and RV owners who need to restore pump operation without replacing the entire unit will use this kit. It is not suited for buyers who require a complete pump assembly or a different drive configuration.

New condition and direct fit

Supplied new, the kit installs directly into compatible ARO PW10 and PD10 series pumps without modification. Normal operation draws only the compressed air the original design specifies, keeping thermal load and noise at factory levels. No additional lubrication or cooling provisions are required beyond what the host pump already provides. The unit adds no extra electrical demand because it is purely pneumatic.

Mounts inside existing pump housing

The motor kit mounts inside the existing pump housing using the original fasteners and seal surfaces, freeing bench space and eliminating the need for new plumbing or mounting brackets. It reuses the pump’s inlet and outlet ports, so no hose or fitting changes are necessary. Builders who need a different pressure ratio or flow curve will not find those adjustments in this kit.

Questions about this item

How do I install the 637397 air motor kit on my G0411695 pump, and which step is often missed?

Remove the pump from the system, disconnect air lines, separate the fluid section, swap the air motor assembly using the original fasteners, then re-pressurise slowly to check for leaks before full operation.

What maintenance will the 637397 kit need later, and which parts wear first?

The internal diaphragm and check-valve seats wear first; plan to inspect them at each fluid change and replace the soft goods if flow becomes erratic or air consumption rises.

What limit appears first when the 637397 kit runs continuously on a G3431145 pump?

The air motor’s internal seals heat up under sustained cycling, causing gradual pressure drop; allow cool-down periods or reduce cycle rate to maintain output.
