WHERE TO BUY?
ARO 637128-P44-B is catalogued as a kit assembly for marine pump equipment. The listing does not name its contents or materials. Compare the P44-B suffix with the kit number shown in your pump's service parts list to be sure it is the right one.
Within the parts data, this kit is tied to ARO piston pumps from the AF0813 and AF1020 model groups. Piston pumps rely on packings and seals around a moving rod, and these wear over time as the rod cycles.
When to Use This Kit
- The pump keeps cycling with the outlet shut, hinting at internal bypass.
- Material creeps out along the rod between strokes.
- Delivery falls off and stroke rate climbs at the same air setting.
