Which ARO repair kit do you need? Start with the complete pump model and the section being serviced. Check the exact kit contents before ordering: a fluid kit, a seat-inclusive fluid kit and an air-section kit cover different repair scopes.
The easily missed component
Replacing the flexible components of a fluid section does not automatically replace its valve seats. ARO distinguishes standard fluid-section repair kits from enhanced kits that include seats. This distinction matters when a maintenance plan requires both the moving check element and its mating seat to be renewed.
Read the kit boundary
ARO’s published standard fluid-kit description includes diaphragms, check elements, manifold and connecting-rod seals, with supporting service items. It states that damaged check-ball seats must be purchased separately. The manufacturer also offers seat-inclusive fluid kits. Exact contents still depend on the selected kit.
An air-section service kit is a different package. ARO describes different service scope for EXP and PRO air sections; an EXP description should not be used as a contents list for a PRO kit.
| Package | Purpose | Check before release |
|---|---|---|
| Standard fluid kit | Service listed fluid-section parts | Seats may be separate |
| Fluid kit with seats | Include matched check seats | Verify exact kit contents |
| Air-section kit | Service the air distribution section | Distinguish EXP and PRO scope |
Use the published example without turning it into a universal rule
ARO gives PD10A-BAP-AAA with 637401-AAA as an example of a fluid kit with seats. This is a documented pairing example, not a recommendation for every PD10 pump. It illustrates why the complete configuration suffix matters.
For another configuration, use its parts list or the manufacturer’s kit lookup. Do not derive a kit number by copying a suffix into an unrelated kit family.
Build a scope-complete maintenance order
Use three lines in the work package: the chosen kit, components explicitly excluded from that kit, and components retained after inspection. This exposes omissions before equipment is opened.
For example, if seats are on the replacement list, a standard fluid kit alone is an incomplete scope unless compatible seats are separately included. Conversely, do not automatically add individual seats to a seat-inclusive kit. Count the components from the confirmed contents list to avoid buying the same items twice.

ARO repair-kit questions
Does a fluid repair kit include valve seats?
Not necessarily. Confirm the bill of materials for the exact kit number. If seats need replacement, specify compatible seats separately or verify a seat-inclusive kit; do not assume the word “complete” defines the contents.
Is an air kit interchangeable with a fluid kit?
No. They service different sections. Match the kit to the pump series, full configuration and intended work scope.
Can I order parts using only “PD10” or the port size?
That is not enough for a reliable match. Provide the full model code, nameplate photo and relevant manual or parts-list reference. Record any known modifications before confirming the order.
Prepare a model-matched enquiry
Keep the pump identification, requested kit number, included components and separately required parts together in your request. Use the perpustakaan teknis to locate supporting documentation, then send WILLEE the complete model and repair scope for review.
An itemized, model-matched kit request is more useful than a generic request for a complete repair kit.
