ARO 93947 "O" Ring | ARO Diaphragm Pumps Part for Service for Repair

ARO 93947 "O" Ring Replacement Part

The ARO 93947 "O" Ring is a replacement service component for compatible ARO / Ingersoll Rand equipment. It is intended for maintenance teams, repair technicians and operators who need to replace a worn, damaged or missing component while keeping the equipment configuration consistent with the applicable parts documentation.

Using the exact 93947 part number is important because ARO systems can contain visually similar components with different dimensions, materials or functions. Match the part number to the equipment model and exploded parts list before ordering.

Product Identification and Construction

The supplied product record does not state a specific construction material. Before ordering, compare the part number and the applicable equipment parts list rather than selecting a replacement by appearance alone.

The catalog record associates this part with Diaphragm Pumps. Use that application reference as a starting point, then confirm the complete equipment model and parts diagram before purchase.

Compatibility and Model Verification

Compatibility can vary between pump, ram, lift, finishing and fluid-handling configurations, even when components look similar. Confirm the complete model number before placing an order.

Do not assume interchangeability based only on the component name. ARO assemblies may be revised across model sizes, ratios, materials and mounting arrangements. The safest ordering method is to verify the complete equipment model, the required item position in the parts diagram and the manufacturer part number.

When to Replace the "O" Ring

Replacement may be appropriate when routine inspection shows physical damage, excessive wear, deformation, corrosion, looseness, leakage around the related assembly, loss of adjustment, or a service condition linked to this component. The exact symptoms depend on where the part is installed and the function of the surrounding assembly.

• Inspect the existing component for wear, scoring, cracks, bending or damaged threads where applicable.
• Check mating parts and fasteners so a new component is not installed into a damaged assembly.
• Compare dimensions and orientation with the removed part before final installation.
• Follow the equipment service manual for torque, lubrication and assembly instructions.

Maintenance and Installation Considerations

Before disassembly, isolate the equipment from air pressure, fluid pressure and any stored mechanical load. Clean the service area and keep removed hardware organized so the replacement can be installed in the correct sequence.

If the component works together with seals, gaskets, rods, valves, plates, followers, adapters or mounting hardware, inspect those related parts at the same time. Replacing one visibly worn item may not correct a broader service issue if adjacent components are also damaged.

Ordering the Correct ARO 93947 Part

For an accurate maintenance order, confirm the following information before purchase:

• Manufacturer: ARO / Ingersoll Rand
• Part number: 93947
• Part name: "O" Ring
• Application reference: Diaphragm Pumps
• Required quantity: Verify against the applicable parts diagram or bill of materials

Providing the exact ARO part number together with the full equipment model helps reduce ordering errors and makes it easier to distinguish this component from similar replacement parts used elsewhere in the product family.

Customer-Focused Service Planning

For planned maintenance, consider the condition of the complete assembly rather than the isolated part alone. If the equipment is already being taken out of service, checking related wear items can help reduce repeat downtime and avoid reopening the same assembly shortly after repair.

The ARO 93947 "O" Ring is best selected by part-number verification, model confirmation and a review of the surrounding service components. This approach supports a more reliable repair and helps maintenance teams order the correct ARO replacement component the first time.
