ARO 95878 Ball (2" diameter) | Stainless steel Replacement Pump Part

ARO 95878 Ball (2" diameter)

The ARO 95878 is a diaphragm component intended for maintenance and repair of Diaphragm Pumps. It is selected by part number so maintenance teams can identify the correct replacement component without relying only on appearance or approximate dimensions.

This listing identifies the component as Ball (2" diameter) manufactured in Stainless steel. For reliable service, confirm the complete pump model, parts diagram and required quantity before placing an order.

Diaphragm Component for ARO Pump Service

The 95878 is used as a service replacement within its documented ARO assembly. Matching the exact part number is especially important when nearby components have similar shapes, sizes or materials.

Stainless steel Construction

The listed material for ARO 95878 is Stainless steel. Material identification matters because ARO pump configurations can use different elastomers, plastics or metals depending on the service location and model. Do not substitute a different material solely because the part appears dimensionally similar.

Documented Size or Connection Detail

The product description includes the dimensional or connection reference 2" diameter. Use this detail together with the ARO part number and pump model when checking replacement fit.

Compatibility and Model Verification

The product data associates ARO 95878 with Diaphragm Pumps. Compatibility can vary by pump size, construction code, revision and service configuration. Before ordering, compare the full model number and parts list rather than assuming that every pump in the same family uses the same component.

Maintenance Inspection

When the pump is opened for service, inspect the replacement area and related components for wear, deformation, corrosion, scoring, loose hardware or damaged sealing surfaces. Cleaning the mating area before installation can help prevent debris from affecting the new component.

• Verify the exact ARO part number.
• Confirm the complete pump model and assembly location.
• Check material and dimensional details where specified.
• Inspect neighboring seals, valve parts and hardware during service.
• Confirm the quantity required from the applicable parts diagram.

Ordering ARO Replacement Parts

For an accurate maintenance order, reference ARO 95878, the complete pump model and the service location of the part. Providing these details helps reduce ordering errors and makes it easier to determine whether the repair requires only this component or additional related parts.

ARO 95878 is a practical choice for planned pump maintenance when the documented component matches the existing assembly. Always follow the equipment service manual and site safety procedures when disassembling, inspecting and returning the pump to operation.
