Compatibility and code verification

Match the complete pump model, generation, size, air distribution system, wetted material and elastomer before ordering. Similar-looking components may not be interchangeable.

Materials

Review the body, diaphragms, balls, seats, seals and process-fluid compatibility as a complete system. Do not approve a material from one component alone.

Performance

Part performance and service life depend on the correct pump generation, operating pressure, fluid compatibility, assembly condition and maintenance procedure.

Suitable operating duties

Typical duties include chemical transfer, process circulation, tank unloading, coatings, wastewater and solids-bearing fluids where an AODD pump is appropriate. Final suitability depends on the actual fluid, concentration, temperature and duty point.

Selection guidance

Provide the fluid name and concentration, temperature, viscosity, solids size, suction lift, required flow, discharge pressure, connection standard and available air pressure. For service parts, also provide the pump nameplate and the removed component code where visible.

Maintenance notes

Isolate and depressurize both air and fluid lines before service. Inspect diaphragms, valve balls, seats, seals, shaft and air-valve wear together. Follow the applicable WILDEN service manual for assembly sequence, lubrication and fastener torque.

DFIN TECHNICAL DECISION SUPPORT

A practical guide to 0.5

Use this page as a working product dossier: identify the item, review the duty, verify service relationships and prepare a complete enquiry.

Ask DFIN to verify this record

Identify the installed pump

Part 01-9804-55-204 should be checked against the full pump model, generation, serial number and existing component marking.

Confirm material and quantity

Similar service parts can differ by elastomer, polymer, metal grade, package quantity or pump revision. Confirm every field before ordering.

Review kit relationship

Determine whether this item is supplied individually, inside an Air End or Wet End kit, or as part of a larger assembly.

Prepare the maintenance record

Record the failure position, operating hours, fluid, pressure and photographs. This helps identify related wear items before the pump is returned to service.

How do I verify part 01-9804-55-204?

Use the complete item code together with the pump model, serial number, generation and material configuration. A photograph of the removed part is helpful, but appearance alone is not sufficient.

Is this part sold individually or in a kit?

The supply scope depends on the item record and pump revision. DFIN can check whether it is individual, included in an Air End or Wet End kit, or supplied as an assembly.

Can a similar-looking part be substituted?

Not without verification. Dimensions, material, elastomer grade, valve geometry and generation can differ even when the overall appearance is similar.

What information speeds up a parts quotation?

Send the part code, pump nameplate, required quantity, material, position in the assembly, reason for replacement and delivery destination.
