PRODUCT OVERVIEW

Configuration overview

WILDEN P8/WWAPP/NES/NE/NE is an air-operated double-diaphragm pump configuration organized by DFIN for accurate identification, selection and quotation. The complete code should be used because it defines pump size, wetted construction, air system, elastomers, valve components and special options.

Model and configuration explanation

The full WILDEN configuration code identifies size, body and manifold construction, center section, air distribution system, diaphragms, balls, seats and special execution. Similar model families can use different internal parts.

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

Published maximum flow is a reference value. Actual capacity depends on air supply, discharge pressure, suction condition, viscosity, pipe losses and solids content.

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.

No official item-specific component list is verified for this configuration yet.

Kit contents and quantities can change by pump generation, material code, special option and revision. DFIN verifies the exact item number and BOM before quotation.

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 P8/WWAPP/NES/NE/NE

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

Confirm the complete build

Use item 08-0129 together with the full model, nameplate and serial number. The complete code controls pump size, wetted materials, air system, elastomers and valve components.

Check the real duty point

Maximum catalog values are not a selected operating point. Confirm required flow, discharge pressure, suction lift, viscosity, temperature, solids and available air pressure.

Review all wetted materials

Assess body, manifolds, diaphragms, balls, seats and seals as one fluid path. Concentration, temperature and cleaning method can change the recommended construction.

Plan the repair package

Match Air Kit, Wet Kit and component codes to the installed revision before shutdown. DFIN can prepare a cross-checked service-parts list from the item number.

Answers for identification, selection and service planning. For a confirmed quotation, DFIN checks the complete application and configuration.

Send your item number to DFIN →

How do I confirm WILDEN item 08-0129?

Send the item number, full model, serial number and a clear nameplate photograph. DFIN will compare the construction, air system, elastomers and connection details before quotation.

Are the maximum flow and pressure simultaneous?

Usually not. Maximum values define catalog boundaries. A usable operating point must be selected from the appropriate curve using the real air supply, back pressure and liquid properties.

How are Air Kit and Wet Kit codes matched?

The pump item number, generation, air system and elastomer configuration are checked together. Kit contents and quantities are confirmed for the installed revision before supply.

What should be included in an RFQ?

Provide quantity, fluid and concentration, temperature, viscosity, solids, required flow and pressure, suction condition, connection standard, available air pressure and delivery destination.
