PRODUCT OVERVIEW
Configuration overview
WILDEN PX200/AAAAA/TNU/TF/ATF/0494 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.

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.
