WILDEN APPLICATION GUIDE

WILDEN Pumps for Adhesives and Sealants

Sticky materials can form deposits on internal pump surfaces. The maintenance problem may be the way product builds up during stops rather than a simple shortage of discharge pressure. Describe skinning, curing and temperature sensitivity when requesting a pump recommendation.

Typical transfer duty

Compatible water-based and solvent-based adhesive formulations

Formulation tank → Viscous transfer → Packaging station

What to evaluate

Chem-Fuse integral piston diaphragms remove the conventional exposed outer-piston interface. Their availability and material compatibility must be checked against the exact WILDEN model and formulation.

Selection checklist

• Measure viscosity at transfer temperature

• Review curing and cleaning behaviour

• Check inlet conditions before increasing air pressure

Operating boundary

A diaphragm design does not make every adhesive pumpable. Reactive systems and heated duties require a separate review of temperature, materials and the operating procedure.

Maintenance and spare parts

Keep the complete WILDEN model code, installed diaphragm material and air distribution system in the maintenance record. Confirm air-kit and wet-kit compatibility separately. Follow the model-specific engineering, operation and maintenance manual for isolation, inspection, fastener torque and reassembly; a generic parts list is not a repair procedure.

Discuss your application

Send the fluid composition, concentration, temperature, viscosity, solids information, target flow, backpressure, suction conditions and available air supply. These details allow a meaningful configuration review and a matching spare-parts recommendation.
