Wilden® Specialty Air Distribution System (ADS) for Air-Operated Double-Diaphragm (AODD) Pumps

The Wilden® Advanced™ Series High Pressure Air-Operated Double-Diaphragm (AODD) Metal Pumps are equipped with a specialty air distribution system (ADS) that utilizes a double acting power piston and duplex technology to intensify fluid discharge pressure. Wilden high pressure pumps reliably deliver the pressure performance to transfer viscous, solid-laden slurries.

When repairing or maintaining Wilden Air Distribution Systems (ADS), always use only authentic Wilden Air Kits to maintain optimal performance and preserve Wilden factory warranties.

This new Air Kit contains a reduced number of parts, eliminating the air valve assembly and muffler plate. All Air Kits now include the air valve spool and are available only in the Air Kit. They will not be sold separately. All Air Kits are vacuum-sealed to maintain parts integrity and cleanliness. Each Air Kit can be applied to many different models to significantly reduce the number of kits required to cover Wilden’s products and simplify ordering. See the Repair Kits Page for more information.

Wilden Specialty ADS are used on the following high pressure pumps:
