Advantages of Wilden AODD Pumps




At Wilden®, reliable is in our DNA – we don’t cut corners just to save you money on the front end. Our air-operated double-diaphragm (AODD) pumps take reliability to the next level, combining design simplicity with rugged durability that end users have come to depend on for more than 65 years. That’s why our solutions are always a step above the competition.




The faster that pump parts wear, the more inventory you have to keep on hand and the more frequently your pump is in maintenance and out of production. Product changeovers can also create issues, requiring dismantling and cleaning of individual parts to prevent product contamination.


Wilden Solution

Chem-Fuse diaphragms, with an integral piston design, significantly extend the life of AODD pumps by eliminating outer-piston abrasion, especially when pumping abrasive fluids. Use Chem-Fuse to keep your pump in production longer, reduce parts inventory and enjoy easy cleanability for faster changeovers between product.




AODD pumps can stall, and some are even designed to stall as they feature a reset button. These pumps, especially when installed in an area that is hard to get to or monitor, could threaten to stop production by stalling.


Wilden Solution

Wilden’s Pro-Flo SHIFT and Pro-Flo air distribution systems (ADS) are designed with a non-stalling, unbalanced spool so that your AODD pump never stalls. Don’t halt production to restart, reset or even hit your AODD pump to get it moving again. Time, gallons of product and money are at stake.




To cut costs, other AODD manufacturers use aluminum, PTFE-coated aluminum or plastic for the center sections of their stainless-steel pumps. During a diaphragm rupture, if the product gets into the center section, it has the potential to corrode and destroy the pump, cause product contamination and create a safety hazard.


Wilden Solution

We take chemical compatibility seriously. When applications require it, Wilden provides a stainless-steel threaded or flanged bolted pump that has all stainless-steel components, including the air chamber and air distribution system. Reduce the wasted product, save on maintenance and cleanup cost and eliminate safety hazards with a chemically compatible pump.
