Genuine Wilden AODD Diaphragm Pumps & Spare PartsWilden Pump Maintenance — Simple Service Intervals
How to keep a Wilden AODD pump running for years — simple checks, wear parts and service intervals. From an authorized Wilden dealer.

Genuine Wilden air valve and pilot repair kits in stock — restore the air distribution system that drives the pump. Fast shipping, authorized dealer.
When a diaphragm pump starts stalling, hesitating or freezing up mid-stroke, nine times out of ten it isn’t the wet end — it’s the air distribution system. The air valve and pilot are what shuttle air from side to side, and over time they wear or ice up and the pump loses its rhythm.
A repair kit brings it back. We stock genuine Wilden air valve and pilot kits for the range, so a hesitating pump gets fixed rather than scrapped. Fitting the genuine kit matters here — the air section is a precision assembly, and look-alike parts often don’t shuttle cleanly, which is how you end up back where you started.
Tell us the pump model and we’ll confirm the right kit and get it moving.
