How to keep a Wilden AODD pump running for years — simple checks, wear parts and service intervals. From an authorized Wilden dealer.
One of the quiet pleasures of an air-operated diaphragm pump is how little it asks of you. No shaft seal to fuss over, no oil to change, no close tolerances to protect. Maintenance really comes down to the wear parts and a bit of attention.
The diaphragm is the main one — it flexes constantly and will eventually fatigue, so plan to replace it rather than wait for it to let go on shift. The balls and seats wear more slowly; a gradual drop in flow or prime is the tell. And the air valve occasionally wants a service kit if the pump starts hesitating.
Keep a repair kit on the shelf, change the diaphragm on a schedule that suits your duty, and one of these pumps will run for years. Tell us your model and duty and we’ll suggest a sensible interval and the genuine parts to keep on hand.
