Genuine Wilden repair kits in stock — diaphragms, balls, seats and seals in one kit to fully service your pump. Fast worldwide shipping.
The efficient way to service a diaphragm pump is to do it once, properly — every wear part at the same time — rather than chase failures one at a time. That’s what a repair kit is for: the diaphragms, balls, seats and seals a given pump needs, bundled for a single planned overhaul.
We stock genuine Wilden repair kits matched to the model and wetted material, so you can schedule maintenance instead of reacting to a breakdown. Order the wet-end kit, the air-end kit, or both — and keep a spare on the shelf for the next service while you’re at it.
Tell us the pump model number and material and we’ll confirm the exact genuine kit.
Part: genuine wet-end / air-end repair kits by model, Fits: matched to Wilden model & material (flow / head / power not applicable — spare part)
