$145.53
Polyurethane diaphragm and ball repair kit for two ARO PD05 double diaphragm pumps, the PD05P-ARS-PUU-B and PD05R-ASS-SUU-B.
WHERE TO BUY?
The ARO 637427-UU repair kit is the polyurethane option for servicing the wetted side of two PD05 series double diaphragm pumps. Both the diaphragms and the check balls are listed as polyurethane, matching the UU code at the end of the part number and in each pump model it fits.
In an air-operated diaphragm pump, the diaphragms flex back and forth to move fluid while the check balls open and close against their seats to keep flow going one way. Replacing both together restores the sealing the pump depends on.
When to Use This Kit
- Fluid shows up at the air exhaust, a common sign of a split diaphragm.
- The pump struggles to prime or loses suction lift between strokes.
- Output drops even though air supply and stroke rate look normal.
Fits These ARO Pumps
One pump is a PD05P and the other a PD05R, so read the complete model code on your nameplate before ordering.
