ARO 637442-1 Inlet/Outlet Service Kit for ARO PD03P Pumps
The -1 inlet/outlet service kit in the ARO 637442 series, linked to four PD03P diaphragm pump models
ARO 637442-1 is the -1 inlet/outlet service kit for PD03P double diaphragm pumps. It appears in parts data for PD03P-BDS-DTT and three others.
ARO 637442-1 is the first suffix in the 637442 inlet/outlet kit series. Our records connect it to four ARO PD03P double diaphragm pumps. One of them, PD03P-APS-PAA, is described as a 3/8 in. non-metallic AODD pump. No materials or kit contents are recorded for -1.
Inlet/outlet service focuses on the passages where liquid is drawn in and pushed out. One-way checks there stop backflow, so the pump can build suction on one stroke and discharge on the next.
Time to Rebuild the Inlet/Outlet?
- Priming a dry line now takes several extra strokes.
- The pump will not hold a column of fluid once air is shut off.
- Flow readings have slid downward over several service intervals.
Where This Kit Fits
Other 637442 suffixes point to these same pumps. The kit number in your pump's own parts list, read with the nameplate model, decides which one you need.
