ARO 637442-2 Service Kit, Inlet/Outlet, for PD03P Pumps
Inlet/outlet service kit in the -2 variant for ARO PD03P diaphragm pumps, PD03P-APS-PCC among them
Restore the suction and discharge side of an ARO PD03P pump with the 637442-2 kit. Four PD03P models list this -2 variant in their parts data.
For PD03P owners whose parts list calls for the -2 variant, ARO 637442-2 covers the inlet and outlet side of the pump. The catalog notes read only "Serv Kit, Inlet/Outlet", with no material or component list for this number.
The suction and discharge ports hold the one-way checks that turn diaphragm movement into steady flow. If they let fluid slip backward, each stroke delivers less than it should. Note the orientation of each part as it comes out so reassembly goes smoothly.
Symptoms This Kit Addresses
- Strokes sound uneven from one side of the pump to the other.
- Drips appear at the inlet or outlet port connections.
- Output has dropped after a long run of abrasive or heavy fluid.
Listed for These PD03P Pumps
Because the 637442 numbers differ only by suffix in our data, match your nameplate model to the parts list entry for -2 before ordering.
