ARO 637442-5 Inlet/Outlet Service Kit for PD03P Pumps
Inlet/outlet service kit (-5 variant) listed for four ARO PD03P double diaphragm pumps
ARO 637442-5 services the inlet and outlet side of PD03P diaphragm pumps. Our data links it to four models, from PD03P-APS-PAA to PD03P-APS-0JA.
ARO 637442-5 is the -5 version of the 637442 inlet/outlet service kit. It is listed for ARO PD03P double diaphragm pumps, a range that includes the 3/8 in. non-metallic PD03P-APS-PAA. The catalog entry does not state materials or contents for this suffix.
On an air-operated diaphragm pump, the inlet and outlet are where fluid enters and leaves the chambers through one-way checks. Service at this point restores clean, single-direction flow. No manual is attached to this listing, so follow the PD03P pump manual for teardown steps.
When to Reach for 637442-5
- The pump takes longer than usual to prime.
- Fluid drains back into the supply when the pump stops.
- Discharge flow pulses harder than it did when new.
