ARO PD05P-ARS-PUU-B Polyurethane Double Diaphragm Pump
1/2 in. Compact Series diaphragm pump: polyurethane diaphragms and balls in a polypropylene housing
This PUU version of the Compact Series 1/2 in. pump pairs polyurethane diaphragms and balls with polypropylene seats and housing.
Polyurethane is what sets the ARO PD05P-ARS-PUU-B apart. Both the diaphragms and the check balls use it, while the housing and seats are polypropylene. This 1/2 in. Compact Series pump runs on compressed air, has NPTF fluid ports, and uses stainless steel hardware.
Its rated output is 14.4 gpm (54.5 lpm). The maximum for both air inlet and fluid pressure is 100 psi (6.9 bar). Solid particles up to 3/32 in. can pass through the valves, and the listed noise level is 75.0 dB.
The PCC build of this pump uses Hytrel balls, while this model keeps polyurethane in both the flexing and the sealing positions. Choose it when your fluid suits polyurethane better, and check that in the chemical resistance guide first.
