The ARO PD01P-HKS-KTT-A is a 1/4" air-operated double-diaphragm (AODD) pump from ARO's compact 1/4" non-metallic series — self-priming, run-dry capable, and rated to about 5.3 GPM on compressed air up to 125 psi.
This build pairs Kynar PVDF fluid caps and manifold with Kynar PVDF seats, PTFE check balls and PTFE / Santoprene diaphragms. PTFE gives the broadest chemical compatibility in the line — the build to reach for with corrosive acids, caustics and solvents that attack rubber elastomers. Bolted construction keeps the fluid path leak-tight, and ARO's patented unbalanced air valve is designed to resist stalling and ice-up.
It suits dosing, metering, chemical feed and low-volume transfer where space and air supply are limited. Not sure this build suits your fluid? Send us your application details and we'll point you to the right part number.
