Overview

Built around a 1/2 in. NPTF connection, the ARO PD05R-AAS-STT-B is an air-driven double diaphragm pump in the Compact Series. The AAS center code separates it from other STT builds in the family. The wetted valve set pairs 316 stainless steel seats with Teflon/PTFE balls, and each diaphragm is PTFE backed by Santoprene.

Expect up to 13.0 gpm (49.2 lpm) of flow, with air and fluid pressure each limited to 100 psi (6.9 bar). Particles up to 3/32 in. can pass. Hardware is stainless steel, and the noise figure is 71.1 dB.
