Overview

The ARO PD05R-ASS-STT-B is a Compact Series air-operated diaphragm pump with 1/2 in. NPTF fluid ports. Its fluid valves combine Teflon/PTFE balls with 316 stainless steel seats, and the diaphragms are PTFE with a Santoprene backer. Fasteners are stainless steel.

Rated flow is 13.0 gpm (49.2 lpm). The pump accepts air at up to 100 psi (6.9 bar) and can build the same 100 psi on the fluid side. It handles solids up to 3/32 in. and is listed at 71.1 dB.

On the nameplate, the ASS center code and the STT ending identify this build. The STT ending lines up with the 637427-TT service kit on its parts list. A ground kit assembly is also listed, for installations where the pump must be bonded to ground.
