ARO PD05R-BAS-PTT-B 1/2 in Compact Diaphragm Pump, BSP Ports
1/2 in Compact Series AODD pump with BSP ports, PTFE/Santoprene diaphragms, PTFE balls and polypropylene seats
Compact Series 1/2 in air-operated diaphragm pump with BSP connections, PTFE/Santoprene diaphragms and PTFE balls, delivering up to 13 gpm.
The PD05R-BAS-PTT-B is a 1/2 in double diaphragm pump in ARO's Compact Series. It runs on shop air and uses BSP-threaded inlet and outlet connections, which suits equipment built to British or ISO pipe threads. The diaphragms are PTFE/Santoprene: a PTFE face toward the fluid, backed by Santoprene. PTFE balls check the flow against polypropylene seats, and the hardware is stainless steel.
Output tops out at 13.0 gpm (49.2 lpm) with air at 100 psi (6.9 bar). The small 3/32 in solids rating points to clean or lightly loaded liquids, and the pump is quiet for its class at 71.1 dB.
