ARO PD30A-AAS-KTT-C 3 in EXP Metallic Diaphragm Pump
3 in metallic EXP AODD pump rated to 237 gpm and 3/8 in solids, with PTFE-faced diaphragms and PVDF seats
High-volume 3 in metallic EXP diaphragm pump with NPTF ports, PTFE/Santoprene diaphragms, PTFE balls and PVDF seats, moving up to 237 gpm.
For large transfer volumes, the PD30A-AAS-KTT-C is ARO's 3 in metallic double diaphragm pump from the EXP Series. It connects through 3 in NPTF ports and is assembled with stainless steel hardware. The fluid side uses two-piece PTFE/Santoprene diaphragms, PTFE balls and PVDF seats.
With up to 120 psi (8.3 bar) of air it can move 237 gpm (897.1 lpm), and the wide check valve path passes solids up to 3/8 in. Rated noise is 83.0 dB(A), so plan hearing protection or a muffled exhaust in enclosed areas.
