PD05R-ASS-STT-B ARO 1/2" Stainless Steel Metallic Compact Series Air Operated Double Diaphragm Pump
P/N PD05R-ASS-STT-B ARO 1/2" Stainless Steel Metallic Compact Series Air Operated Double Diaphragm Pump
The ARO PD05R-ASS-STT-B is a metallic Compact Series 1/2-inch air-operated double-diaphragm pump designed for dependable fluid transfer in industrial and process applications. Its polypropylene center body with stainless-steel fluid caps and manifold, combined with PTFE diaphragms, PTFE check balls, and 316 stainless-steel seats, provides a durable fluid-handling configuration for a variety of applications.
The compact design is well suited for installations where space is limited, while the bolted, seal-less construction supports reliable pneumatic operation and convenient serviceability. This pump is well suited for fluid transfer, circulation, dispensing, and other applications where compact size, versatility, and ease of maintenance are important.
Application suitability should be confirmed based on the specific fluid, concentration, temperature, viscosity, chemical compatibility, solids content, and operating conditions.
