Product Overview
The ARO BP12SS-120-H is a pneumatically driven, double-diaphragm positive displacement pump engineered for demanding fluid transfer and metering duties in industrial hydraulic and process systems. Manufactured by ARO (Ingersoll Rand), this 1/2″ non-metallic series pump utilizes compressed air as its power source, reciprocating two flexible diaphragms connected by a common shaft to create a balanced, self-priming pumping action. Because it contains no rotating shafts, seals, or close-tolerance metal-to-metal wear surfaces, the BP12SS-120-H delivers reliable, leak-free performance with excellent dry-run capability and inherent deadhead protection. It is ideally suited for transferring corrosive, abrasive, viscous, or shear-sensitive media where conventional centrifugal or gear pumps would fail prematurely.

Engineering Features & Advantages
- Precision Performance: Balanced double-diaphragm design delivers smooth, pulsation-dampened flow with infinitely variable speed control via simple air regulator adjustment, enabling precise flow metering without complex VFD electronics.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a seal-less, gland-less construction that eliminates leakage paths and supports extended dry-run operation without damage.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring drop-in replacement for existing ARO BP12 series installations.
- Chemical Versatility: Stainless steel wetted path and non-metallic body components provide broad chemical compatibility for aggressive and corrosive media transfer.
- Self-Priming Capability: Draws suction lift from dry start, simplifying system commissioning and tank evacuation procedures.
Typical Industrial Applications
The ARO BP12SS-120-H is widely deployed across heavy industrial sectors including chemical processing and transfer of corrosive fluids, paint and coating circulation systems, wastewater and slurry handling in metallurgical plants, and fluid delivery on construction and marine hydraulic service equipment. Its air-driven, shear-sensitive operation also makes it a preferred choice for food and pharmaceutical batch transfer, ceramic slip handling, and CNC machine tool coolant management where reliable, contamination-free pumping is essential.
