ARO Pumpen 97284-2 Air-Operated Double Diaphragm Pump 2 Inch

Description

The ARO Pumpen 97284-2 air-operated double diaphragm (AODD) pump represents proven fluid handling technology engineered for continuous operation across diverse industrial applications. This 2-inch port size pump delivers dependable performance when transferring liquids ranging from low-viscosity solvents to medium-viscosity chemicals, coatings, and abrasive slurries. Built on decades of ARO pneumatic expertise, the 97284-2 model combines robust construction with operational versatility that maintenance teams and plant engineers demand. The air-driven design eliminates electrical hazards in volatile atmospheres while providing infinitely variable flow control through simple air pressure adjustment. With self-priming capability up to 6 meters of dry suction lift and the ability to run dry without damage, this diaphragm pump minimizes downtime and maximizes productivity in fluid transfer operations where reliability cannot be compromised.

The technical architecture of the ARO Pumpen 97284-2 centers on a balanced reciprocating diaphragm system that isolates pumped media from all moving mechanical components. Twin elastomeric diaphragms connect through a central shaft, creating alternating displacement chambers that deliver smooth, pulsation-dampened flow. The air distribution system employs a pilot-operated valve mechanism that precisely controls diaphragm cycling without external electronics, ensuring operational simplicity and field serviceability. Wetted materials are selected for broad chemical compatibility, with pump body construction typically available in aluminum, cast iron, stainless steel, or engineered thermoplastics depending on application requirements. Diaphragm and seat materials include options such as PTFE, Santoprene, Buna-N, and EPDM to match specific fluid characteristics. The 2-inch NPT or BSPT port configuration accommodates flow rates up to approximately 450 liters per minute at 7 bar air supply pressure, with maximum operating pressures reaching 8.4 bar depending on configuration. The pump’s displacement volume per cycle and air consumption characteristics optimize efficiency while maintaining consistent performance across varying system backpressures.

Industrial applications for the ARO Pumpen 97284-2 span sectors where safe, reliable fluid transfer is mission-critical. Chemical processing facilities deploy these AODD pumps for batch transfers, reactor charging, and process recirculation where corrosive or aggressive media challenge conventional pump technologies. Paint and coating manufacturers rely on the 97284-2 for metering and circulation applications where shear-sensitive formulations require gentle handling without product degradation. Mining and mineral processing operations utilize these pumps for transferring abrasive slurries, tailings, and process water where solid-laden fluids rapidly wear centrifugal pump components. Food and beverage processing plants implement ARO diaphragm pumps in CIP systems, ingredient transfer, and waste handling where sanitary design and dry-run tolerance prevent contamination and equipment damage. Wastewater treatment facilities deploy the 97284-2 for sludge transfer, chemical dosing, and effluent handling where submersible operation and self-priming capability provide operational advantages. Pharmaceutical manufacturing environments utilize these pumps for solvent recovery, API transfer, and clean-in-place applications where containment and material traceability are regulatory requirements. The petroleum and petrochemical sectors employ ARO AODD pumps for drum and IBC emptying, tank farm transfers, and loading operations where explosion-proof operation and spark-free design eliminate ignition sources.

The ARO Pumpen engineering advantage stems from continuous innovation in air motor efficiency, diaphragm materials science, and valve design optimization. Advanced air distribution valves reduce compressed air consumption by up to 40% compared to earlier generation designs, lowering operational costs while maintaining performance specifications. Proprietary diaphragm geometries extend flex life through stress distribution engineering that minimizes fatigue points and maximizes cycle longevity. Quick-release clamp systems enable field maintenance without specialized tools, reducing mean time to repair and minimizing spare parts inventory requirements. Non-stall air motor designs maintain consistent starting torque even under high backpressure conditions, eliminating the operational interruptions common in competitive products. The modular component architecture allows users to adapt pump materials and port configurations to evolving process requirements without complete equipment replacement. ARO’s global support network provides technical expertise, genuine replacement components, and application engineering assistance that extends equipment lifecycle and optimizes total cost of ownership. Third-party testing validates performance claims and material compatibility data, giving procurement managers confidence in specification compliance and operational reliability projections.
