ARO 66605J-3EB 1/2 in. Polypropylene AODD Pump | 13 GPM
ARO 66605J-3EB 1/2 in. polypropylene AODD pump features Santoprene diaphragms and balls, delivering up to 13 GPM at 100 psi.
ARO 66605J-3EB 1/2 Inch Polypropylene AODD Pump
The ARO 66605J-3EB is a compact 1/2-inch non-metallic air-operated double-diaphragm pump designed for dependable industrial fluid transfer. This configuration combines a polypropylene fluid section with Santoprene diaphragms and check balls for compatible process fluids.
The pump delivers flow rates up to 13 GPM (49.2 LPM) and operates at pressures up to 100 psi (6.9 bar). Its compact footprint, air-powered operation and serviceable construction make it suitable for OEM equipment, process skids and general industrial transfer applications.
Polypropylene Fluid Section
The 66605J-3EB uses polypropylene fluid caps, manifold and valve seats. Polypropylene offers useful corrosion resistance for many industrial liquids and chemical-transfer applications.
Always verify compatibility between the pump materials and the actual process fluid, including chemical concentration, temperature and any cleaning solution used in the system.
Santoprene Diaphragms and Check Balls
This configuration uses Santoprene diaphragms and Santoprene check balls. The elastomer components provide flexible diaphragm action and check-valve sealing for compatible fluids.
The complete model number is important because other 66605X pumps are available with different diaphragm, ball and seat materials.
Up to 13 GPM Flow
ARO specifies a maximum flow of approximately 13 GPM (49.2 LPM) for the 66605J-3EB.
Actual operating flow depends on air pressure, discharge pressure, fluid viscosity, suction conditions, piping restrictions and pump cycling rate. Use the applicable performance curve when sizing the pump for a specific duty point.
100 PSI Maximum Pressure
The pump is rated for a maximum air inlet and fluid discharge pressure of 100 psi (6.9 bar).
A properly sized air regulator and filter should be used to control the compressed-air supply and help protect the pneumatic section from contamination.
1/2 Inch Fluid Connections
The 66605J-3EB uses 1/2-inch NPTF fluid inlet and outlet connections with a one-piece manifold configuration.
The compact multiport design provides installation flexibility for industrial equipment and OEM systems. Confirm piping orientation and thread compatibility before installation.
Handles Solids up to 3/32 Inch
ARO specifies maximum solids handling of approximately 3/32 inch (2.4 mm). This allows the pump to transfer compatible liquids containing small suspended particles.
Particle concentration, abrasiveness, shape and fluid viscosity should also be considered when evaluating a solids-containing application.
Self-Priming Performance
Published specifications list a maximum dry suction lift of approximately 15 ft (4.5 m). Actual priming capability depends on fluid properties, suction piping, elevation, check-valve condition and operating speed.
Keeping suction piping short and properly sized can help improve priming and overall pump performance.
Compact and Serviceable Design
The ARO Compact Series is designed to provide useful pumping capacity in a relatively small package. Bolted construction supports controlled fluid-section sealing, while the modular pump design simplifies access during maintenance.
ARO also uses its unbalanced air-valve design in this pump family to support reliable cycling during pneumatic operation.
Service Kits
Documented service options for this configuration include:
- 637141 - Air Section Service Kit
- 637140-EB - Fluid Section Service Kit
The air and fluid service kits address different sections of the pump. Confirm the source of the maintenance issue before selecting replacement parts.
Application Considerations
The 66605J-3EB can be considered for compatible applications such as:
- General industrial liquid transfer
- OEM equipment
- Process and utility skids
- Compatible chemical transfer
- Recirculation and dispensing systems
Before purchase, confirm the required flow, discharge pressure, chemical compatibility, temperature, solids characteristics, suction conditions and available compressed-air supply.
