ARO

ARO AODD pumps offer diaphragms in materials such as PTFE with Santoprene backing, and check valves in PTFE, Hytrel, and polypropylene (PP). These material options allow the pumps to handle a range of fluids, from corrosive chemicals to abrasive slurries. The specific material selection depends on the pump model and application requirements, such as chemical compatibility and temperature limits. For example, the 66615B-344-C model uses PTFE check valves and PTFE diaphragms with Santoprene backing, while the 66607A-3C9-A uses Hytrel check valves and PP seats. Always verify material compatibility with your fluid's properties before selection.

ARO aluminum-housing AODD pumps, such as the 66607A-3C9-A, can achieve flow rates up to 33 gpm and maximum heads up to 270 feet. Larger models, like the 66615B-344-C with a 316 stainless steel body, offer flow rates up to 90 gpm and heads up to 275 feet. These specifications are based on standard operating conditions with water at 70°F. Actual performance varies with fluid viscosity, specific gravity, suction lift, and discharge pressure. Consult the pump's performance curve for your specific application to ensure proper sizing.

The ARO MaxAir series manual air control valves, such as the M252TM, are three-way, two-position valves with foot pedal actuation and detent operation. They feature three ports and are normally closed. The valve body is gray and designed for manual control of compressed air in industrial settings. These valves are part of a broader MaxAir line that includes various actuation types (e.g., hand lever, palm button) and port configurations. Operating pressure is typically up to 150 psi, and port sizes range from 1/8 in to 1/2 in NPT. The detent mechanism holds the valve in position until manually released.

The ARO PremAir series solenoid-operated inline air control valves, such as the P251SS-012-D, are available with a 12V DC coil and 1/8 in female NPT ports. This specific model is a three-way, two-position valve with spring return and non-locking operation. Other PremAir models offer different voltages (e.g., 24V DC, 120V AC) and port sizes up to 1/2 in NPT. The solenoid valves are designed for reliable on/off control of pneumatic actuators and cylinders in automated systems. Ensure the coil voltage matches your control system's power supply.

An ARO repair kit, such as the 637318-P4C, is designed for servicing lower pump assemblies. The kit typically includes replacement diaphragms, check valves, seals, and gaskets necessary to restore pump performance. The exact contents vary by pump model and kit part number. For the 637318-P4C, it is compatible with specific ARO lower pump models. Always reference the kit's compatibility list or consult the pump's service manual to ensure the correct kit is used. Regular replacement of these components extends pump life and maintains flow and pressure specifications.

The ARO swivel (MPN 635117) with a 1/2 in NPT connection is a component that allows rotational movement in fluid handling systems. It is used to reduce stress on hoses and piping by accommodating angular misalignment or movement during operation. This swivel is typically installed in the fluid line between the pump outlet and the discharge hose or pipe. It is suitable for use with ARO AODD pumps and other fluid transfer equipment where flexibility in connection orientation is needed. The NPT threads provide a standard, leak-resistant seal when properly installed with thread sealant.
