P/N AF0409A51FF24-02 ARO 4-1/4" Air Motor 9:1 Ratio Carbon Steel AFX Series Pneumatic 2-Ball Piston Pump
The ARO AF0409A51FF24-02 is an AFX Series air-operated two-ball piston pump designed for fluid transfer and dispensing applications. Its carbon steel lower pump features a hard-chrome-plated carbon steel plunger with UHMW-PE upper and lower packings and is configured for use with 55-gallon containers.
The 9:1 ratio, double-acting two-ball design delivers material on both the up and down stroke and supports dependable transfer and dispensing of oils, paints, coatings, chemicals, and other compatible fluids. Its 4-1/4-inch air motor and 4-inch stroke provide a maximum recommended operating rate of 60 cycles per minute.
Application suitability should be confirmed based on the specific fluid, viscosity, temperature, chemical compatibility, pressure requirements, and operating conditions.
