The GRACO 562845 Injecto-Flo AO-1 is a positive displacement, single-stroke, air-operated pump designed for oil lubrication systems. It features a 4.2 pint plastic rectangular reservoir and is intended for use in automated lubrication applications, particularly with piston distributors for oil delivery in industrial settings.

Key Features:

• Air-operated (pneumatic), positive displacement, single-stroke pump
• AO-1, 4.2 pint plastic rectangular reservoir
• Plastic reservoir, metal pump body
• 0.80 in³ (13 cm³) per stroke
• Maximum working pressure: 450 psi (31 bar)
• Designed for use with piston distributors for oil lubrication; compatible with oils of 250–5,000 SUS viscosity
• Compact design for easy integration into various applications
• Built-in vent valve for fast setup with piston distributors—no additional kits required
• Remote-mounted 3-way air solenoid valve control (valve sold separately)
• Reliable, high-quality gear pump for trouble-free operation
• Short pump off time between cycles for higher output rates
• Modular system design for flexible configuration
• Easy to standardize components and reduce inventory

Applications:
Industrial oil lubrication systems, especially those using piston distributors for precise, automated lubrication of bearings and machinery components.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure air supply is filtered and regulated before connecting to the pump
• Install the remote-mounted 3-way air solenoid valve as specified for proper control
• Follow manufacturer guidelines for reservoir and pump mounting
• Regularly inspect and maintain the pump and reservoir for leaks or wear
• Use only compatible oils (250–5,000 SUS viscosity) as recommended
