The GRACO 563362 is a pneumatic pump designed for automatic lubrication systems, featuring a 4 pint (1.89 liter) plastic rectangular oil reservoir with a low level switch. It is constructed primarily from aluminum and plastic, and is intended for use in applications requiring reliable, compact, and easy-to-install oil lubrication solutions within GRACO equipment.

Key Features:

• Pneumatic pump for automatic lubrication
• E-Series, 4 pt. (1.89 liter) plastic rectangular oil reservoir, low level switch
• Aluminum pump body, plastic rectangular oil reservoir
• Fixed output: 0.030 in³ (0.491 cm³) per stroke; Adjustable output: 0.010–0.030 in³ (0.160–0.491 cm³) per stroke (note: this model is typically fixed output, but check specific configuration)
• Maximum rated operating pressure: 2,000 psi (138 bar); Standard high pressure rupture disc: 1,750 psi (121 bar)
• Oil up to 30,000 SUS or grease up to NLGI #2 (note: this model is specifically for oil reservoir, but pump can handle both types in other configurations)
• Compact design for space-constrained installations
• Low level switch for reservoir monitoring
• Easy maintenance and setup
• Reliable operation with high-pressure protection
• Can be used with or without a reservoir for flexibility

Applications:
Ideal for industrial, mining, construction, transportation, and agricultural equipment requiring automatic oil lubrication. Suitable for applications where price, installation time, and space are important considerations.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure proper alignment and secure mounting of the pump and reservoir
• Connect air supply within recommended pressure range (40–150 psi / 3–10 bar)
• Verify low level switch wiring and functionality before operation
• Regularly inspect and maintain the pump and reservoir for optimal performance
• Follow manufacturer’s guidelines for installation and maintenance
• Use only recommended lubricants and accessories
• Periodically check for leaks and wear
• Consult the manual for troubleshooting and part replacement
