The GRACO 563365 is a pneumatic piston pump designed for in-plant machinery lubrication. It features a 3 lb. (1.36 kg) plastic cylindrical grease reservoir, a low level switch, and a pressure gauge. The pump body is constructed from aluminum and plastic, and it is intended for reliable, high-pressure grease delivery in industrial environments.

Key Features:

• Pneumatic Piston Pump
• E-Series, 3 lb. (1.36 kg) reservoir
• Aluminum (pump body), Plastic (reservoir)
• Maximum fluid output pressure: 2000 psi (138 bar); Maximum air inlet pressure: 150 psi (10.34 bar)
• Grease up to NLGI #2 or oil up to 30,000 cSt (SUS)
• Modular system design for flexible configurations
• Low level switch for reservoir monitoring
• Pressure gauge for system monitoring
• Easy to standardize components and reduce inventory
• Adjustable pump output (on adjustable models)
• High pressure rupture disc for safety (standard: 1750 psi / 121 bar)
• Reliable, entry-level alternative for pneumatic lubrication

Applications:
In-plant machinery lubrication, industrial environments requiring high-pressure grease or oil delivery, applications where space is at a premium and installation time is important.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure proper air supply (40–150 psi / 3–10 bar) is available
• Mount the pump securely in a clean, accessible location
• Connect the reservoir and verify low level switch functionality
• Use appropriate fittings and hoses rated for high pressure
• Test system for leaks and proper pressure before full operation
• Regularly inspect and maintain the pump and reservoir for optimal performance
• Follow manufacturer’s guidelines for installation and maintenance
• Use only compatible lubricants as specified
• Monitor pressure gauge and low level switch during operation
• Replace rupture disc if activated
