The GRACO 20A562 is a pneumatic (air-powered) grease pump designed for reliable, high-pressure grease delivery from 400 lb (180 kg) barrels. It is constructed for use with grease up to NLGI #2 and is intended for in-plant machinery, off-road equipment, and other industrial lubrication applications.

Key Features:

• Pneumatic piston pump
• Dyna-Star 120:1
• Robust metal construction for industrial environments
• Up to 12,000 psi (827 bar) maximum operating pressure
• Grease up to NLGI #2
• CE (for some models; not explicitly specified for 20A562, but likely similar to other Dyna-Star pumps)
• Easy-to-service design
• Reliable performance under high back pressure
• Suitable for continuous duty cycles in demanding environments
• Cover included for barrel protection

Applications:
In-plant machinery, off-road equipment, industrial lubrication, mining, agriculture, and other heavy-duty applications where high-pressure grease delivery is required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure proper air supply and pressure (typically 70 psi/4.8 bar for Dyna-Star pumps)
• Follow manufacturer guidelines for connecting to grease barrels and lubrication lines
• Regularly inspect and maintain seals and moving parts for long service life
• Use only compatible grease types (up to NLGI #2)
• Refer to the GRACO Dyna-Star instruction manual for detailed installation and maintenance procedures
• Schedule routine maintenance to prevent downtime
• Use only authorized repair kits and replacement parts
