The GRACO 239729 is a pneumatic piston pump designed for high-volume dispensing of grease from 120 lb (55 kg) drums. It features a nitrile rubber seal and is intended for demanding applications requiring long pipe runs and multiple simultaneous dispenses within GRACO lubrication systems.

Key Features:

• Pneumatic Piston Pump
• Fire-Ball® 425 Series, 120 lb (55 kg) drum
• Cast aluminum air motor housing, corrosion-resistant components (liquid salt nitriding, nickel plating, stainless steel, aluminum, chrome)
• Maximum air input: 100 psi (0.7 MPa, 7 bar); Maximum working pressure: 7500 psi (for 75:1 model)
• For use with non-corrosive and non-abrasive greases and lubricants only
• Large air motor for high power and long pipe runs
• Fewer moving parts for reduced downtime and lower repair costs
• Non-metallic poppet valves for superior sealing in dirty air environments
• In-line pump design for extended seal life
• Corrosion-resistant construction for durability
• Wiper throat seal type
• Sound power level: 94.62 dB(A); Sound pressure level: 80.85 dB(A)

Applications:
Ideal for high-volume grease dispensing in industrial, mining, agricultural, and vehicle service environments where multiple dispenses occur simultaneously and long pipe runs are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment.
• Ensure air supply is clean and within specified pressure limits (max 100 psi)
• Use only with non-corrosive and non-abrasive greases and lubricants
• Regularly inspect and maintain seals and moving parts to extend pump life
• Refer to the product manual for detailed installation and maintenance procedures
• Follow manufacturer guidelines for installation and maintenance
• Use recommended repair kits (e.g., SKU:. 207385) for servicing
• Keep air motor and pump components clean and free from contaminants
