The GRACO 279037 is a pneumatic piston pump designed for the low-volume transfer of petroleum and synthetic-based oils from 55-gallon (200L) drums. It features a steel tube construction and is engineered for reliability and ease of maintenance within GRACO equipment.

Key Features:

• Pneumatic Piston Pump
• Fast-Ball 100, 55 Gallon Drum, Steel Tube
• Steel tube, with wetted parts including zinc-plated carbon steel, aluminum, nitrile, polyurethane, nickel-plated aluminum, NBR, and polyvinyl chloride (for model 279037)
• Maximum fluid flow: 12.5 gpm (47.3 lpm); Continuous duty flow rate: up to 5 gpm (19 lpm)
• Maximum air and fluid working pressure: 150 psi (1.0 MPa, 10.3 bar); Air operating range: 40–150 psi (2.8–10.3 bar)
• Oil, gear lube, ATF (Automatic Transmission Fluid)
• In-line design with fewer parts for less pump wear
• Double-acting pump for reliable fluid flow
• Differential air motor for smooth operation
• Easy to install and service
• Redesigned for enhanced quality, durability, and reliability
• Recommended speed for optimum pump life: 90 cycles per minute and lower
• Maximum recommended pump speed: 170 cycles per minute
• Sound power level: 78 dB(A)

Applications:
Ideal for low-volume transfer of petroleum and synthetic-based oils, commonly used in industrial, mining, and agricultural settings for lubrication and maintenance tasks.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the pump within GRACO equipment.
• Ensure the pump is installed with the correct downtube length (34.5" for 55-gallon drums)
• Connect air supply within the recommended pressure range (40–150 psi)
• Use compatible fluids as specified (oil, gear lube, ATF)
• Regularly inspect and maintain wetted parts for longevity
• Follow manufacturer’s guidelines for maximum cycle rates and pressures to extend pump life
