The GRACO 237129 is a 1:1 ratio air-operated piston transfer pump constructed from stainless steel, designed for reliable and efficient transfer of lower viscosity fluids such as oils, antifreeze, and hydraulic fluids. It is intended for use in drum transfer or wall mount siphon feed applications within GRACO equipment.

Key Features:

• Air-operated piston transfer pump
• 1:1 Ratio Fast-Flo, Stainless Steel Drum Pump with T Packing
• Stainless steel
• 4.0 GPM (as specified for this model; other Fast-Flo 1:1 models may reach up to 5 GPM)
• Up to 180 PSI (12 bar, 1.2 MPa)
• Lower viscosity fluids (e.g., antifreeze, motor oil, hydraulic fluid, inks, colorants)
• Air-powered for high reliability and low cost
• Immersed inlet for faster priming of heavier fluids
• In-line design with fewer parts to minimize pump wear
• T Packing for enhanced sealing and durability
• Durable, long-lasting piston pump

Applications:
Ideal for transferring lower viscosity fluids such as antifreeze, motor oil, used oil, hydraulic fluid, inks, and colorants. Suitable for drum transfer or wall mount siphon feed applications in service garages, manufacturing, and maintenance environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure the pump is installed according to GRACO guidelines for air pressure and fluid compatibility
• Use appropriate fittings and hoses rated for the intended fluid and pressure
• Regularly inspect and maintain T Packing and other seals to prevent leaks and ensure efficient operation
• Follow local safety regulations and NFPA guidelines if applicable
• Periodically check and replace T Packing as needed
• Inspect for wear and tear on moving parts
• Keep air supply clean and dry to prevent contamination
• Lubricate moving parts as recommended by GRACO
