The GRACO 237131 is a 1:1 ratio, air-operated stubby piston transfer pump designed for efficient transfer of low viscosity fluids. It is constructed with robust materials suitable for industrial environments and is intended for use in drum transfer or wall mount siphon feed applications within GRACO equipment.

Key Features:

• Air-operated piston transfer pump
• Stubby model, 1:1 ratio
• Available in stainless steel or carbon steel
• Up to 5 gpm (19 lpm)
• Maximum fluid working pressure up to 180 psi (12 bar, 1.2 MPa)
• Ideal for lower viscosity fluids such as antifreeze, asphalts, windshield washer fluid, motor oil, used oil, hydraulic fluid, oil, inks, and colorants
• UL options available when installed in accordance with NFPA; ETL listed for certain models
• Air-powered for high reliability and low cost
• Immersed inlet for faster priming of heavier fluids
• Disc check options for lower viscosity fluids
• Smooth, reliable flow
• Durable, long-lasting piston pump

Applications:
Commonly used for transferring low viscosity fluids in industrial, automotive, and manufacturing settings. Suitable for drum transfer or wall mount siphon feed applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Ensure proper torque settings for assembly (e.g., torque to 31–33 N•m as specified in manual)
• Lips of v-packings must face down; lips of packing must face up
• Follow all safety instructions and warnings in the manual before use
• For professional use only
• Regularly inspect and maintain seals and packings
• Use only recommended replacement parts
• Consult the manual for detailed maintenance procedures
