The GRACO 226940 is a 1:1 ratio air-operated piston transfer pump constructed from carbon steel (with some stainless steel components) and designed for reliable, smooth transfer of fluids from drums or tanks. It is intended for use in industrial fluid transfer applications, especially where low viscosity fluids are handled.

Key Features:

• Air-Operated Piston Pump
• 226940
• Carbon Steel (pump body), Stainless Steel (some components), Leather Seal
• Maximum Flow Rate: 4 gpm (some sources list up to 5 gpm for similar models)
• Max Pressure: 100 psi; Max Air Supply Pressure: 180 psi
• Designed for drum transfer or wall mount siphon feed applications; suitable for lower viscosity fluids
• 1:1 ratio for smooth, reliable flow
• Air-powered for high reliability and low cost
• Immersed inlet for faster priming of heavier fluids
• Leather seal for durability
• Pump tube length: 34.6 in
• Outlet port size: 1-1/2 in NPT
• Disc check options available for lower viscosity fluids

Applications:
Ideal for transferring low viscosity fluids from drums or tanks in industrial settings. Commonly used in lubrication, maintenance, and fluid handling operations.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment and secure mounting for drum or wall mount applications
• Connect air supply according to manufacturer specifications (max 180 psi)
• Use compatible fittings and hoses for inlet and outlet connections
• Regularly inspect and maintain seals and moving parts for optimal performance
• Follow all safety guidelines and local regulations during installation and operation
• Regularly check and replace seals as needed
• Keep air supply clean and dry to prevent contamination
• Inspect pump body and tube for wear or corrosion
• Lubricate moving parts according to manufacturer recommendations
