The GRACO 226942 is a stainless steel, air-operated piston transfer pump designed for mounting on 55-gallon drums to efficiently transfer low viscosity fluids. It features polyethylene (PE) packing for enhanced durability and is intended for reliable, smooth liquid movement in industrial and maintenance settings.

Key Features:

• Air-Operated Piston Pump
• 226942
• Stainless steel body with polyethylene (PE) packing
• 4 gpm (gallons per minute)
• Maximum pressure: 100 psi; Maximum air supply pressure: 180 psi
• Designed for use with low viscosity fluids, including petroleum- and synthetic-based oils
• Stainless steel construction for corrosion resistance
• Polyethylene packing for durability
• Air-powered for smooth, reliable operation and low cost of operation
• 1:1 ratio for direct air-to-fluid pressure transfer
• Easy to mount on 55-gallon drum bungs
• Minimal maintenance due to robust design and fewer moving parts

Applications:
Ideal for transferring low viscosity fluids such as oils and lubricants in industrial, mining, agricultural, and maintenance environments. Commonly used for drum-to-drum or drum-to-machine fluid transfer.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Mount the pump securely on the bung of a 55-gallon drum
• Ensure proper air supply connection (1/4 in NPT inlet)
• Check all seals and connections for leaks before operation
• Regularly inspect and maintain PE packing for longevity
• Follow manufacturer guidelines for air pressure and flow rate limits
• Periodically inspect for wear and replace PE packing as needed
• Clean pump components after use to prevent contamination
• Store in a clean, dry environment when not in use
