The GRACO 224345 is a pneumatic, positive displacement piston pump constructed from stainless steel with UHMWPE (Ultra High Molecular Weight Polyethylene) and neoprene packings. It is designed for reliable, uniform delivery of a wide range of fluids in industrial and manufacturing settings, including cleaning fluids, high-solid coatings, acid-catalyzed materials, resins, and plural component coatings.

Key Features:

• Pneumatic, positive displacement, 2-ball piston pump
• Monark 5:1, stubby length available
• Stainless steel with UHMWPE/neoprene packings
• Up to 2.5 gpm (9.46 lpm) at up to 600 psi (4.14 MPa, 41.4 bar)
• Maximum fluid pressure: 600 psi (4.14 MPa, 41.4 bar); Maximum working pressure: 5000 psi (35 MPa, 350 bar) for some models (check specific model for exact rating)
• Handles cleaning fluids, high-solid coatings, acid-catalyzed materials, resins, high-solid plural component coatings, solventborne and waterborne fluids, stains, lacquers, varnishes
• Air-powered for high reliability and low cost
• Positive displacement, 2-ball piston design for uniform and easily controlled delivery
• Ultra High Molecular Weight Polyethylene (UHMWPE) packings for extended pump life in abrasive fluids
• Fluid return stanchion for circulation back to the pump
• Drum and stubby length models for mounting and application flexibility

Applications:
Ideal for high production applications requiring consistent and controlled fluid delivery, including industrial cleaning, coating, and material transfer in manufacturing, mining, and agricultural environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the pump system.
• Ensure proper alignment and secure mounting of the pump
• Use recommended air inlet pressure (30–120 psi, 0.2–0.83 MPa, 2.0–8.3 bar)
• Check all connections for leaks before operation
• Follow manufacturer’s guidelines for fluid compatibility and maintenance intervals
• Regularly inspect packings and seals for wear and replace as needed
