The GRACO 223595 is a reciprocating displacement pump constructed from carbon steel with chrome plating, designed for severe-duty applications. It is intended for use as a replacement or service part within GRACO’s Monark and President series pumps, handling a variety of fluids including high-solids coatings, resins, and cleaning fluids.

Key Features:

• Displacement pump, reciprocating
• Carbon steel with chrome plating, severe-duty
• Up to 2760 psi (190 bar, 19 MPa) maximum fluid working pressure (for associated 23:1 ratio Monark pump model 223596)
• Compatible with GRACO Monark and President series pumps, specifically designed for use with model 223596 (23:1 ratio)
• Severe-duty construction for abrasion resistance
• Stainless steel glands and intake housing (on associated pump models)
• Reliable, long-lasting performance
• Ease of maintenance with available repair kits

Applications:
Used in industrial and commercial fluid handling systems for transferring solventborne and waterborne fluids, high-solids coatings, resins, stains, lacquers, varnishes, cleaning fluids, and acid-catalyzed materials.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Follow the pressure relief procedure before servicing to prevent accidental startup.
• Ensure proper alignment and secure mounting of the displacement pump on the tie rods.
• Torque the packing nut/wet-cup to 18–20 ft-lb (24–27 N·m).
• Fill the wet-cup with GRACO Throat Seal Liquid or compatible solvent.
• Tighten tie rod locknuts evenly and torque to 10–15 ft-lb (14–20 N·m).
• Reconnect all hoses and ground wire after installation.
• Start the pump at about 40 psi (2.8 bar) air pressure to check operation.
• Regularly inspect and lubricate moving parts.
• Use only recommended repair kits (e.g., Repair Kit 235–636 for model 223595).
• Store hazardous fluids in approved containers and dispose according to regulations.
• Wear protective eyewear, gloves, clothing, and respirator as recommended.
