The GRACO 223844 is a pneumatic piston pump designed for high-pressure fluid transfer applications. It features a robust construction, typically available in stainless steel or carbon steel, and is intended for use in demanding industrial environments where reliable, uniform, and easily controlled fluid delivery is required.

Key Features:

• Pneumatic piston pump
• Monark Pump, Series A, 15:1 ratio
• Stainless steel or carbon steel
• Maximum flow at 60 cycles/min: 0.75 gallon (2.8 liters)
• Max fluid working pressure: 2700 psi (18.5 MPa, 185 bar); Max air input pressure: 180 psi (1.25 MPa, 12.5 bar)
• Designed for use with compatible GRACO equipment and accessories
• Positive displacement, 2-ball piston design for uniform and easily controlled delivery
• Low maintenance air motor
• Reliable and durable for severe-duty applications
• Recommended speed for optimum pump life: 15–25 cycles/min (0.18 to 0.30 gpm, 0.7 to 1.14 liters/min)

Applications:
Ideal for high-pressure fluid transfer in industrial, mining, and agricultural settings where consistent and reliable pumping is essential.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Always relieve pressure before servicing or disassembling the pump
• Stop the pump at the bottom of the stroke for overnight shutdown to prevent fluid from drying on the displacement rod
• Flush the pump before the fluid dries on the displacement rod and relieve pressure after flushing
• Follow the Pressure Relief Procedure as outlined in the manual to reduce the risk of injury
• Regularly inspect and maintain the pump according to the manufacturer’s guidelines
• Use only recommended fluids and accessories
• Keep the pump clean and free from debris
