The GRACO A23559 is a chemical injection pump featuring an HNBR (Hydrogenated Nitrile) seal and a 1/2 inch plunger, designed for reliable and precise chemical dosing in industrial applications. It is constructed with robust materials for durability and is intended for use in systems requiring accurate chemical injection, such as lubrication, water treatment, or process control.

Key Features:

• Chemical Injection Pump
• G-Chem, 1/2 in Plunger, Duplex
• HNBR seal, 300 series stainless steel wetted parts (unless otherwise noted), UHMWPE and PTFE packing materials
• Compatible with a wide range of chemicals, provided they are compatible with HNBR, stainless steel, UHMWPE, and PTFE materials
• Easy to operate and maintain
• Reliable performance for continuous duty
• Robust construction for harsh environments
• Adjustable flow rate via cycle rate and stroke adjustment
• Low out-of-pocket cost compared to similar pumps

Applications:
Ideal for chemical injection applications in industries such as mining, agriculture, water treatment, and process control. Suitable for systems requiring precise and reliable chemical dosing.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and longevity of the equipment.
• Verify all system valves are open before priming the pump to avoid potential damage
• Follow the instructions provided with your calibration gauge for accurate flow rate adjustment
• Adjust the cycle rate and/or stroke adjustment to achieve the desired flow rate
• Repeat calibration and adjustment as necessary until the desired flow rate is achieved
• Consult the equipment manual for specific electrical and fluid connections
• Regularly inspect seals and wetted parts for wear or chemical compatibility issues
• Ensure all system components are within their maximum working pressure and temperature ratings
• Use only compatible fluids and solvents as specified in the manual
