The GRACO A23507 is a chemical injection pump designed for reliable and precise delivery of chemicals. It features an HNBR (Hydrogenated Nitrile) seal and a 1/4 inch plunger, constructed for durability and chemical resistance. This pump is intended for use in chemical injection applications within industrial and maintenance systems.

Key Features:

• Chemical injection pump
• G-Chem, 1/4 in Plunger, Simplex
• HNBR seal, 300 series stainless steel wetted parts (unless otherwise noted), UHMWPE and PTFE packing materials
• Designed for chemical injection systems; compatible with various accessories for integration into automated or solar-operated systems
• Easy access to pump plunger and packings for quick maintenance
• Plunger packings can be replaced in 10 minutes or less
• Robust and simple design with adjustable fluid packing for longer seal life
• Proprietary poppet style check valve to prevent valve sticking
• Same high-quality drive train as other GRACO chemical injection pumps
• Suitable for ordinary location environmental temperature range (-40° to 131°F / -40° to 55°C)
• Maximum sound pressure <70 dBa

Applications:
Ideal for chemical injection in industrial, mining, agricultural, and maintenance applications where precise and reliable chemical dosing is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems.
• Verify all system valves are open before priming the pump to avoid potential damage
• Follow the instructions provided with your calibration gauge for accurate chemical dosage
• Adjust cycle rate and/or stroke adjustment to achieve desired flow rate
• Repeat calibration and adjustment as necessary until the desired flow rate is achieved
• Refer to the equipment manual for electrical connections and environmental specifications
• Regularly inspect and replace plunger packings as needed
• Ensure all wetted parts are compatible with the chemicals being injected
• Keep pump and surrounding area clean to prevent contamination
