The GRACO 563307 Modu-Flo® HLJ-25M is a hydraulic piston pump designed for reliable lubrication and fluid transfer in industrial applications. It is constructed with steel, copper, nitrile, and PTFE wetted parts, and is intended for use with oil or grease up to NLGI-2. This pump is engineered for integration into GRACO lubrication systems, providing consistent and efficient fluid delivery.

Key Features:

• Hydraulic piston pump
• HLJ-25M
• Steel, copper, nitrile, PTFE (wetted parts)
• 200–2,000 psi (13.8–138 bar) hydraulic pressure; maximum working pressure up to 6,600 psi (455 bar) for some configurations
• Oil or grease up to NLGI-2
• Modular system design for flexible configuration
• Easy to standardize components and reduce inventory
• Adjustable pump settings
• Double-acting operation
• Lube-to-hydraulic pressure ratio: 5.5:1
• Reliable and easy to maintain
• Designed for high-duty cycle applications

Applications:
Industrial lubrication systems, mining, agriculture, and other heavy-duty environments requiring consistent and reliable fluid delivery.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems.
• Follow manufacturer’s instructions for hydraulic pressure settings (200–2,000 psi recommended)
• Ensure compatibility with oil or grease up to NLGI-2
• Regularly inspect wetted parts for wear and replace as needed
• Do not exceed recommended duty cycles (e.g., 10 cycles per minute with grease, 3 seconds on, 3 seconds off)
• Consult the manual for detailed installation and maintenance procedures
