The GRACO Modu-Flo® HLJ-5X Hydraulic Pump is a double-acting hydraulic pump designed for use in series progressive lubrication systems. It is constructed with steel, copper, nitrile, and PTFE wetted parts, and is intended to deliver oil or grease (up to NLGI-2) in industrial lubrication applications.

Key Features:

• Hydraulic double-acting pump
• HLJ-5X
• Steel, copper, nitrile, PTFE (wetted parts)
• Hydraulic pressure: 200–3000 psi (13.8–207 bar); Lube to hydraulic pressure ratio: 2.2:1
• Compatible with oil or grease up to NLGI-2; fits Modu-Flo pump-to-reservoir or remote wall mounting manifolds
• Double-acting operation
• Adjustable displacement
• Reliable for industrial lubrication
• Suitable for high-pressure environments
• Ease of maintenance (adjustable at the turn of a screw)

Applications:
Used in series progressive lubrication systems for industrial machinery, including mining, agriculture, and manufacturing, where reliable and high-pressure lubrication is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety in lubrication systems.
• Ensure hydraulic pressure is within the specified range (200–3000 psi)
• Use only compatible lubricants (oil or grease up to NLGI-2)
• Mount on Modu-Flo pump-to-reservoir or remote wall mounting manifolds as required
• Follow manufacturer’s guidelines for maintenance and adjustment
• Do not exceed recommended duty cycles (e.g., 10 cycles per minute with grease)
