The GRACO 224752 is a hydraulically-powered piston pump designed for reliable grease dispensing in demanding mobile and industrial applications. It is constructed from steel, copper, polyurethane, buna-N, and polyester elastomer, and is intended for use in on-road vehicles and off-road equipment.

Key Features:

• Hydraulic piston pump
• Dyna-Star 5:1, 400 lb (180 kg) grease drum compatible
• Steel, copper, polyurethane, buna-N, polyester elastomer
• Output per cycle: With No. 2 grease at 60 cpm free flow: 5 lb/min; at 3000 psi: 4 lb/min
• Maximum hydraulic fluid input pressure: 1500 psi (10 MPa, 102 bar); Maximum grease output pressure: 7500 psi (51 MPa, 517 bar)
• Grease (No. 2 grease specified for flow rates)
• Reliable, quiet, ice-free performance at maximum pressure and low flow rates
• Up to three times more energy efficient than comparable compressed-air systems
• Self-lubricating for long-life and dependable operation
• Ultra-quiet hydraulic motor
• GRACO's reciprocator piston minimizes change-over stalls
• No assembly required, fits in a standard 120 lb (55 kg) or 400 lb (180 kg) grease drum
• Lighter, more compact design than competition
• Easy to connect, low-pressure hydraulic input
• Fewer moving parts reduces pump wear and maintenance

Applications:
On-road vehicles, off-road equipment, bulk grease transfer, and automatic lubrication systems.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance.
• Adjust the flow control valve to limit hydraulic flow to no more than 3 gpm (11 lpm), which is approximately 60 cycles per minute
• Ensure hydraulic fluid temperature does not exceed 130°F (55°C)
• Connect to a standard grease drum for easy setup
• Follow manufacturer’s guidelines for hydraulic input and output connections
• Regularly inspect wetted parts for wear and replace as needed
• Monitor hydraulic fluid and grease for contamination
• Keep pump and connections clean to prevent blockages
• Consult manual for detailed maintenance schedules
