The GRACO 224912 is a hydraulic piston pump designed for reliable, quiet, and efficient grease transfer. It is constructed from steel, copper, polyurethane, buna-N, and polyester elastomer wetted parts, and is intended for use in lubricating on-road vehicles and off-road equipment.

Key Features:

• Hydraulic Piston Pump
• 224912 (35 lb/16 kg pail size)
• Steel, copper, polyurethane, buna-N, polyester elastomer (wetted parts)
• With No. 2 grease at 60 cpm free flow: 5 lb/min (2.25 kg/min); at 3000 psi: 4 lb/min (1.8 kg/min)
• Maximum hydraulic fluid input pressure: 1500 psi (10.3 MPa, 103 bar); Maximum grease output pressure: 7500 psi (517 bar, 51 MPa)
• Grease
• Reliable, quiet, and ice-free performance
• Up to three times more energy efficient
• Maximum continuous cycle rate: 60 cycles per minute
• Maximum intermittent cycle rate: 60 cycles per minute
• Maximum working pressure: 1500 psi (10.3 MPa, 103 bar)
• Maximum suction lift: 13 ft (4 m)
• Sound pressure: 77 dB(A) at 66 cycles per minute

Applications:
On-road vehicles, off-road equipment, and other industrial lubrication applications where high-pressure, low-flow grease transfer is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment.
• Ensure hydraulic fluid inlet pressure does not exceed 1500 psi (10.3 MPa, 103 bar)
• Use compatible grease as specified
• Follow all safety and maintenance guidelines in the manual
• Regularly inspect wetted parts for wear and replace as necessary
• Regularly check for leaks and proper operation
• Clean and inspect the pump and associated components periodically
• Replace worn or damaged parts with genuine GRACO components
