The GRACO 247443 is a hydraulically-powered piston pump designed for reliable, long-life operation in demanding off-road mobile applications. It is constructed for use with grease and is intended to provide continuous, high-pressure lubrication to critical equipment components, preventing wear and failure.

Key Features:

• Hydraulic Piston Pump
• Dyna-Star, 120 lb (55 kg) reservoir
• Heavy-duty, engineered for off-road environments
• Maximum working pressure: 7500 psi
• Compatible with grease (maximum NLGI Grade #2, minimum cST 40)
• IP69K (Ingress Protection rating for dust and water resistance)
• Self-lubricating for long life and dependable operation
• Ultra-quiet hydraulic motor
• Reciprocator piston minimizes change-over stalls
• No assembly required, fits in a standard 120 lb (55 kg) grease drum
• Lighter, more compact design than competition
• Easy to connect, low-pressure hydraulic input
• Up to three times more energy efficient than comparable compressed-air systems
• Fewer moving parts reduces pump wear and maintenance

Applications:
Off-road equipment, including construction, mining, and agricultural machinery, where reliable, high-pressure lubrication is required to prevent component failure and extend equipment life.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems, minimizing downtime and repair delays.
• Ensure hydraulic input is connected to a low-pressure source as specified
• Install in a standard 120 lb (55 kg) grease drum for easy setup
• Follow manufacturer guidelines for pressure and flow settings
• Regular preventative maintenance is recommended for peak performance and longevity
• Consult the equipment manual or a GRACO specialist for detailed installation and maintenance procedures
