The GRACO 258263 HP-50 Lubricator is a high-pressure, multi-pump lubrication system designed for dispensing non-corrosive and non-abrasive oils and synthetic-based lubricants. It is constructed for robust industrial use and is intended for integration into GRACO lubrication equipment to ensure reliable, automated lubrication in demanding environments.

Key Features:

• High-pressure lubricator
• HP-50
• Industrial-grade, with provisions for flange-mounted auto fill, low level in fill plate, and proximity switch
• Maximum pumping rate: 0.008 in³ (0.133 cc) per stroke (approx. 4 drops) at SAE 40 oil; Minimum pump rate: 0.001 in³ (0.017 cc) at max. pressure
• Maximum working pressure: 50,000 psi (344 MPa, 3,447 bar)
• Designed for use with non-corrosive and non-abrasive oils and synthetic-based lubricants
• 4 pumps for multi-point lubrication
• Low level in fill plate with proximity switch for automated monitoring
• Provisions for flange-mounted auto fill
• Reservoir capacity: 9 quarts (8.5 liters)
• Operating speed: 3 to 36 rpm
• Lubricant viscosity range: 100 to 5,000 SUS
• Operating temperature: -20°F to 120°F (-29°C to 49°C)
• Optional reservoir heating (steam or electric)

Applications:
Used in industrial settings requiring high-pressure, automated lubrication of machinery, including mining, manufacturing, and heavy equipment maintenance.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing GRACO equipment.
• Follow all safety warnings and instructions in the GRACO manual
• Ensure proper grounding and maintenance procedures are observed
• Install in a location accessible for maintenance and monitoring
• Use only compatible lubricants as specified
