The GRACO 77X305 is an electric piston pump system designed for automatic lubrication of industrial machinery, off-road equipment, and on-road vehicles. It features a 90 lb (41 kg) grease reservoir, a follower plate, and a low-level sensor. The system is constructed for heavy-duty use in harsh environments and is intended to provide reliable, continuous lubrication to reduce equipment downtime and maintenance costs.

Key Features:

• Electric piston pump
• 77X305, 90 lb (41 kg) tank
• Heavy-duty, IP69K-rated enclosure; reservoir: steel, buna-n rubber wetted parts
• Maximum working pressure: 3500 psi (24.1 MPa, 241 bar) with vent valve installed; up to 5000 psi (34.4 MPa, 344 bar) without vent valve
• Single line parallel metering devices; compatible with oil to NLGI #2 grease
• IP69K (dust and water resistance)
• Low-level sensor alerts when lubricant is low
• Follower plate included for efficient grease dispensing
• Inline filter (400µm steel mesh)
• Remote fill manifold and auto-fill shutoff for spill-free, ground-level filling
• Reliable performance in harsh environments (-40°C to high ambient temperatures)
• Reduces unplanned downtime and maintenance costs
• Self-clearing low-level sensor (no follower plate required for sensor operation)

Applications:
In-plant machinery, off-road equipment, on-road vehicles requiring continuous, reliable automatic lubrication in harsh environments

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure proper grounding and electrical supply (24 VDC)
• Install in a location accessible for maintenance and refilling
• Use recommended lubricants and follow manufacturer guidelines for venting and filling
• Regularly check and service inline filter and low-level sensor
• Consult the manual for specific installation and maintenance procedures
