The GRACO Fire-Ball® 425 Series 50:1 400 lb. (181 kg) Grease Pump is a stationary supply package designed for high-volume grease dispensing. It features a robust cast aluminum air motor housing and is intended for use in demanding environments where multiple grease dispensers operate simultaneously. The pump is engineered for long pipe runs and high-volume applications, making it suitable for industrial and commercial lubrication systems.

Key Features:

• Grease pump
• Fire-Ball® 425 Series 50:1, 400 lb. (181 kg)
• Thick cast aluminum air motor housing, corrosion-resistant components (liquid salt nitriding, nickel plating, stainless steel, aluminum, chrome)
• Maximum working pressure: 7500 psi (51.7 MPa, 517 bar); Maximum air input pressure: 150 psi (1.0 MPa, 10 bar)
• For pumping non-corrosive and non-abrasive greases and lubricants only
• Large air motor for power in long pipe runs and high-volume dispensing
• Fewer moving parts for less downtime and lower repair costs
• Non-metallic poppet valves for superior sealing, even in dirty air environments
• In-line pump design maximizes seal life
• Corrosion-resistant construction for longer service life

Applications:
Ideal for high-volume grease dispensing in industrial, commercial, and vehicle service environments where multiple dispensers operate at the same time. Suitable for long pipe runs and demanding lubrication applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Install a bleed-type master air valve within easy reach of the pump, upstream from the air regulator
• Install an air filter to remove harmful dirt and contaminants from the air supply
• Follow all safety instructions and warnings in the product manual
• Ensure the pump is used only for non-corrosive and non-abrasive greases and lubricants
• Regularly inspect and maintain air filters and valves
• Check for leaks and wear on seals and moving parts
• Use only recommended lubricants and replacement parts
