The Fire-Ball® 425 Series is a high-volume grease pump designed for stationary, cover-mounted applications. It is constructed with a thick cast aluminum air motor housing and corrosion-resistant materials for durability. This pump is intended for demanding high-volume grease dispensing, especially in environments where multiple dispenses occur simultaneously.

Key Features:

• Grease pump
• Fire-Ball® 425 Series, 75:1 ratio, 400 lb. (181 kg) capacity
• Thick cast aluminum air motor housing, corrosion-resistant design with liquid salt nitriding, nickel plating, stainless steel, aluminum, and chrome on key components
• Designed for use with 400 lb. (181 kg) grease drums and compatible with GRACO stationary cover-mount systems
• Large air motor for high power and long pipe runs
• Fewer moving parts for reduced downtime and lower repair costs
• Non-metallic poppet valves for superior sealing, even in dirty air environments
• In-line pump design maximizes seal life by aligning air motor piston and fluid piston rods
• Corrosion-resistant for longer service life

Applications:
Ideal for high-volume grease dispensing in industrial, mining, agricultural, and vehicle service environments where multiple dispenses occur at the same time and long pipe runs are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems, reducing the risk of equipment failure and downtime.
• Ensure all equipment is turned off and follow the pressure relief procedure before installation or maintenance
• Check equipment daily for proper operation and signs of wear
• Install according to GRACO’s recommended procedures for stationary cover-mounted systems
• Use only compatible accessories and replacement parts
• Regularly inspect seals and valves for wear or contamination
• Follow manufacturer’s recommended maintenance schedule
• Use only authorized repair kits and replacement parts
