Graco Fire-Ball® 300 Series 50:1 35 or 70 lb (16 or 32 kg) Pail Grease Pump – Part No. 239877

The Graco Fire-Ball® 300 Series 50:1 Grease Pump (Part No. 239877) is renowned for its durability and efficiency. Designed for 35 or 70 lb (16 or 32 kg) pail applications, it delivers consistent performance in industrial settings. Its 3-inch differential air motor and double-acting pump design ensure reliable fluid flow and accurate dispensing. The thick cast aluminum air motor housing offers unmatched durability, while fewer moving parts mean less downtime and lower repair costs.

Furthermore, the in-line pump design aligns the air motor piston and fluid piston rods to maximize seal life. The displacement rods experience minimal wear due to Graco’s proprietary manufacturing process. Non-metallic poppet valves provide superior sealing, even in contaminated air environments. The large air porting design reduces icing and ensures continuous operation. Corrosion-resistant materials like liquid salt nitriding, nickel plating, stainless steel, aluminum, and chrome enhance longevity.
