GRACO 239731 – Fire-Ball 425, 75 1 Pail Length Grease Pump, 35 lb, Steel, Stubby Length

GRACO 239731 – Fire-Ball 425 Series 75:1 35 lb. Container Pail Length Grease Pump, Steel, 100 PSI

The Fire-Ball 425 features a large air motor to supply the power you need for long pipe runs and higher-volume dispensing. An ideal choice for applications where multiple dispenses happen at the same time.

The Fire-Ball 425 is the pump of choice for your most demanding high volume applications.

Durable – Thick cast aluminum air motor housing offers unmatched durability.

Fewer Repairs – Fewer moving parts in the air motor assembly means less downtime and low repair cost.

Superior Sealing – Non-metallic poppet valves offer positive sealing performance, even with contaminated “dirty” air environments for long life without repair.

Extended Seal Life – In-line pump design aligns the air motor piston and fluid piston rods to maximize seal life.

Corrosion-Resistant – Corrosion-resistant design utilizes liquid salt nitriding, nickel plating, stainless steel, aluminum and chrome on key components for longer life.
