Graco Fire-Ball 425 Oil Pump 10:1 (Wall-Mounted Complete Unit) – High Delivery Performance for Long Lines & Parallel Dispensing Points

Fire-Ball 425 – air-operated piston pump for oil transfer with a 10:1 ratio. The wall-mounted complete unit is designed for long piping runs and higher output volumes – ideal when multiple dispensing operations occur simultaneously.

The Fire-Ball 425 operates with a 4.25" (107.9 mm) air motor and delivers the performance you need for demanding oil supply and distribution applications. Built for durability, easy to service, and designed for a long service life – especially in workshop and industrial environments with high dispensing frequency.

  • 4.25" air motor – strong performance for long lines & high output volumes
  • Robust casting – extremely durable die-cast aluminum air motor housing
  • Reduced downtime – fewer moving parts in the air motor = fewer repairs
  • Excellent sealing – plastic poppet valves provide reliable sealing even with “dirty” air
  • Corrosion-resistant – long-lasting components thanks to nitriding, nickel/chrome plating, and stainless steel/aluminum

Details & Information

Product Features
  • Air-operated oil pump (piston pump system) for stationary oil supply/distribution
  • Ratio: 10:1
  • Max. air inlet pressure: 180 psi (approx. 12.4 bar)
  • Max. working pressure (fluid): 1800 psi (approx. 124 bar)
  • Max. flow rate: 4.1 gpm at 80 double strokes/min (≈ 15.5 l/min)
  • Fluids: Oil
  • Connections: Air 1/2" NPT (female), Fluid inlet 1-1/2" NPT, Fluid outlet 3/4" NPT
  • Inline design (aligned air motor piston & fluid piston) – for extended seal life
  • Pump weight: 38 lb (≈ 17.2 kg)
Practical advantage: Stable oil flow even with parallel dispensing points – ensuring high process reliability over long piping distances.
Variants Overview – Configurations & System Setup

The Fire-Ball 425 is available in different configurations (e.g., as a pump only or as a complete system). This product is the wall-mounted complete unit in the 10:1 version – designed for higher volumes and simultaneous dispensing.

Version Typical Benefit
Wall-mounted complete unit (10:1) Fixed installation, clean distribution via piping, ideal for multiple dispensing points
Pump (without system components) Flexible integration into existing fluid management systems
Note: The suitable version depends on factors such as line length, number of simultaneous dispensing points, required flow rate, and installation concept.
Setup & Commissioning (Checklist)

For stable and long-lasting operation of the wall-mounted Fire-Ball 425 system, we recommend:

  • Install air preparation (filter/regulator) – protects valves and ensures smooth operation
  • Use shut-off valves on air and fluid lines – for safe maintenance/service shutdown
  • Properly size piping – minimizes pressure loss in long pipe runs
  • Define pressure settings carefully – observe max. 180 psi air / 1800 psi fluid pressure
  • Perform venting & priming correctly – ensures consistent flow from startup
Tip: With multiple simultaneous dispensing points, proper line planning (short runs, appropriate diameters) stabilizes flow and reduces pressure drop.
Intended Use / Applications
  • Oil supply in workshops & service areas
  • Fleet maintenance with multiple dispensing points
  • Industrial & manufacturing facilities with high dispensing frequency
  • Centralized oil distribution via long piping networks
