Product Description

  Champion's R40A Pump is used on many of their top selling compressors, including the R-series and the popular Advantage Series of packaged air compressors. The R40A is rated for operation with 15 HP motors.

  The R40A is currently the standard factory-installed pump on the following models: HRA15-12, HRA15-25, BRA15, HRA15D-25



  1. Multi-finned Cylinders
    •  Provide cooler operating temperatures that result in longer life and consistent performance over time.
  2. Integral Cylinder/Head
    • Gasketless design of the compressor head eliminates the possibility of blown head gaskets for leak-free operation.
  3. Balanced Pistons
    • Aluminum alloy first-stage piston is weight matched to the cast iron second-stage piston, ensuring proper balance.
  4. Piston Rings
    • Featuring three compression rings and one oil control ring to provide excellent oil control, minimum blow-by and high efficiency air delivery.
  5. Lightweight Connection Rods
    • High-density, die-cast aluminum alloy connecting rods minimize reciprocating weight. An integral, precision-bored crankpin bearing and a needle bearing for the piston pin properly distribute bearing loads for longer bearing life than bushings.
  6. Pressure Relief Valves
    • Located in interstage and discharge allow safe and reliable operation.
  7. Intercoolers
    • Large-diameter finned tubing is positioned to obtain the greatest cooling effect between stages for maximum compressor efficiency.
  8. Optimized Cooling Fan/Flywheel
    • Precision balanced flywheel has fan blades for optimum compressor cooling and life.
  9. Reliable, High-Flow Valves
    • Single-unit, disc-type valves provide low lift and long life. Discs are made of corrosion resistant Swedish steel. Valves are easily serviced by removing the manifolds only.
  10. Oversized Main Bearings
    • Tapered roller-type main bearings provide full contact and support of the crank plus delivers the longest possible life.
  11. Balanced Crankshaft
    • Constructed of rugged ductile iron with large diameter throws for minimum bearing loads and counterweights to minimize vibration.
  12. Large Capacity Crankcase
    • Rugged cast iron oil reservoir has convenient sight gauge glass, corner oil fill boss and large oil drain.
  13. Loadless Starting
    • Positive acting, governor-type centrifugal unloader assures longer motor life by allowing the compressor to start unloaded every time.



  The revolutionary design of the Champion R-series pump utilizes a single cast head and cylinders so there is no head gasket to wear out. The one-of-a-kind Champion conical piston shape significantly reduces wear on the piston wrist-pin. The Champion R-series Pump found on every Advantage series and R-Series compressor uses a cast iron cylinder liner with aluminum cooling fins to increase surface area and allow the machine to run cooler. Champion disk valves are easy to service and provide the ultimate in durability. It is one of the most advanced and successful compressor pumps ever designed, and one of only two compressor pumps currently manufactured in the USA.
