The 1/2" mount holes in this pump are larger than normal, allowing it to be moved up or down slightly to help with belt tension.

  • Adjustable mounting holes
  • High flow and pressure rates
  • Adjustable cam stop
  • Extra-thick fan hub
  • 3/4" inch heavy duty bearing
  • Pressed-fit and set-screw-retained fan hub
