Pump and Tank Combinations


  • There is no 5 gal / 19.4 liter version because the flow rate of the G4 requires minimum 10 gal / 37.8 liter tank.

  • Dimensions may vary because of variations between motor manufacturers. If dimensions are critical, consult factory.

  • Dimensions do not include pump handle.

* For Quick Demountable (QC) motor option, add 7 15/32“ (190mm) to overall height.
