How much water can I get with my

Typical domestic water application using tank for reservoir and for pressure to house.


Typical garden/irrigation application using both pumped water and discharged water. (Tanks not necessary.) 


Performance Chart for H74

To
determine water delivery using chart:

1  DETERMINE WORKING RATIO Divide Lift or Output Pressure by Fall or Inlet Pressure Note: 1 psi = 2.3 foot lift or fall 
Inlet Pressure: 50 psi (115foot fall) Output Pressure: 150 psi (345foot total lift) Working Ratio = 3:1 
2  EXPRESS WORKING RATIO AS A PERCENTAGE OF PUMP RATIO. Select a pump ratio. Divide Working Ratio by Pump Ratio. 
Try 4:1 
3  SEE CHART project a horizontal line from the Working Ratio percentage to appropriate Inlet Pressure curve. From this intersection, project a vertical line down to Inlet Flow. 
Inlet Flow 68 gpm 
4  CALCULATE OUTPUT FLOW: Divide Inlet Flow by Pump Ratio 
68 gpm ÷ 4 = 17 gpm
