Understanding TDH
Total Dynamic Head is the head the pump must overcome to deliver water at the selected pressure.
Pumping water level + elevation change + (PSI × 2.31) + pipe friction + equipment losses + velocity head
Example: where 390 ft comes from
With a pumping water level of 250 ft and 60 PSI at the wellhead, the starting head is 250 + (60 × 2.31) = 388.6 ft. About 1.6 ft of pipe friction and 0.02 ft of velocity head bring it to approximately 390 ft. Friction depends on flow, pipe size, material and length.
Pump setting determines the drop-pipe length. Lift is measured from the water level while pumping, not from the pump intake or the well bottom.
Confirm well yield, installation clearances, motor requirements and current manufacturer specifications before selecting equipment.
