About Fountain Pumps
The “head” of a pump is an important term to know. Head means the vertical lift from the surface of the water to its outlet. If the surface of your water is five feet below the water feature’s outlet, then the pump’s head is five feet.
In most pump manufacturer’s specs, you will find maximum HEAD, along with a Pump Curve. This is the lift from the TOP of water, NOT the bottom of the reservoir, to the reservoir. For example, the Fountain Tech 650 has a maximum head of 140”. At zero feet it pumps 780 gallons per hour, at 20” of head it is pumping 680, at 60” it is pumping 580. This “curve” shows how many gallons per hour the pump is pumping at different water lifts.
