What the specifications mean
Rated flow (gpm)
Water delivery rate at the rated operating point.
Maximum head (ft)
The maximum vertical lift the pump can produce.
Must exceed your well's pumping water level plus pressure-tank pressure plus friction losses. Undersizing here is the most common well pump mistake.
Motor size (hp)
Nameplate motor horsepower.
