Efficiency is expressed in percentages on the right of the pump curve graph. The BEP is represented by the efficiency curve’s peak, with efficiency declining as the curve arcs away, either right or left, from the BEP. Knowing the efficiency percentage will also help calculate horsepower required for an application.
