www.pumpfundamentals.comThe B.E.P. (best efficiency point) is the point of highest efficiency of the pump. All points to the right or left of the B.E.P have a lower efficiency (see Figure 4-4). The impeller is subject to axial and radial forces, which get greater the further away the operating point is from the B.E.P.
