Pump Performance Curves
The pump performance curves shown in the illustrations below outline the maximum capability of the pump at
maximum speed of the pump. Following the installation guidelines will result in peak performance matching
the illustrated operation. Pump speed reduction will reduce the output capability.
The static pressure curve represents the pressure rise across the pump for a given flow. If the inlet pressure of
the pump is negative, the outlet pressure of the pump is reduced by the inlet suction. Be aware of this situation
in systems with little or no head pressure on the system.
