Table 66: Pump Curve Terminology (cont'd.)
Term
Description
Frequency/Speed
The pump speed (in RPM) or frequency (in Hz) for
which the pump curve is valid. Published pump
curves are valid at 60 Hz.
Head Curve
Illustrates the relationship between the fluid flow
through the pump and the head (amount of lift)
generated by the pump.
Operating Point
The flow rate, head, power, and efficiency at which
the pump is currently operating.
Operating Range
The range of flow over which the pump was
designed to run.
Power Curve
Illustrates the relationship between the fluid flow
through the pump and the power required by the
pump.
Pump Curve
Graph composed of the Head Curve, Power Curve,
and Efficiency Curve plotted against the fluid flow
through the pump.
Up Thrust
Condition in which the pump is operating at a flow
rate higher than the BEP. Note that some up thrust
is permitted within the operating range.
11.2 Apollo Pump Curve
The picture Figure 201: Apollo Pump Curve Labeled, page 244 shows the Apollo pump curve with each
part labeled.
