CDL Light Vertical Multistage Centrifugal Pump - Max inlet pressure & Max working pressure

Max inlet pressure
The maximum inlet pressure is shown in the table below. But the actual inlet
pressure plus the valve close pressure of the pump shall be lower than the max.
Allowable working pressure.

The following figure shows the limitation of pressure and temperature,
which shall be kept within the region as shown in the figure.

Performance curve
Following conditions are suitable for the performance curves shown bellow
1.All the performance curves are based on the measured values of a motor
3 380V~415V at a constant speed of 2900rpm.
2.Curve tolerance in conformity with ISO9906, appendix A.
0 2 3.Measurement is done with 20 c air-free water, kinematic viscosity of 1mm /sec.
4.The operation of pump shall refer to the performance region indicated by the
thickened curve to prevent overheating due to too small flow rate or overload
of motor due to too large flow rate.
