Test Test Test Conditions: Conditions: Conditions: The pump was tested in water with
the inlet submerged. The air pressure was set at 100
psi (6.9 bar).
How How How to to to Use Use Use the the the Charts Charts Charts
1. Choose a flow rate and outlet pressure that falls
below the Power Limit Curve. Conditions outside
of the curve will decrease the life of the pump.
2. Set the VFD frequency corresponding to the
desired flow rate. Flow rates will increase with
outlet pressure lower than 10 psi (0.7 bar) and
with high inlet head pressure.
3. To prevent inlet cavitation erosion, the
Net
Positive Suction Head Available (NPSHa) of your
system should be above the
Net Positive Suction
Head Required (NPSHr)
line shown on the chart.
