2.4 Pressure-Flow Curves
Figure 6: Pressure/flow curves for “High Flow” pump head for aqueous solutions
(Measured with pump-head LPP-2000.6)
The linearly increasing cavitation effects for the “High Flow” system for flows > 100 lpm and liquid
temperature range of 40 – 90
0
C was measured for water. This can be different for other liquids and depends
on the hydraulic circuit design. For example: higher inlet pressure reduces cavitation effects.
Figure 7: Pressure/flow curves for “High Pressure” pump head for aqueous solutions
(Measured with pump-head LPP-2000.7)
The linearly increasing cavitation effects between 75-85 °C for the “High Pressure” system have been
measured for water. This can be different for other liquids and depends on the hydraulic circuit design. For
example: higher inlet pressure reduces cavitation effects. For maximum static pressure limitation on
performance at temperatures > 70 °C consult specification under Figure 10.
