Sample Performance Chart
The curves shown in Figure 1, Figure 2, and Figure 3 outline the typical performance capability of the oil pump
using a light weight oil. As can be seen, pump flow capacity increases with increasing pump speed. Power
consumption increases with increasing pump speed and increasing discharge pressure.
NOTE:
All current pump models have been optimized for use with lighter weight oils like ATF. Performance
will be reduced for heavier weight oils.
NOTE:
The sample performance charts (Figure 1 and Figure 2) were taken using automatic transmission
fluid (Dexron VI) heated to 25 °C and 100 °C, respectively, with an input voltage of 28 Vdc. Figure 3
illustrates the difference in flow versus power consumption between 25 °C and 100 °C temperature settings.
The actual performance of the pump will vary from application to application. The power required to pump
will increase as the oil temperature is reduced and/or for the use of heavier weight oils. Power consumption
will increase with increasing oil viscosity, and will decrease with decreasing oil viscosity. The integrated
motor drive controller will limit the current draw to a maximum of 25 amps. Because of this the maximum
power allowable will be voltage dependent. For example, using a 14V power supply will yield a maximum
pump power of 350 watts which is half that for a 28V power supply. The reduced power will also directly
impact performance at lower temperatures and for heavier weight oils.
