What is the Maths involved in Fixed Displacement Pump (Simscape- Hydraulics).

Hi all,

As in the figure, are the parameters for Fixed displacement pump. Nominal shaft angular velocity: 188 rad/s Nominal Pressure gain: 100e5 pascal.

In model, I am driving the pump using Ideal angular velocity source at 188 rad/s. I am expecting the pump pressure to be 100e5 pascal. But in actual, (sensed using hydraulic pressure sensor) its 5.29e7 pascal.

Can, anyone please, help me in finding what I am missing.

Thanks.
