Why the sim doesn't seems to respect the Centrifugal Pump Characteristics in Simscape (IL)?

Hello! I'm having a problem and i don't know exactly what is happening. I have the following simple system, where a centrifugal pump pumps water (from the isothermal liquid predefined properties block) into a pipe and back to the reservoir:

I'm using the default centrifugal pump characteristics for the Centrifugal Pump (IL) block, running at 1770 rpm. The pipe is a 100m 1 in² cross sectional pipe. I plugged both a gauge pressure sensor to the pump discharge and a flow sensor for the loop. When i run the system, i get crazy high results for the pressure and for the flow, like the follow:

750 lpm and 220 head pressure (m, converted from bar * 10) at steady state. I assumed the centrifugal pump would -cap- the flow at the block parameter "Maximum capacity at zero head", which is the default 80 lpm at 1770 rpm.

Am i wrong to assume this behavior? If so, what is the recommended way to cap the centrifugal pump to behave like the real one in that case?
