Raja123 unless itās just a limiting bypass valve and speed control?), but the Preinfusion pressure setting does alter the output volume (ACS quoted that also). Does the Evo 2 use the same pump ?
Sorry i may be wrong in assuming its the same control system as the Evo
Its sounding like rhe Vostok has a more sophisticated control system then.
I assumed it was a simple set point controllerā¦. No speed control etc
Pump on and off until set point reached. System pressure held by non return value.
Pressure is pretty much instantaneously on and off with the rotary pump.
