Raja123 unless it’s 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 controller…. 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.
