Adrianmsmith the only thing thatās throwing me off that part is Iām testing with no puck resistance in the system. Just measuring output volume at various pressure settings.
Looking at the curves here matches what Iām seeing:
With no or little pressure, the flow rate will be at the maximum shown for the rpm. Iām referencing this for chamber fill rate only, before the valve shuts the pump off. With no puck, the system will shut off at the resistance of the sleeve, but once the pump is set beyond that pressure, it provides a continuous flow, because the shutoff pressure isnāt reached. However, for what I think Iām seeing to be correct, ACS would also be adjusting the rpm with the Preinfusion pressure settings rather than just shutting the pump off at the limiter, and I do agree thereās no real need to change pump rpm unless youāre trying to reduce noise (assuming the PSU can handle the max current). That said, thereās a chance someone wanted a gentler fill rate to āpreserve puck integrityā, so the lower Preinfusion settings operate at lower flow rates. Maybe DaveC knows ā¦
