Fluid-O-Tech pump in EM6910 to lower flow rate/reduce pressure?
I know I'm over-obsessing about brew pressure, but just while it's on my mind, I'm curious to know how well a Fluid-O-Tech 1106 pump would go in the EM6910. The reason for asking is that I found this thread: The importance of brew pressure, purpose of adjusting OPV? - Espresso Machines • Home-Barista.com which mentions that this pump's pressure vs flow rate curve appears to be better suited to espresso, if an OPV is not present.
Would it be a drop-in replacement for the EP5?
Would there be any problems with the back flushing with this pump?
I've received advice here recently not to worry too much about brew pressure, and I am not ignoring this advice. I am just interested in the topic and am doing research whilst it's on my mind. (even that aforementioned thread mentions that temperature is more important)
It's not going to improve your coffee...
A coupla thou or so ought to be sufficient to purchase the the gear pump and motor from the Ambient Vesuvius as well as the 2 boards to operate it and the pressure control interface. Might be overkill on a sunbeam though
