My ECM Giotto is now officially 1/3 horse power.
I've replaced the solenoid pump with the motor and ProCon rotary pump.
I still need to tune the pressure...
To get a feel for how fast the new pump flows...
I put an empty PF on the machine and placed a one oz shot glass under
it.
It was full in two seconds.
A few details:
To avoid buying a BSPP fitting, I made my own adapter - just put a
compression fitting on the 1/4" hose that attached to the original pump.
My water reservoir for now is a PUR water dispenser. I created a simple
adapter to attach to the dispenser.
I'm still tuning, but the machine is happy to sit and keep its boiler
full. I'm waiting until I put a gauge on the PF before I start pulling
shots.

Congrats! Just curious, were you able to use the reservoir space and do an
inboard or did you outboard mod?

It's outboard. I have a big motor. With a smaller motor, I could have =
probaby fit it inside the machine.
It's going to be a few days before I put a pressure gauge on it. I tried =
pulling a shot anyway, and it came out faster than I'd like - at the =
end, the boiler pressure went up a bit. I think I'll get a pressure =
gauge on it before I try again.
