Ulka E5EX coffee machine pump, used in Espresso machines, made in Italy. ~Au$110 in Oz. It's a magnetic piston pump like the Aquamist. Looks like Da Bomb. Oh it takes 120 Vac or 240 Vac so you'll need a >50W inverter for it. |
So, you seem to have a lot of suggestions for parts. Maybe a writeup is in order? :D
|
Yes Jason, please combine the information to make sense to the nOObs.

That pump will only flow enough to meet my needs at 0 psi dude i would keep looking
there should be better stuff out there. At the pressure most WI systems are designed to run it would only flow about 200cc/min wich is notvery much watter and i would want alot more headroom for anything i ran idk maybe it is just me. |
How much pressure do you need?
|
Pretty sure most guys run their sureflo pumps between 75 and 100 psi.

Let's back up for a second, here.
I honestly thought this was a joke when it was first posted. I'm still considering it to be in the troll category, rather than a serious solution. Forget for a moment about flow rate and pressure, we're talking about having to build or install an inverter into the cars electrical system and run 120VAC wiring through the vehicle. Who here thinks this is a better / safer / more reliable solution than a simple 12Vdc ShurFlo pump? I mean, what are the supposed advantages of the expensive coffee maker pump? |
Only one I can think of is size but even though its smaller once you build the converter and mount it all up I bet it takes up the same amount of room as a well packaged sureflo.
|
With the price of the DO kit, why hassle with making one. I was going to build my WI system but its going to be cheaper just to buy one.
On the other hand, good job on taking the DIY initiative. |
yea, would be nice if we could get a smaller pump to preform worth a damm.
|
A lot of the sizing of these types of things are driven by the laws of physics. A reasonably priced (non-NASA space probe component costs) 12VDC, water/meth compatible pump that performs reliably like the shureflo pump... is going to be about the same size as a shureflo pump.
Higher voltage more or less means a smaller motor, but as said already, you need an inverter, which means more mass/volume/complexity. |

An inverter that can drive this pump can be bought for $20 and is about the size of a pack of playing cards.
