Re: Rancilio S10
can someone please explain this device to me? On the left is where the water enters from the pump. The two copper pipes at the top go to the bottom of the boiler (the return from the groups) and the one tube on the right goes to the inlet valve. What does the needle valve tap do? Is there a one way valve here somewhere?

Re: Rancilio S10
I ended up removing the whole group head, drilled through the gasket with a pilot and then 6mm drill. This allowed me to prise up the gasket and then clean the mating surface with a couple of nice sharp screwdrivers. I then cleaned it all up using some fine steel wool. Looking good now and ready for new gaskets. Incidently there was no group spacer under the rubber gasket!?
Thanks for all your help everyone. CS is a great place for great help.

Unfortunately Ralph,Originally posted by Ralph link=1190287064/0#11 date=1190511912Any suggestions on getting a cheap pump with motor?
The word "cheap" turns this sentence into an oxymoron. These items are not cheap and while it might be possible to pickup a good deal on a suitable 2nd-Hand motor from an espresso machine repair centre, the same cant be said for the pump itself. I suppose you could try your luck and contact various repair centres around the traps, you might get lucky.
Alternatively, you could buy a new combo to suit the S10 from Pedro at CoffeeParts, one of our Site Sponsors linked on the L/H side of the page, but you wont get much change out of $600 for the most economical system. All the best mate,
Mal.

Re: Rancilio S10
Mal,
that link is awesome thankyou so much. I also found the Procon website. Im not sure however whether I have the series 2 or 4 pump. What I do know now is that I definately need the external pump. Any suggestions on getting a cheap pump with motor?

Re: Rancilio S10
Hi again Ralph,
Sounds like you need to peruse "Espresso Machinery 101" to prime you with the basic knowledge and understanding before you get started on your Reno of the S10. Some great info can be found here and should hopefully answer most of your questions
.... Some good general info to be found in Wiki too,
Cheers,
Mal.

Re: Rancilio S10
All espresso pumps deliver a minimum of 8 bars of pressure. Anything less and youre not producing espresso. Espresso by definition is made by passing hot water through the grounds using at least 8 bars of pressure. The volume pumped will vary from one model to the next.

Re: Rancilio S10
the group head looks just like the one on the left of this diagram:
http://www.coffeeparts.com/ran/ran4.html
the pump looks just like 700009 on this page:
http://www.coffeeparts.com/misc/motor.html
I did some tests today pulling a shot with and without external pumped water. The results showed about half the amount of water without the pumped in water. I just used a garden water tank pump and let the coffee machine turn it on and off.
Is the purpose of the external pump to provide high pressure and low volume or a lot of volume with low pressure?
Looking at the design of the pump it looks like high pressure. Are these Procon pumps re-buildable?
I will endevour to attatch some photos tomorrow.

Re: Rancilio S10
Gday again Ralph,
Perhaps if you could post up some photos of the various parts of the machine you are referring to and that will be a great help in allowing us to help you more directly once we know what were dealing with.... Theres quite a variation in Group design, HX design, etc by the various manufacturers from older models to current equipment, so the more info you can give us the better well be able to assist. Quite apart from that though, we just love to see photos of commercial espresso machinery
;D

Re: Rancilio S10
Thanks Sparky that is most helpfull. Now I understand thethermosyphen loop, but still not the brew cycle.
When the brew solenoid is activated the port changes so that steam can enter the group and the pump is started so some water is entered to the group via the group jet. Is this correct?
Only when I look at how the pumped water enters the machine it seems that is is ported into the bottom of the thermosyphen loop (at the bottom of the boiler).
Is the pressure of the pump critical?
