Good Afternoon

I have a Rancilio S27 machine.  I am having problems with it right now.  It was running fine recently but started to leak water.

When we turned it on, as soon as the motor starts to run, water will come out of the coupling between the pump and the motor.  Anyone have any thoughts on what could cause this?

Thanks

Eric

Sounds like the pump's bearings. But maybe wait for other  suggestions.

I have recently acquired an S27 also. The machine has been in storage for the last 2 years. This weekend I cleaned it, plumed it in and like you am getting a leak originating at the pump. Specifically two tiny holes on the pump just under the motor (see attached picture). Unlike your machine's leak, the leak on my S27 occurs before turning the power on. I've been searching around for a solution too. I did find this other forum at home barista ( Test Rotary Pump ) with a similar problem, different machine. The community suggestion is to repair the pump. So I've come to the realization that I need to rebuild my machine's pump (Procon reciprocating pump with by-pass valve)and have turned my quest to find a repair/rebuilding kit for the Rancilio S27 machine. If rebuilding is your route, I would appreciate any information you can find.

Thanks

Cristo

Hi Cristo,

Welcome to the Coffeegeek forums! {;-)

Rotary pumps are designed to have this hole in them., also car/truck water pumps have them too.., they're called a 'weep" hole.

How much water is coming out please? They're designed to let out moisture/condensation the odd time, but water shouldn't drip from them. If it is then the seals are gone on the rotary pump indicated by leaking water from the 'weep' hole..

Oh my god I haven't tested my s27 yet but I feel it's going to have this issue.

Anyone know where a cheap replacement can be had?

Hi Nathan,

I just read on another thread were some one was quoted $150.00 dollars or so, but depending on the model (size, etc) that's needed & whether it's stainless steel or brass or not has a big impact on price. "Re: Pump leak"

The company I deal with & went to back on Feb 11/08 is a company called Simgo Ltd (Beverage Dispensing Equipment), & the man I dealt with at the time (David J. Meek) has since retired 2 or 3  years ago now., but a wealth of knowledge as are all the sales people there.
The pump I needed & purchased was a brass Fluid-o-Tech model PO/PA 204 (with balanced by-pass valve) & cost me only $65.00 new! The by-pass feature has a more stable output pressure that is not effected by changes in input (line) pressure.
There's the first company listed below in the USA that rebuilds Procon pumps for at the time quoted on alt.coffee, other coffee forums., was $40.00 but may cost more now.

JC Beverage Company

EDCO


The man to contact now is Jeremy Jones, & I'm confirming an updated price if any, after 3 1/3 years.


Simgo Limited.
5122 Timberlea Blvd.
Mississauga,
Ontario,
Canada.
L4W 2S5

Tel.: (905) 602-5800  (800) 668-3311
Fax: (905) 602-5804



P.S. After speaking with Jeremy @ 3:32pm, the cost of the exact pump is now $63.00!! {;-D

P.P.S. Tell Jeremy I sent you (all).

Strange, I was initiating the actual run through test this weekend. I dropped water down the hose and the weeping hole started leaking like crazy. Big mess. So I thought the pump was indeed hosed.

Then I remove the pump to check with more water next to the sink. I run water through it and nothing leaks at all. I had visibly seen water coming out the weeping hole before, but all of a sudden it didn't. My dad said that the bearings might dry out a little and once they wet the expand and fix the leak? I have no idea.

But now I think I will put it back on the machine and see whether it works again.

Nathan,

Do not let the pump run without water at all! Even 30 - 60 seconds can destroy the internal graphite rotor blades/vanes: http://www.simgo.com/brass2.htm
