Mon ancienne pompe commençait à manquer de dynamisme. Très facile à changer.

I think that people reading these reviews might like to know that a bad pump does not necessarily exhibit low flow (or no flow) of water. Just because you are getting good flow does NOT necessarily mean that the pump is operating to specifications. My older Silvia still seemed to be pumping well, the water was flowing fast, but over the last couple of months I noticed a real drop-off in the quality of my shots. They had almost no crema and the taste was OK, but not great by any means.Since the water was flowing well, and I've been using the same beans over this period of time, I assumed the problem was with my grind or grinder. I tried changing the grind setting, replacing the burrs and even went so far as to buy a new grinder, but nothing was working, I was still getting seriously subpar espresso. Finally a friend suggested that my pump might not be giving full pressure anymore. I was skeptical - after all, the flow seemed the same as ever. But the pump was inexpensive and easy to install, so I gave it a try.My problem is solved. I noticed an immediate improvement, and after re-adjusting my grind and dose a little bit (to accommodate for the increased pressure) I am once again pulling excellent shots.The pump looks almost identical to the original one except it has a brass fitting on the output side (the old fitting was plastic). Installation took around 15 to 20 minutes and there are several youtube videos that walk you through the process. The price is very reasonable in my opinion. The new pump is also quieter than the original. Make sure you run a few cups of water through it before you reassemble the machine to ensure there aren't any leaks.I'm very happy with my purchase and would absolutely recommend this pump if you have the Rancilio Silvia.

This pump is an exact replacement for my Rocket Appartamento. After a few descalings, my grouphead started to fluctuate at ~8-9bars, the motor would turn on/off/on/off a few times every second. After a few emails to the distributor (Seattle coffee gear) their tech determined that the pump had gone bad. The cost of shipping the machine back to Seattle was well over $120, and I was quoted $200 on top of that for service. I consider myself handier than the normal person and wasn't afraid to dismantle the machine, so I did. Turns out, it's far easier to work on than expected. However, you will need a few tools to complete this repair. 7mm wrench/socket, bendy socket extension, and a very small set of hands. The only things you need to remove are the outer chassis and the water reservoir. The outer chassis can be removed by unscrewing 6 bottom screws, and loosening the two inner post screws by the inner grouphead. Once the outer shell is removed, remove the two Philips screws inside the water reservoir chassis. You'll then have direct access to the vibration pump. This is where small hands are needed. The 4 screws holding the rubber pump mounts are impossible to get to. Took me a good 20 minutes to finally free the pump by turning the screws 1/10th of a turn at a time with the longest smallest 7mm wrench I had. Move the components from the old pump to the new, making sure to use plumbers tape for the screwed brass side of the pump. There is a great video on YouTube showing this process on a Gaggia, same pump, same process. Once the new pump is in place, reverse the steps, make sure to test BEFORE you put the outer chassis back on. This will most likely void your warranty, so be sure to check before diving in. Also make sure you're capable of this fix. No shame in sending it in for service if you aren't comfortable. If you can fix things, this is easy.My espresso machine lives once again! Not bad for ~$25 and 2 hours.

I used this pump to fix my Rancilio Silvia Espresso Machine. I'm not super-handy, but anyone can do this. You just need a screw-driver, a wrench, and vice grips or channel lock pliers. It took me about 45 minutes, but once you do it and/or know what you're doing, it would probably take 15 min max.You need to take the top and back off of the machine to get at the pump. There's one screw in particular that's hard to see at the bottom middle on the back of the unit, but other than that, it's very simple and straightforward. If you do a search on "rancilio-silvia-ulka-pump-ex5ep5-replacement-procedure" you should get a page from aerotec73, and the pictures and instructions there are very clear.A few things to look out for:- There's a 220V version of this pump, so make sure you get the right one. This is the 120V version.- Also, make sure you have Teflon tape to stretch around the threads that connect the pump to the water line. Without it, mine leaked there and so I had to disconnect and then reconnect the pump.- I don't know if it's necessary because I think this pump is self priming, but I tried to drip a little water into the pump before installing it.- Lastly, be careful. Where there's water and electricity, bad things can happen. Double check to make sure the unit is unplugged when you're doing anything witha tool on this machine. This is especially important when you're leak checking it after installing the new pump.Bottom line, this pump got my Silvia back up and running. Buy with confidence.June 2018 UPDATE:Repeat customer, very satisfied. Bought a second replacement pump to keep Miss Silvia going, now in her 9th year. First replacement pump lasted 4+ years, same as the OEM pump. I use my machine several times per day, so your pump may last longer if you only use it 1-2 times per day, or it may not last as long if you use it in a high-use, commercial environment. But it's as good as the OEM pump (and may very well be the OEM pump), so you can buy this pump with confidence. Very satisfied.
