The tweaked machine really does sound quite nice. One thing I gotta say, is that your workmanship with the sound damping material was solid. That stuff can be tricky to cut without it looking hacked apart with a buzzsaw, especially with all those added holes. Good work all around. I envy the Rancilio frame construction, as getting in and around my Gaggia is a royal pain with its unibody construction. Adding damping material to that thing would be a nightmare and totally not worth the effort (even though it's noisy as hell). The pulsor might be an interesting add-on though. I've relegated it to "travel machine" for when my group in the office wants to do some espresso, but every bit helps to reduce embarrassment when sheepishly pulling shots in front of others. I imagine the added weight to the Rancilio might be nice when twisting the porta as well.
Thanks! I was a little embarrassed of my hole cutouts, but I guess it could be worse! I used a throwaway box cutter that worked very well. Sad to hear the gaggia isnt as easy to open up :(
Thanks for that, because I looked at sound deadening mat material a few times and found the price a bit steep, but this Noico stuff is heaps more affordable! Adding that screen shot was a huge help. I will do my coffee grinder and probably an enclosure so my family can sleep in.
Wow this is a great video, another tip which makes a huge diference is if you place your machine ona soft surface that absorbs vibrations as opposed to a hard table this makes a massive difference!
Big agree! I had issues with my EK43 when I moved apartments and found that the vibrations were ‘resonating’ into the cheap countertop. Bought a thick rubber tile from the hardware store (the type used in gyms) and it made a massive difference to the sound of the grinder.
Wow, this is so similar to my journey with my Profitec Go. Same Noico sound deadening! I did use a pulsar, but did not switch the pump, however I did remount the pump on a piece of Sorbothane, which had a very similar effect. Give that a try IF you are experiencing any vibration related noise. Do a quick search online - there is an ANCIENT post about a fellow who installed water hammers to his Silvia, apparently to great effect. Next step for me is to switch to plumbed to free up space, then Arduino + Rotary pump and to likely replace the basic PID. Cheers!
Great job! Thanks for interesting ideas and comparing machines with and without mod on each step. I'm going to do something with my crazy loud Dedica machine too. It's very loud now.
FYI: The pulsor actually increases water debit a little bit! I liken it to a reservoir capacitor in a linear power supply - it's filling in the dips where the vibe pump piston is retracting. The Lelit pump is much lower (~30% or so) throughput than a standard EP5 - the MaraX has a 4.5ml/s water debit. With yours, I'm seeing a bit over 5. I've seen people put pulsors in BDBs which have a largely unrestricted water path, it'll push the debit up from 6-7 to 8 and change.
@@davidfuller581 What I was trying to convey was that the word debit does not have the meaning I believe you are attributing to it in the English language, and I did look it up before I posted to double-check.

I did the same mods on my Gaggia Gaggiuino. I love it!! The machine sounds like something much more expensive. I had it for many months now and no problem at all with the deadening material and heat.
Do you have a build log on your Gaggiuino? I want to do the same for my Silvia Gaggiuino. Do you add the Pulsor to the new pump as well? Did it change your Gaggiuino build at all? Thanks!
@@willcarter4950I do not have a build log. I only have a few pictures. I did had the pulsar to the pump and dampening mat to the inside of the machine. The machine is amazingly silent and it hasn’t changed anything to the behavior of the Gaggiuino.
Good luck with that one 😂. The sette may just have too little material around the noisy bits. 😅 Loved the sette except the noise. Even considered doing some sound deadining. Wasn't too mad when it finally decided to eat his own gears and replaced it with a Eureka Mignon. Not the quietest but way better.
Cool seeing your projects again. My solution to sound is to stick with lever machines. Hahah I look forward to seeing what you did to the gs3. I know Bay Area Coffee community miss you but hope you are enjoying Chicago.
Cool. I installed pulsor about a year ago on my Silvia. It was about that time I swapped the EP5 pump for an EP4. Slightly different (slower) ramp-up .. and an improvement to my coffee. Insulation is interesting. I've only done the boiler with 5mm silicone sheet. Your Pro is definitely quieter than my old Silvia. Long may she run!
wow, the EXACT video that I was 'thinking' about, but was not searching for and it shows up in my yt feed!! Thanks for that info, VERY helpful!! I'm going to start with what looks the easiest to install with the butyl dampener sheets.
good stuff! I'm glad you mentioned that about the pulser. I put one on an old Starbucks Barista and it did not make a significant difference in noise but it's not a daily-driver machine. I've gone so far as to upgrade an old Giotto to a rotary pump which has a nicer sound.
@@jaysonmorales9898 no clips, sorry. I basically rebuilt and re-plumbed the machine from scratch, making brackets, soldering custom pipe and modifying the thing as necessary. Definitely not a simple swap job. fittings are metric pipe with BSP thread if memory serves. Good luck.
@@tatemazer It's not difficult but you do need some tools: a hacksaw, a small tubing bender, the ability to silver solder pipe fittings (with MAP gas torch). and supplies. typically 1/8 BSP fittings and 6mm tubing for classic Italian units --sometimes 1/4 BSP (Stefanos's and Espressoparts are good suppliers). BSP comes in taper (BSPT) and parallel (BSPP) so mind the difference.
We loved this video. Always, thinking about vibrations on machines as we take them apart and put them back together when we are repairing espresso machines.
So cool to see the Factory Coffee logo on one of your espresso cups and to then find that its made by Grayling Ceramics. Both are located in my hometown!
Would love to see a follow up with the role of the seperate additions. So compare the pulsor to the padding. Also pulsor plus padding on the old pump versus the new pump. That way different budgets can make the right choice
Interesting that you didn't add rubber mounting to the pump or any vibrational parts. In addition, I would consider using fabric tape in between where the panels meet the base and are otherwise meeting at the seems. In keyboards it's called a Force Break mod, and it makes a huge difference. BTW keyboard modders use the same and similar insulation.
@@tatemazer .. Then try adding that tape is the next step I would try. It's inexpensive and makes a huge difference. It's more about sound isolation between the panels and base.
I was thinking exactly the same, thats going to possibly cause issues later on when that excess heat cooks the insulation on the wires and it all goes brittle and falls off.
if I can add anything It would definately be to not add the silent pump, cause 1. Its waay more expensive than its worth and 2. It'll lower your water debit a little too much on e61s, in fact on my maraX I actually took out my glicleur because the water debit was too low for my liking especially if you are doing anything high extraction. In fact, even taking out the gliceur (not reccomended) the water debit was still too low. If you want something closer to the silent pump from the standard, I would reccomend the ulka ex4.
I wish there was dB meter used to quantitatively compare the results, but either way this video motivated me to do one or all of these improvements! Thanks!
Circled back to your video to thank you for the sound deadening mats! My Expobar went from a yelling volume to a talking volume. Just in time for my apartment move
Awesome video and definitely an underrated aspect of machine selection in my opinion! I have the Appartamento myself and live in an apartment, so I can relate to the guilt. Hope you'll make a similar video for your Rocket! Keep up the nice work
@JackBrainStem - I just replaced the tiny worn plastic ball valve in my 12 yr old Breville Dual Boiler Ulka pump with a Pyrex glass one after it stopped pumping water. It is now way quieter when pulling a shot. Like Tate's mod, I can now hear the espresso filling the cup. It is louder though when pulling some hot water, so go figure? One thing - one of the screw mounts for the rubber vibration mounts fell off so it now has 3 screws holding it instead of 4. Who knows if that helps? Thanks Tate for your efforts
The only other things you could consider now that the pump is as quiet as it can be and the chassis is acoustically dampened would be to block the sound by tenting a bit of mass loaded vinyl around the pump if space allows, installing sound absorbing acoustic foam on panels if there’s any space to do so which would convert any sound vibrations that strike it into heat, and lastly maybe put some kind of thin foam or rubber gaskets between any sections that don’t sit tightly against each other and allow for potential sound leakage. There’s be very diminishing marginal benefits to all of this.
I'd love to see what similar things can be done to a Gaggia Classic.. also if you can somehow use the sound dampening material (or any other mods) to make grinders quieter. Grinder noise is way worse than espresso machine noise IMO.
Do you know which parts? I would like to try and replace the pump for oleb silent green and add a pulsor, but I'm but sure if it will fit GCP. Dimensions are almost identical.
@@vukasinnesovic4644 vibe pumps are mostly interchangeable. Not certain the pulsor will fit. You'll have to check yourself. And of coarse the deadening material could go on any machine
I did the car insulation also, looks like I need to buy some more as I forgot to do the bottom of the machine! I also found the pulsar so not really do much (but I did the car insulation at the same time) How do you find the water tank's lid and the silicone hoses?...for me this is the most noisy thing as the hose rattle is super loud...I find I either need to keep the machine full of water or simply remove the lid when pulling a shot. I did use cabinet door buffer stickers and it helps a little.
This was a brilliant video. Very entertaining and informative. I've always wondered if someone would try and make their vibration pump quieter. Question: I know that rotary pumps are much bigger than vibration pumps but it looks like there is enough space inside the Rancillo for one. Would you have consider installing a rotary pump in your machine? I hate the sound of vibration pumps so much that my dream machine in the Olympia Cremina.
Great video. May i ask if there is any different fittings needed for either the plumbing or the electrical connections when exchanging the pump for the Lelit Mira pump? I'm looking to do this modification myself and am unsure if it's just a simple case of exchanging the pumps or if any different fittings are required. Thanks!
Fitted the OLAB/Pulser/Butyl to my Silvia today for a total of €50/$54. The difference is night and day! Now I’m wondering if audiophile-grade feet would stop a lot of the remaining vibration from going through the worktop.
Did you put a pulsor only at the brew pump or also at the service boiler pump? If both, it would be interesting to know how you installed it for the service boiler. I think an additional fitting is necessary here to avoid contact with the boiler (not enough space for the pulsor alone)
wondering if pulsor and sound deadening box just around pump would do? concern is heat buildup inside machine effecting electrical/electronic components
Het Tate, great video! Im thinking to do all I can to make my Appartamento more quiet, maybe a rotary pump if possible. Quick question - will the sound deadening wrap negatively affect thermal cooling and overheat the internal environment inside the machine?
Hey Chris, thanks! So long as you avoid blocking the ventilation holes at the top of the machine I believe you should be ok. The components in there are rated to run plenty hot and the electronics are fortunately pretty low in the machine.
Did you also change the service boiler pump? I am not sure to do it on my machine. Because of the ~1/3 lower flow rate and time controlled pump cut-off after activation the service boiler will not be refilled to the regular level. Will still work (if to low, pump is activated) but with less steaming power I guess?
I only used it on the brew pump since I don't steam very often. The steam boiler will still fill to the same level since it is still depending on the fill probe to check the water level. The only issue you might encounter with replacing the steam boiler pump is during the initial fill of an empty boiler. It'll probably trigger an alarm thinking the steam boiler isn't filling, but it's just slow. I've had similar experiences on another machine and I just power cycle it once or twice during that first fill
@@tatemazer Thank you so much! The second OLAB Silent Green is already here, waiting for some spare time. Plus a 90° fitting and a second Quickmill pulsor. Add some aluminum butyl and the machine will become really quiet. Where I live, in Europe, OLAB Silent Green costs about 30 EUR. So it's not really expensive to change both pumps. Talking about the Lelit assembly, this is really expensive but not necessary. You only need the pump
Great vid! can you explain or estimate the difference between "changing pump + adding sheets" and "adding sheets only", coz changing the pump is kinda a bit difficulty to me, thanks a lot!
Hey people. If you do these mods, don't buy the pump from 1st Line. It's like half the price on Coffee Addicts. Also, they aren't assholes. Also FYI, a Gaggia Classic Pro Evo doesn't have room for a pulsor.
Im thinking about damping the machine too but im unsure about thermal heating and its effect on electronics inside. Yours now in place for a couple of months. Did you see any problems? Cheers!
ive been meaning to try the diaphragm that delonghi makes for their automatic machines, there is a guy that put one on a machine in a video in yt and it made a substantial difference in the video he made, seems to work on yours too! one thing that worked for me that I didn't do on purpose for noise was adding a dimmer knob to the pump. I haven't measured what the voltage change is but if I just turn down the dimmer a tiny bit, with a zero pressure load flow rate change of less than 1g/s the volume and frequency of the pump is substantially better. with this and the gaggiuino mod installed on my delonghi stilosa the noise is very very minimal during a shot, videos on my channel where i've modded the software to have stop on weight and touch screen controls #notanad lol..
check out the comparison between the stock machine and sound dampening at 9:13 . It definitely makes a difference! Hard to say it is the most substantial, though. They all help
An SPL meter only measures loudness not frequencies. The audio gives, imo, a more useful impression of the effects of the mods because it demonstrates the sound before and after.
Do you feel like the deadening material could also be put inside the housing for the front around all the buttons/PID/etc? Any reason you did not put it there?
I finally finished this mod to my machine (it was disassembled for me to rebuild my steam valve for nearly a month...) and to anyone else watching this video, I would say the deadening material is the most significant and easiest upgrade here. ESPECIALLY placing the deadening material near the pumps. I forgot to do the underside initially, and while I noticed some difference, after applying to the underside just under the pumps themselves, WOW is this machine quiet now. Thanks for the idea@@tatemazer!
I think that installing a rotary pump would solve both the noise and pulsation for probably the same amount of money of all the mods. A downside is that there’s not enough space for one in most machines so you’d have to install one externally.
@@tatemazer That’s surprising (to me but good to know). Have you looked at how the rotary pump mounted in the GS3? Is it perhaps bolted directly to the frame without isolating rubbers? Thanks for your excellent video!
definitely! I brushed over this in the video, but I found that Db didn't really give the whole picture, since this project was more about shifting the annoying higher-pitched noises with a more pleasing dull hum. In all the comparisons, the audio sensitivity was the same, so you can make your best judgement! Hope that's helpful 😊
Frankly speaking, Rancilio is making fun of us. It's unacceptable to sell a so noisy $1500 coffee machine, with a so inconsistent driptray on top of that. Those issues should have been fixed for years. Deal breaker for me. It's not the customer's role to find a solution for that.
The tweaked machine really does sound quite nice. One thing I gotta say, is that your workmanship with the sound damping material was solid.

Did you put a pulsor only at the brew pump or also at the service boiler pump?
If both, it would be interesting to know how you installed it for the service boiler. I think an additional fitting is necessary here to avoid contact with the boiler (not enough space for the pulsor alone)
Only the brew pump!
Recently I came across soft rubber pump mounts, "Rubber Vibration Pump Support Foot," (
wondering if pulsor and sound deadening box just around pump would do? concern is heat buildup inside machine effecting electrical/electronic components
Yay! another video from Tate!
Hope you enjoyed it!
Really cool to see you back! Just curious but why did you redact where you’re working at now?
Well done, nice mod,Hats off!
Het Tate, great video! Im thinking to do all I can to make my Appartamento more quiet, maybe a rotary pump if possible. Quick question - will the sound deadening wrap negatively affect thermal cooling and overheat the internal environment inside the machine?
Hey Chris, thanks! So long as you avoid blocking the ventilation holes at the top of the machine I believe you should be ok. The components in there are rated to run plenty hot and the electronics are fortunately pretty low in the machine.
@tatemazer thanks!
Does that pump fit other machines like ECP delonghi models?
Hi its a typical vibratory pump size, so it should fit!
Did you also change the service boiler pump? I am not sure to do it on my machine. Because of the ~1/3 lower flow rate and time controlled pump cut-off after activation the service boiler will not be refilled to the regular level. Will still work (if to low, pump is activated) but with less steaming power I guess?
I only used it on the brew pump since I don't steam very often.
The steam boiler will still fill to the same level since it is still depending on the fill probe to check the water level. The only issue you might encounter with replacing the steam boiler pump is during the initial fill of an empty boiler. It'll probably trigger an alarm thinking the steam boiler isn't filling, but it's just slow. I've had similar experiences on another machine and I just power cycle it once or twice during that first fill
@@tatemazer Thank you so much! The second OLAB Silent Green is already here, waiting for some spare time. Plus a 90° fitting and a second Quickmill pulsor. Add some aluminum butyl and the machine will become really quiet.
Where I live, in Europe, OLAB Silent Green costs about 30 EUR. So it's not really expensive to change both pumps. Talking about the Lelit assembly, this is really expensive but not necessary. You only need the pump
Great video …so wich Lelit models carry the quietest pumps ..The sound insulation isn’t hazardous?
nice one! Did Guy posted anywhere about how he did it on the Decent? I want to apply to mine.
Me too!
Thanks! Sadly no :(
no but i have talked to brian quan about making a video. i should get on that
Great vid! can you explain or estimate the difference between "changing pump + adding sheets" and "adding sheets only", coz changing the pump is kinda a bit difficulty to me, thanks a lot!
Thanks! I'd say they make a similar impact
Hey people. If you do these mods, don't buy the pump from 1st Line. It's like half the price on Coffee Addicts. Also, they aren't assholes. Also FYI, a Gaggia Classic Pro Evo doesn't have room for a pulsor.
thanks for the tip!
Good video Tate!
Im thinking about damping the machine too but im unsure about thermal heating and its effect on electronics inside. Yours now in place for a couple of months. Did you see any problems? Cheers!
No problems! The electronics sit very low in the machine and away from too much heat.
Have you look at destructive interference noise canceling
Have you tried two pumps in parallel?
Lower flow rate without resistance doesn't mean anything
I suppose i could try this after my warranty expires😅
ive been meaning to try the diaphragm that delonghi makes for their automatic machines, there is a guy that put one on a machine in a video in yt and it made a substantial difference in the video he made, seems to work on yours too!
one thing that worked for me that I didn't do on purpose for noise was adding a dimmer knob to the pump. I haven't measured what the voltage change is but if I just turn down the dimmer a tiny bit, with a zero pressure load flow rate change of less than 1g/s the volume and frequency of the pump is substantially better.
with this and the gaggiuino mod installed on my delonghi stilosa the noise is very very minimal during a shot, videos on my channel where i've modded the software to have stop on weight and touch screen controls #notanad lol..
I've always wanted to do this! And you have my machine! Pro X wouldn't make a difference though, right?
Nope! Basically all the internals are the same 👍
How much of a difference did the sound deadening make compared to the pulsar and new pump?
Are these 3 mods going to work on a Gaggia classic?
Awesome work once again, thanks for taking the time to make a video and posting. Cheers
I have a SPX, do you think just doing the sound dampening alone would make the most difference in sound? The pump is out of my price range.
check out the comparison between the stock machine and sound dampening at 9:13 . It definitely makes a difference! Hard to say it is the most substantial, though. They all help
Would it be quieter if it was possible to put a rotary pump, is it very difficult to find one on the market and put it inside?
You are doing the lords work my dude. Supremely helpful.
You might better use SPL meter to know how much the noise is 🤔before and after?
An SPL meter only measures loudness not frequencies.
The audio gives, imo, a more useful impression of the effects of the mods because it demonstrates the sound before and after.
ESP32 at 10:00. Nice!!
great video! Which tweak would u say made the most difference for you?
Thanks! It seems the pump made the biggest impact but the dampening is a close second!
damn that is a huge difference
You could have bought a Fluid-o-Tech nsf 24V DC rotary vane pump for the price of that Lelit Silent Vibration pump..
Wow where?! I've purchased new ones before and it always been several hundreds of dollars
Not if you buy it from Italy. €162.50
@@sxair2285 wow great deal! Drop a link!
Great video! I'd love to know more about what your friend did to his decent - i've got a DE1XL... any chance you can share a link?
Thanks! Sorry he didn't make a video :(
no video but happy to answer questions
can you please make a video for rancilio silvia x pro e01 error fix
like is this easier or would swapping a mara x pump just be easier
The sound deadening material is a great mod. Does it tolerate heat well? Kinda scared it's going to off-gas some nasty smelling chemicals.
Thanks! Yes it's rated for 212F and I don't have it touching any boilers directly so it shouldn't be anywhere near that. No smells either thankfully 😅
@@tatemazer sweet, thanks. Definitely doing this myself.
To make the coffee machine even quieter, place it on squash balls (PRO - with two yellow dots)
Oh interesting idea, thanks for the tip!
great video 👍
Does the Pulsor alone affect the flow rate ? Thanks!
I don't believe so!
Do you feel like the deadening material could also be put inside the housing for the front around all the buttons/PID/etc? Any reason you did not put it there?
It definitely could! I'll admit it was pure laziness lol I didn't want to unplug all that stuff and I was happy with the results
I finally finished this mod to my machine (it was disassembled for me to rebuild my steam valve for nearly a month...) and to anyone else watching this video, I would say the deadening material is the most significant and easiest upgrade here. ESPECIALLY placing the deadening material near the pumps. I forgot to do the underside initially, and while I noticed some difference, after applying to the underside just under the pumps themselves, WOW is this machine quiet now. Thanks for the idea@@tatemazer!
Next you just need a lever machine... Benchmark for quiet ;)
what would it take to install a rotary pump? Some dude on Instagram did it on his ECM
I think that installing a rotary pump would solve both the noise and pulsation for probably the same amount of money of all the mods.
A downside is that there’s not enough space for one in most machines so you’d have to install one externally.
You can't just put a rotary in. Doesn't work. Too much unregulated pressure
Good idea! I thought about that, but I've found that my gs3 with its rotary pump is surprisingly much louder than my Silvia is now.
@@tatemazer That’s surprising (to me but good to know).
Have you looked at how the rotary pump mounted in the GS3? Is it perhaps bolted directly to the frame without isolating rubbers?
Thanks for your excellent video!
What is the chance to have the machine overheating with all that insulation?
I haven't noticed any change in temperature. Fortunately the boilers are insulated so the inside of the Silvia pro tends to run very cool.
4:41 what Cups are these? Thes Look fantastic
Link in the description!
Awesome ✌
Great video! Can you make a video on how to make a grinder quieter as well?
Do those parts fit Rancilio Silvia V6?
Yes! Most parts are interchangeable between those machines
aww bro.. so easily could have used a Db ap to give a reading..
definitely! I brushed over this in the video, but I found that Db didn't really give the whole picture, since this project was more about shifting the annoying higher-pitched noises with a more pleasing dull hum. In all the comparisons, the audio sensitivity was the same, so you can make your best judgement! Hope that's helpful 😊
Which machine do you like better - Rocket or Rancilio?
Rancilio is a much better bang for your buck but I'll admit I mostly bought the rocket for the aesthetics 😍
@@tatemazer I have owned the Silvia (PID)with a niche zero for about 3 years - I was thinking of upgrading to a rocket ? Would it be an upgrade ?
mostly a pump difference, and dropping 170$ for this seems unjustified. was hoping for something else
Frankly speaking, Rancilio is making fun of us.
It's unacceptable to sell a so noisy $1500 coffee machine, with a so inconsistent driptray on top of that. Those issues should have been fixed for years.
Deal breaker for me. It's not the customer's role to find a solution for that.
Does Guy have a video for how to do the decent?
No sorry :(
no but happy to answer questions
How did you get rid of buzzzing drip tray?
Hmm my drip tray was never buzzing before, is it possible something on your machine is loose or miss-aligned?
@@tatemazer I don't know what exactly is wrong with my machine. it's lelit grace and all the parts are full metal, so they are buzzing
@@tatemazerok, I think my main issue is huge vibration when pump is working, so even cups getting moved
