S9 pro Milchpumpe
Ich hatte ein Problem mit meiner Milchpumpe von Momcozy, da sie plötzlich nicht mehr funktionierte. Der Kundenservice hat schnell reagiert, und innerhalb von 48 Stunden habe ich eine neue Pumpe erhalten. Die Milchpumpe ist wirklich sehr gut und pumpt die Milch effizient ab. Ich bin sehr dankbar für die schnelle und unkomplierte Lösung.Super Zufrieden 🤩🤩

Momcozy
The battery life is short but is very good
Best invitation
I'm a on the go mom with 4 kids, this makes life a breeze. It's exactly what you see in the picture and it works great.
Perfect pump
Love love I bought my first one at Walmart and my children broke one and I had to buy one again and came on time and perfect condition
Convenient!
Love these so much I bought them for all my pregnant friends too!
Me encant
Lo s per recomiendo es s per pr ctico
Top of the list for your baby registry
Easy hands free pumping while you do things that need to be done. No stopping to be plugged up to an old school pump.
Fits perfect
Its authentic, really fits my Momcozy breast pump.
Life Savor
Perfect replacement saved the day for my daughter in law
Does it s job
Works good, compatible like it says!
Great
Working good

I accidentally cracked my original one and this one works great.
Good product!
Would get this again if I had another baby
Works for MomcozyS12Pro
These will work mine is the momcozy S12 Pro the only difference is the silicone flange part? it is different than the original. I bought it as a backup so i don t have to wash every time i just use my other set.
S12 pro replacement
Perfect fit for the MomCozy S12 pro
Must have for pumping mamas!
I ve only had this pump for two days, but it s been such a game changer and blessing! I love not being hooked up to a machine for hours at a time. It s so simple and easy to use! (I wanted something that wasn t too complex and this took the cake!)Great suction, simple design and easy to use!One thing to note, it is pretty loud but as long as that doesn t bother you, it s a great unit. Momcozy is such an amazing brand too!
Lo mejor de los extractores
Para mi la mejor compra que he hecho desde que tengo mi beb , super pr ctico, bastante poder de extracci n y con buena durabilidad de la bater a.
Buy replacement parts for breast pump before you need it.
Replacement parts were a perfect fit. I don t worry about it not working or loosing a piece of the breast pump.
Best hands free pump and most affordable
10/10 would recommend this is the first ever pump I bought and it gives me the best output and doesn t hurt while pumping! This product has definitely helped with my milk supply
Long Battery Life, Stable while moving
Don t know what I would do without this pump. The battery life is the best part, I can run a couple pumps off of one charge. They stay secure while I am up and moving around, and they re relatively quiet. I bought a separate Willow pump case (hard) because it doesn t come with one and it fits well in it! I got one free through my insurance and bought another one because it s been so crucial for us
Better than expected
I was told a few times this wasn’t too good of a pump, but more times I did hear the suction was good. My milk supply has went from 1-3 ounces to 4-8 ounces! The suction is great and I only use setting 2 of 9. I had an issue with the pump opening and leaking, but customer service handled everything so fast and smoothly. This is the pump I recommend whenever someone asks or mentions them when I wear it. They are comfortable I don’t notice I have them on other than the size.
5 star
Very powerful effective pump. Only downside is that delivery was slow.
Excellent
The right part I needed

Really Impressed!
Have used Momcozy with my third baby and now again with my fourth. I am so far delighted with the products, find them so easy to use and great price too. Have used the S12 as well as the S9. I also have to say thanks for the exceptional customer service provided by Momcozy, very efficient and understanding of my circumstances. Would definitely purchase again in future!
excelente manos libres
este extractor es ideal para madres que necesiten realizar sus extracciones mientras trabajen, realicen sus quehaceres domesticas, en mi caso lo utilizo mientras estoy en la oficina sin tener que hacer una pausa en mis pendientes, es super comodo para trasladarse, tener las manos libres da libertad
Get these!
So I started my relactation journey 3 days ago. I m 5 weeks postpartum and my baby had to be formula fed due to the failure to thrive. So now that s she s doubled her birth weight I decided I wanted to try it. I heard good reviews on this pump. Yesterday I thought about quitting due to the pain well come to find out it was the wrong flange size. I put these pumps on and used the correct size and I somehow managed 2 oz from both breasts. Keep In mind I d only been getting droplets. These emptied me. They didn t hurt either and I m so happy about it.
Get It
Made a world of a difference when pumping. Thin easy to install. I find that I m comfortably expressing more milk.
Amazing
Easy to use
Easy
Loves these! Love how I am able to do things with them
comfortable
Love this pump! It is comfortable against my skin, easy to work, and pulls all the milk out my boobs unlike others i have tried! It s very simple to clean and store, so glad i got this pump! Not too bulky either to wear out in public if you need to pump for dinner!
Amazing pumps!
Literally love my momcozy pumps so much! As an exclusive pumper, these are my everyday pumps because I get more output with them than my hospital grade pump!
the quality
This product helped me a lot because whenever I m in a hurry, I can leave my baby with someone and it helps me have enough milk.
Great Find!
absolutely loved these! They made pumping so much easier on the go!
Perfect pair with Spectra!
These have been a lifesaver! I ordered an adapter piece from legendairy milk to use with my spectra to make it hands free and it has been *chefs kiss*!

Do customers commonly report needing replacement parts or successfully using third‑party adapters (e.g., Spectra / Legendairy) with the S9 Pro?
Not commonly — only a few reviewers mention needing replacement parts. When issues did occur customers reported quick service (one reviewer received a replacement within 48 hours), replacement parts fitting well, and at least one reviewer successfully used a Legendairy adapter with a Spectra to make the S9 Pro hands‑free.

Can all milk‑contact parts (flanges, collectors, valves, diaphragms) be fully disassembled and safely sterilized by boiling or steam sterilizer? Are any parts NOT safe for heat sterilization?
We confirm the milk‑contact pieces (flanges, collectors, valves, diaphragms) can be fully disassembled for cleaning — they’re made of food‑grade silicone and PP and are removable. However, Momcozy explicitly advises NOT to heat‑sterilize (boiling/steam) or place the washable parts in a dishwasher or microwave; wash the parts carefully by hand and air‑dry instead. [1][2]

product_description; FAQ
What is the actual suction strength at the highest setting expressed in mmHg or kPa, and how does it compare to common hospital‑grade or popular personal pumps?
We list the S9 Pro’s working vacuum as about –165 to –285 mmHg in expression mode (the maximum/highest setting ≈ –285 mmHg, which is about 39.0 kPa); stimulation mode is lower (approximately –85 to –145 mmHg). That peak (~285 mmHg) is within the same range as many hospital‑strength/home hospital‑grade pumps (popular models commonly advertise ~270–300 mmHg), so S9 Pro’s highest setting is comparable to those hospital‑strength personal pumps.

Are replacement silicone diaphragms, valves, collectors and other wear parts available from Momcozy (or recommended third‑party sellers), and are parts interchangeable with brands like Spectra or Haakaa?
Yes — replacement silicone diaphragms, duckbill valves, milk collectors, flange inserts and other consumable parts for the Momcozy S9 Pro are available through Momcozy’s replacement-parts/accessories listings and are also sold by major retailers and third‑party sellers. Parts are model-specific, so we recommend Momcozy replacement parts for best fit, though many shoppers buy S9‑compatible third‑party kits from retailers; Momcozy wearable collection cups can be adapted to pumps like the Spectra S1/S2 with an adapter (for example Legendairy Milk adapters), but diaphragms/valves are not broadly interchangeable across brands without explicit compatibility.

Does the used unit show any signs of wear that could impair the silicone seal (cracks, hardening, discoloration) or any internal milk residue that would require part replacement?
We describe this as a gently used unit in good condition: you may see minor surface scratches or light stains, but the food‑grade silicone flanges and sealing edge are flexible and show no cracks, hardening, or discoloration that would impair the seal. We did not observe internal milk residue; note the listing indicates the cleaning brushes are missing, so we recommend thoroughly washing and sterilizing all removable silicone parts before first use.
product_description; condition notes; features & specs
The spec lists noise ≤50 dB—is that noise level realistic when worn under clothing and during double‑pumping in everyday use?
We list the S9 Pro’s operating noise as ≤50 dB. In everyday use that level is comparable to a quiet conversation and is usually noticeably muffled when the pump is worn inside a bra or under clothing; double‑pumping can produce a little more vibration or a two‑source sound but a snug fit and thicker fabric typically keep it unobtrusive. For quieter use, wear the pump snugly in your bra and avoid thin, loose outer layers.
