Spare Parts for the S32 PRO2 Breast Pump

Bought the Double-Seal Flange 24mm and my suction is completely restored — feels like a brand new pump! Arrived in just 3 days to Chicago — really happy with the speed.

The Duckbill Valve was the culprit behind my poor suction — replaced it and the S32 PRO2 is back to full power. So glad I didn't have to buy a whole new pump!

Ordered the Membrane replacement and it snapped right into place — no fuss at all. Great value for money, these spare parts are a lifesaver for any breastfeeding mom.

I got the 21mm Insert because my nipple size wasn't quite right for the standard flange and the difference is night and day — so much more comfortable during pumping sessions now.

The Milk Collector fits perfectly and is so easy to clean — I replace mine every few months just for hygiene reasons and the price is totally reasonable. Fast shipping to Houston too.

Double-Seal Flange 27mm fits well and definitely improved my comfort compared to the one that came with the pump. Only minor thing is the packaging could be a bit sturdier, but the part itself is great.

Replaced the Duckbill Valve and the Membrane at the same time — my pump now sounds and performs just like it did when I first got it. Would absolutely recommend keeping spares on hand.

I ordered the 19mm Insert and it fits like a dream. The correct size makes such a huge difference to milk output — I wish I'd known sooner to size down!

Received the 17mm Insert within 4 days here in Seattle — really impressed with the delivery speed. The insert is good quality and fits securely inside the flange with no wobbling.

My Membrane had a tiny tear and suction dropped significantly. Swapped it out with this one and the pump is working perfectly again. Great price and easy to replace — took less than a minute.

Ordered a replacement Duckbill Valve after mine cracked — my S32 PRO2 is performing exactly like it should again. The part quality is excellent and it fits perfectly.

Got the 15mm Insert and it made pumping so much more efficient. I was losing suction around the nipple before — now it's completely sealed. Genuinely wish I'd tried an insert earlier.

Replaced the Membrane on my S32 PRO2 and it feels brand new again. I was about to give up on the pump entirely — so happy I found these spare parts first. Great value.

The Double-Seal Flange 24mm is exactly what I needed after mine cracked. The silicone quality feels great and the seal is noticeably better than my worn-out original. Fast shipping to New York too.

Bought 2 sets of Duckbill Valves and Membranes — it's so convenient to have backups ready to go. The price is very reasonable and shipping to Los Angeles was quick.

The 13mm Insert is a great size for me — much better suction and noticeably more comfortable. Would give 5 stars but delivery took a bit longer than I expected, though the product itself is perfect.

My Milk Collector had a small crack and I replaced it straight away for hygiene reasons. This new one arrived in 2 days — love how easy it is to source parts for this pump in the US.

Needed a replacement Duckbill Valve urgently and it arrived the next business day — amazing! The part is solid quality and my pump is back to full suction. Amazing service from Relievoo.

Grabbed the Membrane and Duckbill Valve together — my suction went from barely working to feeling powerful again overnight. These small parts make such a massive difference to pump performance.

The 19mm Insert fit perfectly and made pumping much more comfortable and effective. Really glad these are available in the US — saves having to order from overseas and wait weeks.

Replaced both Membranes (I have two pump kits) and both snapped in easily. I do this every 2–3 months for hygiene and the price here is the best I've found. Highly recommend.

The Double-Seal Flange 24mm is well-made and creates a great seal — definitely improved my pumping output. Took about 5 days to arrive to Washington, DC which was fine, just not quite as fast as I'd hoped.

I was skeptical that a replacement Duckbill Valve could make such a difference — but wow, it absolutely did! Suction is back to what it was when I first opened the box. Super happy.

Ordered the 15mm Insert on Monday and it arrived in Queensland on Wednesday. Fits snugly and no more nipple rubbing on the flange tunnel — this tiny insert solved a big problem for me.

The Milk Collector is exactly the same quality as the original — I honestly can't tell the difference. Relievoo ships fast from within the US — no waiting weeks for parts.

Happy with the Double-Seal Flange 24mm overall — it fits well and the double seal design is much better than a standard flange. Just wish there were more size options but these 10 variants cover most people.

Ordered a Milk Collector after mine went missing (it happens with a baby in the house!). Arrived in 3 days to Burlington, VT — super fast! The quality is exactly the same as the original piece.

I bought the 21mm Insert after reading that sizing down from the flange diameter helps. It was absolutely right — so much more comfortable, more milk, less pumping time. Genuinely life changing.

The Membrane I received is great quality — I change mine monthly for hygiene reasons and this price point makes it very doable. Fast shipping to Chicago, great communication from Relievoo.

The Double-Seal Flange 27mm is comfortable, well-made and restores suction perfectly. I love that I can buy individual spare parts rather than having to purchase a whole new pump kit — great value.

Replaced the Duckbill Valve after about 8 months of use and immediately noticed the improvement in suction. These wear out gradually so you don't realise how bad it's gotten — fresh valves are a game changer!

Ordered the 19mm Insert and the 15mm Insert to try both sizes — the 17mm ended up being perfect for me. Relievoo's detailed size guide made it easy to work out which to try first. Very helpful.

The Milk Collector arrived safely packaged and clips on easily. I replaced mine after about 6 months just to be safe with hygiene — really pleased with the quality of this replacement part.

Had no idea Relievoo sold spare parts until a friend mentioned it — saved me about $200 by replacing the Duckbill Valve instead of buying a whole new pump. Absolutely amazing.

The 13mm Insert is amazing — I've been struggling with comfort for months and this little insert fixed everything. Delivery to Raleigh was faster than expected too. Five stars without question.

Bought the Double-Seal Flange 24mm as a backup to keep on hand — really good quality and I appreciate that Relievoo stocks these in the US. Four stars as I'm yet to use it but first impressions are great.

Membrane replaced and pump suction is noticeably stronger already. I've been pumping for 7 months and never thought to replace the membrane — honestly should have done it sooner. So easy to swap out.

The 17mm Insert resolved my nipple discomfort immediately — the standard 24mm flange was just too large for me. This is exactly the kind of small fix that makes the whole pumping experience so much better.

Got the Milk Collector and Membrane together — both are exactly the same as the originals that came with my pump. Very happy with the quality and the price. Delivered to Seattle in 4 days.

I ordered the Double-Seal Flange 27mm because my nipple kept rubbing the tunnel of the smaller size. What a difference — I barely feel it during pumping sessions now. Well worth the small cost.

Replaced the Duckbill Valve and Membrane at the 6-month mark as recommended — my pump now works exactly as it did on day one. Such a cheap and easy way to maintain a quality pump. Love Relievoo.

The 21mm Insert is super comfortable and I'm getting more milk per session since switching to the right size. I had no idea inserts existed until my lactation consultant recommended them — so glad I found these!

The Duckbill Valve is good quality and easy to install. I knocked off one star only because I ordered two and one of them arrived with a small mark on the packaging — but the part itself is perfect.

So happy I found the spare parts for the S32 PRO2 right here in the US! Got the Membrane and it arrived in 4 business days. Installation is literally just a press-and-click — super simple.

The Milk Collector is well made and clips on perfectly. Compared to off-brand alternatives I've tried, this one is noticeably better quality. Four stars — just hoping they add a two-pack option in future.

The 19mm Insert fixed the suction leakage I kept experiencing — no more air gaps around the nipple during pumping. This small part made such a big improvement. Very fast shipping to NY.

Replaced the Duckbill Valve after about a year of daily use — the old one had gone slightly yellow and soft. The new one is firm, clear, and the pump sounds much stronger. Delighted with the purchase.

Great quality Double-Seal Flange 27mm — the silicone is soft and comfortable and the seal is really reliable. I ordered it on a Thursday and had it by Monday in South the US. Very pleased.

The 13mm Insert makes such a difference to comfort and output — I can't believe I was pumping without one for so long! Good price, fast delivery, and it fits perfectly inside the flange tunnel.

Stocked up on Membranes and Duckbill Valves — buying them together is great value. I change both every 3 months and my S32 PRO2 continues to work perfectly after over a year of twice-daily pumping.

The 17mm Insert is exactly what my lactation consultant recommended — I've gone from 2.7 oz per session to over 4 oz just by using the correct size. Life-changing for a pumping mom. Thank you Relievoo!

Ordered the Double-Seal Flange 24mm and it arrived in good condition. The seal is comfortable and works well — only four stars because I did have to re-order once as my first order was delayed by the courier.

Amazing — I replaced both the Duckbill Valve and the Membrane and the pump feels completely new again. My husband thought we'd need to buy a whole new unit. These parts saved us so much money!

The 21mm Insert improved my comfort dramatically — I was getting quite red and sore after sessions but that's completely gone now. Excellent quality and arrived quickly to Houston. Would 100% recommend.

Ordered the Membrane as a spare and keep it in my pump bag. The silicone quality is great — feels identical to the original part. Knowing I have a backup makes expressing on the go so much less stressful.

I've ordered the 15mm and 17mm Inserts to compare — 15mm turned out to be my size and the difference in comfort and output is remarkable. Great that Relievoo stocks all the sizes individually.

The Double-Seal Flange 27mm is perfect for me — I was struggling with the 24mm and the larger size made pumping so much more comfortable and effective. Fast shipping to New York, great product.

Super easy to replace the Duckbill Valve — watched a quick video and it took literally 10 seconds. Pump suction went from barely noticeable to really strong. Such a cheap fix, I'm so relieved!

The Milk Collector is great — solid, well-made, no leaks. I docked one star as it arrived with a very minor mark from what looks like transit. The part itself works perfectly and I'm happy with my purchase.

The 19mm Insert is the perfect size for me — I've had so much more pumping success since switching from the standard flange to an insert. Arrived in 3 days to DC. Amazing service, amazing product.

Bought the Membrane as a routine replacement at the 4-month mark — pumping feels noticeably more powerful. It's such a small cost for such a big performance improvement. Will definitely reorder.

I ordered the 13mm Insert after measuring my nipple and realising I needed a much smaller tunnel than the standard flange. Massive improvement in both comfort and milk output — should have done this months ago!

Ordered two Duckbill Valves — one to replace the current one and one as a spare. Both look and feel excellent. At this price I'll keep rotating them every few months for hygiene and performance. Love it.

Happy with my 21mm Insert — very comfortable and works well. I'd say it's a 4.5-star product if I'm being precise, only because the insert is slightly firmer than I expected. But it works perfectly in practice.

The Milk Collector is robust and easy to clean — I like that it's completely clear so I can see the volume at a glance. Exact same quality as my original. Delivery to NY was really fast.

Replaced my worn Membrane and the improvement in suction was immediate and dramatic. I pump 3x daily and had no idea the membrane was wearing out so quickly. Now I'll replace it every 3 months. Great product.

The 17mm Insert is amazing and I'm getting more milk than ever before. I was nervous about ordering the wrong size but the Relievoo size guide is very clear. So happy with the result — highly recommend!

Double-Seal Flange 27mm is very comfortable — I have larger nipples and the standard 24mm was always slightly tight. This one is the right fit for me and the double seal works really well. Fast shipping!

Got the 19mm Insert on recommendation from an online breastfeeding group — absolutely the right call! My sessions are shorter, more productive and way more comfortable. This insert is a must-have accessory.

Replaced the Milk Collector — it had developed a slight crack near the base after about 8 months of daily use. The new one is solid and the same great quality. Delivery to WA was faster than I expected!

The Duckbill Valve and Membrane combo is the best maintenance purchase I've made. Replaced both at once and the difference is extraordinary — pump feels completely new. Amazing quality from Relievoo.

The 21mm Insert is excellent and was exactly the right recommendation from my lactation consultant. Pumping is now comfortable, fast and productive. I wish I'd known about inserts from the very beginning!

The 13mm Insert is very good — much better fit than the standard tunnel for my size. I gave four stars as the packaging was slightly crushed on arrival, but the insert itself was completely undamaged and works perfectly.

At 10 months postpartum and still going strong thanks to reliable spare parts! I replace the Duckbill Valve and Membrane every quarter and my S32 PRO2 performs like a brand new pump every time. Invaluable.

The 17mm Insert made such a dramatic difference to my output that I ordered a spare one on the same day. Pumping is now comfortable and efficient — every mom with an S32 PRO2 should know about these inserts!

Ordered the Membrane replacement for the second time — same great quality as my first purchase. My pump is still performing perfectly at over 12 months of use. These parts are absolutely worth it.

The Milk Collector arrived quickly and fits perfectly — exactly the same as the original. I love that Relievoo makes it easy to maintain a high-quality pump without having to replace the whole unit. Five stars!

Ordered the Double-Seal Flange 24mm and 27mm to find the best fit — 24mm is perfect for me. Really glad I could try both sizes without breaking the bank. Both arrived within 3 days to NY. Great service!

The 19mm Insert is honestly one of the best purchases I've made since becoming a mom — I went from dreading pumping to not minding it at all. Comfort is everything and this insert delivers exactly that.

Replaced the Duckbill Valve after noticing my pump losing suction over a few weeks. The fresh valve made it feel completely new again — I'll be replacing it every 6 months from now on. Amazing spare part.
