S12 Pro Wearable Breast Pump - High Efficiency
Pump Faster, Live Fuller
Not getting enough milk? Leaking all the time? We hear you. After listening to thousands of moms in our community, we created the Momcozy S12 Pro hands-free breast pump — so comfortable and convenient, you might even forget you're pumping.
Designed to feel as soft as your baby’s lips and as gentle as their latch, the S12 Pro features our DoubleFit™ Flange — an upgraded double-layer seal that molds more closely to your breast for stronger suction, fewer leaks, and a pumping experience that just feels right.
⚠️ Safety Warning

Long Battery Life
The S12 Pro portable breast pump fully charges in just 130 minutes, providing up to 7–8 pumping sessions (about 240 minutes)—enough to keep up with your busy day, whether you’re at home or on the go.
Made with BPA-free, food-grade silicone, it’s safe for both you and your baby.
Pump Whenever, Wherever
Hands-Free. Worry-Free.
No wires, no limits. This bra-fit wearable breast pump lets you pump freely on the go—whether multitasking or moving your body to exercise. It’s the perfect shortcut for moms to balance nursing and reclaim their daily lives.
Effortless Pumping
The upgraded 3 modes — Stimulation, Expression, and Mixed — mimic your baby’s natural suckling to help increase milk letdown. Each mode offers 9 adjustable levels to perfectly suit your breast.
The large LED screen is easy to read at a glance, even in the dark. Plus, the satisfying snap-on click when attaching the milk cup lets you know it’s securely locked in place—helping prevent leaks and giving you peace of mind.

Leakless Pumping Starts with the Right Bra
You need a pumping bra—not just any bra—if you notice these three signs:
1. Your breast pump keeps shifting around.
2. You experience frequent leaks.
3. It’s difficult to insert or remove the pump from your bra.
Our pumping bra offers extra support to lift and snug your breasts securely, preventing leaks. It also stretches to accommodate fluctuating breast sizes and your pump’s shape, ensuring a comfortable, leak-free pumping experience every time.
That’s why a dedicated pumping bra—especially Momcozy’s—is essential for hassle-free pumping.

All Momcozy pump parts that come into contact with breast milk are BPA-free, ensuring your baby’s milk stays safe and pure.
To maintain optimal pump performance, some accessories need regular replacement. If you notice a decrease in suction, check your parts—especially the valves—for signs of wear, fraying, or stretching, and replace them as needed.
Diaphragms, duck valves, and inserts are recommended to be replaced every 2–3 months.
Flange shields and milk collectors should be replaced every 6 months.
Many insurance plans cover breast pumps, but coverage for wearable breast pumps may vary. Some providers consider them a secondary pump and may place certain limitations on coverage.
To confirm what’s included in your plan, we recommend reviewing your insurance policy or contacting your provider directly.
Momcozy partners with leading DME providers to help you access a wearable breast pump through insurance, often at little to no cost to you.
A wearable pump does not decrease milk supply, as long as it provides strong and effective suction. Suction strength is key to fully emptying the breast, which helps maintain a healthy milk supply.
Wearable pumps like the Momcozy S12 Pro are designed with high suction power to ensure efficient milk removal, so you can pump hands-free without compromising your milk production.
