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
Do NOT use this device if you have a cardiac pacemaker, implanted defibrillator, or any other metallic or electronic implant, as it may cause electromagnetic interference or serious injury.
Pump Closer. Pump Better.
Pump more. Hurt less. Leak nothing.
With an upgraded DoubleFit™ Flange featuring a double-layer seal, the S12 Pro wearable breast pump fits more closely and securely to your breasts, helping you express more milk, more comfortably, and with less leakage.
As soft as your baby’s lips and as gentle as their latch, the S12 Pro offers a barely-there feel and a spa-like pumping experience moms love.
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.
