With a focus on adaptability and comfort, the K3 blends power with a gentle feel, so you can choose the rhythm that suits you at the moment. The result is a pumping experience that fits into real life, not the other way around.

Power and rhythm that adapt to you

Three modes Stimulation, Expression, and Bionic are paired with nine adjustable suction levels, delivering a range from a light start to stronger stimulation. The suction can reach up to 300 mmHg equivalent, so you can tailor sessions to your comfort and flow. The ergonomic design aims for a smooth, comfortable rhythm that aligns with your natural breastfeeding pattern.

• Stimulation mode helps initiate let-down with a gentle start
• Expression mode provides steady milk flow at your preferred level
• Bionic mode simulates a natural pumping rhythm for comfort

Efficient, lightweight design

Each milk collector holds up to 180 ml, reducing the need for frequent refills during longer sessions. The drop-shaped unit weighs about 130 g and works with soft food-grade silicone flanges in five sizes (15/17/19/21/24 mm) to fit a variety of needs, promoting a snug and secure fit while you pump.

• 180 ml capacity supports longer pumping sessions
• Five flange sizes ensure a personalized, comfortable seal
• Double-seal flange plus easy-to-clean accessories for hygiene

Quiet, mess-free pumping

Operating at 60 dB or below, the K3 remains unobtrusive—great for late-night pumping or a resting baby. The integrated collection cup features an anti-backflow design to minimize leaks, while a single-click power control keeps things simple.

• Ultra-quiet operation for discreet use
• Anti-backflow helps maintain a clean milk collection
• Removable parts are easy to clean and reassemble

Ready for life on the go

With an 1800 mAh battery, the K3 supports multiple sessions on a single charge. A compact storage bag organizes all accessories, so you can head out without worries and keep pumping a natural part of your day.
