Zomee Z2 Double Electric Breast Pump

The 2-Phase mode mimics your baby’s natural nursing rhythm by starting with quick stimulation to encourage let-down, then transitioning to deeper, slower suction for milk expression. It begins with 5 quick sucks, followed by 5 deeper pulls for a second milk release or to provide further stimulation to remove milk completely from the breast.

The Z2 is designed to be quiet and discreet, operating at 46 decibels—about the sound level of a soft hum, making it ideal for work, nighttime, or shared spaces.

To maximize output, use the Z2 Pump's modes in sequence: start with Stimulation Mode on a low vacuum level (e.g., Level 1) to initiate letdown, then transition to Expression Mode at a comfortable vacuum level (e.g., Level 4 or 5) once milk starts flowing, and after a few minutes move to 2-Phase Mode, which mimics a baby's natural feeding pattern by combining rapid and deep suction. Pro tip: make sure you're using the correct flange size to avoid discomfort and maximize output.

Yes! For the best experience, we recommend using the 2-in-1 Pumping Bra. Designed specifically with Zomee pumps in mind, the 2-in-1 Pumping Bra holds your flanges securely in place for optimal suction and comfort. It allows for true hands-free pumping, so you can multitask, relax, or simply focus on your baby while expressing milk. If using our Hands-free Collection Cups, be sure to wear with the Zomee Nursing Bra for fit.

Measuring is only a starting point — always try several flange sizes included with the pump to determine which provides the best comfort and milk flow. Sometimes finding the right size comes down to comfort and how each mom feels while pumping. We encourage moms to try the different flange sizes included in the box to find the best fit for their body. If additional sizing support is needed, moms can take advantage of our Perfect Fit Promise™ for help finding the right size. A comfortable fit can help support a smoother, more effective pumping experience.

We recommend replacing the duckbill valves and diaphragms every 1–3 months, or sooner if you notice signs of wear and tear. These softer silicone parts can wear down with regular use and cleaning and may lose their shape, which can affect your pump's performance.

There are a few ways to make the Z2 hands-free: wear the pump with the Lanyard for hands-free mobility, attach the Hands-Free Collection Cups directly to the Z2 tubing, or use a Pumping Bra with the Z2 Pumping Kit included with the pump.

The Z2 is designed with alternate pumping technology, where each breast is stimulated and expressed one at a time in a back-and-forth rhythm, rather than both sides pumping at the same time. This alternating pattern is designed to mimic a more natural feeding rhythm and can help support milk release and milk flow while offering a gentler, more customized pumping experience.

All Zomee breast pumps, including the Z2, have a fully enclosed, anti-backflow system. Pumped milk travels through the closed system straight from your breast to the bottle without coming into contact with the air, which means milk cannot flow into the pump motor, ensuring safe and hygienic pumping.
