The Hegen Wearable Breast Pump has a maximum capacity of 170ml per pump container for pumping. For your comfort and to prevent overflow, we recommend keeping an eye on the milk level during expression and pausing the Pump Device once the milk touches the ‘Max’ line engraved on the Pump Container.
If you anticipate expressing more than 170ml in one sitting per side, simply pause the Pump Device, transfer the milk into another clean container or switch out to an empty Pump Container, and then continue pumping. This helps maintain comfort, hygiene, and optimal pump performance.
