Beaina Wearable Breast Pump Parts – Duckbill Valve, 27mm Flange, 150ml Cup (2 Sets)

Beaina Wearable Pump Parts: Designed for convenience throughout your day

When you’re pumping on the go, every detail matters. Beaina’s wearable pump parts blend comfort, safety, and fuss-free maintenance to support your routine without promising guarantees. This 2-set kit includes a duckbill valve, silicone diaphragm, a 27mm flange, and a milk collector cup with a 150ml capacity, crafted to work with popular models like Lansinoh Discreet Duo, Mammanuwa, and Nuliie S32.

Leakproof design for a more confident session

The duckbill valve directs milk flow in one direction while the silicone diaphragm and soft shield help seal the chamber. The result is a steady, one-way flow that minimizes drips and spills, so you can keep moving—whether you’re at a desk, in the car, or away from a sink—all while you express.

• One-way flow minimizes leaks during use.
• Sealing diaphragm and soft shield improve contact with the breast shield.

This combination supports a calmer pumping experience, especially in less-than-ideal spaces, letting you focus on your day rather than cleanup.

Safe materials you can trust

All parts are crafted from food-grade silicone and are BPA-free, providing peace of mind when handling expressed milk and skin contact during sessions.

• Food-grade silicone for skin contact safety.
• BPA-free materials for everyday use.

Two sets give you options for multiple sessions or on-the-go rotations. With up to 150ml (5oz) capacity per cup, you can capture a meaningful amount of milk in a compact form factor, reducing the need for frequent transferring.

Easy setup, easy care

With fewer parts, the Beaina kit is simple to install and quick to clean. The all-in-one design supports straightforward assembly and fast action when you’re getting ready for a session.

Choosing the right flange matters for fit and comfort. The included 27mm flange aligns with typical sizing and complements the wearable design for smoother suction and reduced discomfort across typical pumping sessions.

Compatibility you can count on

Beaina’s parts are designed to work with Lansinoh Discreet Duo, Mammanuwa, and Nuliie S32 pumps, enabling you to refresh or upgrade without changing your entire system.

Two sets in each purchase provide you with extra capacity or backup parts so you’re prepared for daily use and travel.
