Small Parts Make a Difference

Silicone components naturally wear over time, which can affect the seal and suction of your breast pump.

This replacement set contains the key silicone parts for the Bloome Wearable Breast Pump, making it useful for routine replacement or simply to keep on hand as a spare, so you’re not caught without the part you need when it’s time to pump.

What's included

1 × 25 mm silicone cushion
1 × silicone diaphragm
1 × valve

Bloome's washable components have an expected lifespan of approximately 3–6 months, depending on the pumping frequency

They should be replaced sooner if worn or damaged, and after long-term storage or before using the pump for another child.

When should I replace my silicone parts?


Check your silicone parts regularly for wear or damage. If your pump has lost suction, checking the diaphragm and valve is a good place to start.

The manual specifically identifies an incorrectly installed or damaged diaphragm as a possible cause of weak or no suction.
