A Guide To Pumps And Parts

Breast Pumps: What You Need to Know
The quick and simple guide to getting started!


Breast Pump Parts & What They Do

🔹 Breast Shields (Flanges) – The funnel-shaped parts that go on your breasts. They come in different sizes, and the right fit matters for comfort and milk flow.

🔹 Valves & Membranes – These help create the suction needed to express milk. They are small but essential!

🔹 Tubing – Connects the pump motor to the breast shields. Used in some electric pumps to create suction.

🔹 Pump Motor – The heart of an electric breast pump that powers the suction.

🔹 Milk Collection Bottles/Bags – Where the expressed milk is collected and stored.

🔹 Backflow Protectors – Prevent milk from entering the tubing and pump motor (important for hygiene and pump longevity).


When to Replace Parts?

(For optimal suction and hygiene!)

Valves & Membranes – Every 4-8 weeks (or sooner if suction drops).
Tubing – Every 3-6 months (or immediately if moisture gets inside).
Breast Shields – Every 6 months (or if they show cracks/warping).
Backflow Protectors – Every 3-6 months (or if worn out).
Pump Motor – Can last years but check for performance issues over time.


Common Questions

💡 How do I know if my breast shields are the right size?

If pumping is painful or you notice excess rubbing, you may need a different size. Nipples should move freely inside the flange tunnel.

💡 Why is my pump losing suction?

Check valves and membranes – these wear out the fastest! Replacing them usually restores suction.

💡 How often should I sterilise parts?

Daily sterilisation is ideal, especially for newborns. Use a UV steriliser or boiling water method.
