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.
Simple. Easy. No Overwhelm. You’ve got this, mama! 💕
