If you have been researching breast pumps, the terms “primary pump” and “secondary pump” come up a lot — but what do they really mean? 

• A primary breast pump is a tabletop pump designed for frequent, consistent pumping sessions. This is the pump you’ll depend on most, especially if you’re exclusively pumping. It’s often the best option in the early weeks, when building and maintaining your milk supply is most important. 
• A secondary breast pump is all about convenience and flexibility. Think of it as your “on-the-go” option for work, errands, or those extra sessions that support your supply. Having it handy helps you stay consistent and avoid missing a pumping session. 

The truth? Many moms find the best routine isn’t choosing one over the other but pairing them together.

Spectra® Premier Wearable Breast Pump: The Perfect Secondary Pump 

Once your supply is established, or if you are ready for extra freedom, a wearable breast pump is a game-changer.

• Rechargeable battery – Built for busy, on-the-go lifestyles, battery lasts for 5–6 pumping sessions,  

Why Pairing the Two Works Best 

The smartest setup isn’t having to choose between a tabletop pump and a wearable—it’s giving yourself the option of both. The Spectra S1 has your back with a powerful motor and customizable cycle settings, while the Spectra Wearable offers maximum flexibility. Together, they make pumping not just doable, but a whole lot more manageable and freeing.
