As a Certified Lactation Counselor (CLC), one of the top questions I hear is:
“Do I need more than one breast pump?”
Whether you’re exclusively pumping, returning to work, or pumping occasionally, understanding the difference between a primary breast pump and a secondary pump can help you protect your milk supply and make pumping easier and more comfortable.

“Primary” vs. “Secondary”- What does that even mean?
The term “primary breast pump” is used in the pumping world to describe a pump meant for frequent use. Primary pumps are essential for exclusive pumpers, because they are used 8+ times a day, often for months at a time.
The term “secondary breast pump” is used to describe a pump that may offer more flexibility, but contains a motor that may not empty you as well, and may not withstand heavy use.
More on these terms soon! But first…
First, let’s address the hospital-grade elephant in the room.
The term “hospital-grade is often misleading. Primary pumps are often referred to as “hospital-grade” or “hospital-strength” breast pumps because they’re built for frequent use. However, there are only two or three pumps that are up to the task of being a multi-user durable pump used in actual hospital settings. (This should probably be in a category all its own.) Mommas rarely own one, as the price point is very high. You might be able to rent one, though, if you want to look into it! These pumps are: Medela Symphony and Ameda Platinum. Older hospital pumps might still be used, like the big blue Medela Lactina and though rare these days, I’ve even seen the dinosaur Medela Classic pump still used in the hospital setting.
Now that we got that pesky “hospital-grade” term of the way, let’s talk PRIMARY PUMPS:
🍼 What Is a Primary Breast Pump?
Your primary pump should be your main, full-powered breast pump — the one designed to maintain your milk supply through consistent, efficient pumping sessions. If you’re an exclusive pumper or a working mom pumping multiple times per day, your primary pump is essential for maintaining and protecting your milk supply.
Primary pumps typically feature:
- Strong suction and adjustable settings for comfort and efficiency
- Closed-system design for hygiene and milk safety
- Plug-in or rechargeable power for reliable performance
- Long motor lifespan designed for daily pumping
Examples of top-rated primary pumps:
- Spectra S1 (blue, rechargable) or S2 (pink)
- Medela Pump in Style
- Motif Luna
- Unimom Opera +
- Cimilre S6
Here in the U.S., most mommas can get a pump free through insurance. I highly suggest getting your primary pump through insurance, and putting a secondary pump on your registry or investing in one out-of-pocket.
💼 What Is a Secondary Pump?
A secondary breast pump is your portable or wearable backup — designed for greater flexibility and freedom. These pumps are perfect for moms on the go, travel days, or quick pumping sessions when you’re away from your main setup.
Secondary pumps are convenient, but they aren’t designed to replace a high-quality, hospital-strength primary pump for full-time milk expression.
Secondary pumps usually offer:
- Lightweight, compact design
- Rechargeable or battery-powered operation
- Quieter and more discreet use
- Easier hands-free options
Popular secondary or wearable pumps include:
- All wearable breast pumps
- Portable pumps with cup attachments
- Baby Buddha 2.0
- Pumpables Genie Advanced
- All manual pumps
A wearable pump can make it easier to multitask while pumping, helping you express milk discreetly. However, from clinical experience, it has been found that they just do not empty as reliably as a primary pump.
Why? A few reasons. Secondary pumps often have a cheaper, simpler motor which lacks the strength and/or durability of a primary pump. Secondary pumps don’t always offer as wide a selection of flange sizes, which can lead to poor pumping efficiency and efficacy.
Every body responds to pumps differently.
Everybody is different and every BODY is different. One momma may respond fabulously to the Baby Buddha 2.0 and use it as their primary pump, and that is OK! Another momma may not love the vibration of a Spectra S1 and wonder why everyone loves them so much. Unfortunately there’s literally no way to know how your body will react until you try a specific pump. My advice? Contact your local lactation professional and see if they have pumps and different flange sizes and styles you can try out. Seek out a friend of family member who has a breast pump and will let you try it. Do your research and pick one free with insurance. If it works for you, awesome. If it doesn’t, see if you can get another new or gently used pump in a local mom group or online. You might even choose to buy one out of pocket.
⚖️ How to Choose the Best Breast Pump Setup
| Pumping Situation | Recommended Setup |
|---|---|
| Exclusively pumping | Primary pump + portable or wearable secondary pump, manual pump as a back-up |
| Pumping at work daily | Primary pump if you pump in a stationary way (sitting down, close to an outlet), portable or wearable secondary pump if you need the flexibility |
| Occasional pumping | Any pump you respond well to, honestly! |
| Traveling or commuting | Lightweight wearable or portable pump, manual pump as a back-up |
Your pumping setup should match your lifestyle and goals. Think of your primary pump as the foundation of your milk supply and your secondary pump as your freedom tool — giving you flexibility without compromising output.
💡 Pro Tip from a Certified Lactation Counselor
If you notice a drop in supply or discomfort during pumping, start by checking your primary pump:
- Are your flanges the correct size?
- Have you replaced your pump parts recently? (Especially your valves- they control the suction!)
- Is your motor still performing at full strength?
Whichever pump you choose, PLEASE remember to get sized for a well-fitting flange. During my last consultation, my client declined flange-sizing because the hospital lactation consultant sized her at a 21mm. At the end of our session, I persuaded her to get sized and it turns out that she could be using a 15mm. That’s a huge difference! You might have the best pump in the world, but if you are using the wrong flange size, you aren’t going to get the most out of your pumping sessions.
❤️ Final Thoughts: Do You Need Both?
For many moms, having both a primary and secondary breast pump is the perfect balance between supply protection and flexibility. If you are an exclusive pumper, I highly highly suggest having more than 1 pump.
Your primary pump keeps your milk supply strong.
Your secondary pump keeps your schedule flexible.
Plus, if your pump should stop working for any reason, having multiple pumps ensures that you always have a back-up, even if it’s your trusty manual pump. Understanding how and when to use each kind of pump can help you feel more confident and in control of your pumping journey — no matter where life takes you.
