Understanding Primary Pumps: What You Need to Know
If you've spent any time in the world of pumping, you've probably come across the term primary pump. But what exactly does it mean? Unlike other standardized terms in breastfeeding and pumping, "primary pump" does not have one clear definition. Instead, it gets used in different ways depending on the context.
In this post, we’re going to break down what a primary pump is, how the term is used, and how you can apply this knowledge to your own pumping journey.
What is a Primary Pump?
At its core, a primary pump is a breast pump that is intended to be used routinely and frequently. This means it’s designed for multiple pumping sessions per day and has a proven track record of supporting and maintaining milk supply.
These pumps are tools that work reliably for many parents who are exclusively pumping, pumping to increase supply, or pumping to maintain their supply over an extended period.
Key Characteristics of a Primary Pump
Durable Motor – A pump with a long-lasting, strong motor capable of sustaining multiple pumping sessions a day.
Proven Track Record – It must be widely recognized as an effective tool for milk production.
Customizable Settings – The ability to adjust suction strength and cycle speed to fit different users' needs.
Because every body responds differently to breast pumps, the best primary pumps allow for customization to match individual comfort and efficiency.
Examples of Primary Pumps
Many breast pumps fall into the primary pump category. Some of the most commonly recognized primary pumps include:
Spectra S1 & S2 – The Spectra S1 (blue, with a battery) and S2 (pink, no battery) are some of the most widely used primary pumps. They have durable motors, high customizability, and are well-known for their reliability.
Spectra Synergy Gold – A newer hospital-grade offering from Spectra with independent control of left and right suction.
Unimom Opera – A strong hospital-grade pump with dual-motor technology and extensive customization options.
Medela Symphony – A hospital-grade pump often used in clinical settings and by exclusive pumpers for its strong motor and reliability.
Limerick Pumps – A unique hospital-grade pump with soft silicone cups and a gentle yet effective suction pattern.
Ameda Platinum – A hospital-grade pump with a well-established reputation for sustaining milk supply in exclusive pumpers.
Portable Pumps That Are Sometimes Considered Primary Pumps
While portable pumps are not typically classified as primary pumps, two models frequently function as primary pumps for many users:
BabyBuddha 2.0
Pumpables Genie Advanced
Both of these pumps have shorter motor lifespans (under 1,000 hours, compared to the Spectra’s 1,500+ hours). However, they still work well for many exclusively pumping parents because of their:
Effective suction strength and cycling ability
Adjustable settings
Ability to be used with different flange and tubing setups
Even though they don’t technically meet the definition of a full-size, long-life primary pump, their effectiveness and widespread use allow them to function as one.
Pumps That Are Not Considered Primary Pumps
Some pumps, even with a wide range of settings, are not effective for long-term exclusive pumping. This is because they do not drive milk supply effectively for most users.
For example:
Most Wearable Pumps – Pumps like the Elvie and Willow are designed for convenience, not as primary workhorse pumps. While they can be useful for certain situations, they typically do not sustain supply well over time.
Why Customizability Matters
One of the biggest factors that make a pump a true primary pump is the ability to adjust both suction strength and speed (cycle settings).
Some people respond best to:
Low suction, high speed
High suction, low speed
A combination of both at different times
A primary pump must have the flexibility to accommodate these differences.
While some portable pumps (like the BabyBuddha 2.0 and Pumpables Genie Advanced) don’t have as many settings as full-size pumps, they compensate by allowing users to modify their setup with different parts. This ability to tweak the system makes them viable options for many exclusively pumping parents.
How to Choose a Primary Pump for Your Needs
If you're a first-time pumping parent or planning to exclusively pump, it's important to start with a strong, reliable pump that is known to support supply.
Best Choice for a New Pumping Parent
Spectra S1 or S2
Spectra Synergy Gold
Unimom Opera
Medela Symphony
Ameda Platinum
Limerick Pumps
These pumps are known for their durability and effectiveness in establishing and maintaining milk supply.
When You Might Consider a Portable Primary Pump
If you need a more portable option but still want something strong (e.g., BabyBuddha 2.0 or Pumpables Genie Advanced).
If you already know your body responds well to these types of pumps.
If you need a backup option for times when a full-size pump is inconvenient.
What If a Primary Pump Doesn’t Work for You?
Even if a pump is classified as a primary pump, not every pump will work for every body. If a pump does not work for you—meaning it does not effectively remove milk—it can actually harm your supply.
This is why there is no single "best" breast pump. The best pump is the one that works for your body.
If you’re struggling with your pump, consider:
Adjusting the settings (changing cycle speed and suction levels).
Trying different flange sizes or alternative parts.
Switching to a different pump that better suits your body’s needs.
Final Thoughts
A primary pump is simply a pump that is capable of driving and maintaining a milk supply when used routinely. While some portable pumps can function as primary pumps, the best choice for new or exclusively pumping parents is usually a full-size, durable pump with a strong motor and adjustable settings.
If you're looking for a primary pump, focus on choosing a proven, strong performer to ensure you have the best tool for your pumping journey.
Happy pumping! 🚼💛
