Check the Fit of the Flange
Using Your Breast Pump
The Advanced Single Electric Pump works with the Evenflo AdvancedFit™
Flange System. The Advanced Single Electric Pump comes with the Large
30.5mm base flange size and the Medium 28.0mm silicone flange insert.
Additional sizes are available separately for purchase, allowing you to find
your best fit.
The AdvancedFit™ Flange System available sizes include:
• X-Small = 21.0mm (insert)
• Large = 30.5mm (no insert)
• Small = 24.5mm (insert)
• X-Large = 33.0mm (insert)
• Medium = 28.0mm (insert)
• XX-Large = 36.0mm (no insert)
IMPORTANT:
• DO NOT use the flange insert if your nipple is larger than the center opening.
• Your breast may change over time. Should this occur, choose a different size
for maximum comfort.
• Included flange sizes may not fit all breast and nipple sizes, but
additional sizes can be purchased separately. If you are having issues
after trying all included sizes, please contact our Parent’s Ally Resource Center
for assistance.

To maximize your pumping results,
stimulate your let-down reflex by:
• Relaxing and thinking about your baby.
• Gently massaging your breasts, starting
nearest your ribs and working down
toward the nipple.
• Applying warm, moist compresses.
Continue until you can hand-express a
few drops of milk.
Now you should be ready to use your
pump.
For best results, hold the pump by the
flange
A
. Place the flange

gently
against your breast with your nipple cen-
tered in the flange tunnel. Press directly
against your breast to create a good seal.

Note: Pressing too hard can restrict milk flow in your breast and may break
the seal between the pump unit and the flange.

If holding by the pump unit
B
, do not
support the weight of your breast with
the pump. Press the flange directly against
the breast; do not scoop breast into the
flange. This may cause the pump unit to
disconnect from the flange assembly and
not work properly.
Correct Flange Size Vs. Too Small or Too Large
A proper flange size is needed for comfort and to maintain your milk supply. As your
flange size can change several times throughout your journey, ensure your pump has
multiple sizes available.
FLANGE TOO SMALL
While pumping, some
or all of your nipple rubs
against the sides of the
breast flange tunnel. Use
a larger size.
CORRECT FLANGE SIZE
While pumping, your nipple
should move freely in the
breast flange tunnel. You
should see space around the
nipple. A minimal amount
of your areola is drawn into
the tunnel with the nipple.
FLANGE TOO LARGE
While pumping, more
areola is drawn into the
breast flange with your
nipple. Your areola may
rub against the side of the
breast flange tunnel. Use
a smaller size.
