In this blog, we have already talked about tons of breast pumps – whether they’re electric, manual, or hospital grade. One of the most famous brands of breast pumps is Medela, and we have written a comparison post about it versus another famous brand, the Ameda. We all know a breast pump will not work properly without good and functional parts. That is why this post will serve as a guide for all the mothers out there who wants to know about the different Medela breast pump parts.

If you’ve got one of the Medela breast pumps then you’ve visited the right place. Whether you are an exclusively pumping mom or just pumping to keep your milk supply up, it is always essential to get the right breast pump parts and replace them immediately when needed. You have to do occasional breast pump check-up and parts replacement. So that you can avoid further damage and make your Medela breast pump last longer.

Most Medela breast pump parts are compatible with the Medela breast pumps. There may be a few exceptions when it comes to the hospital grade ones, and it will be indicated below.

What are the different parts of a breast pump

Breast shields

Some mothers refer breast shields as flanges. It is a nipple-shaped shield that is worn over the areola and nipple during breastfeeding. Breast shields have a hole or an opening at the nipple side to allow the expressed breast milk to pass through. Finding and using the right breast shield size is very important.

Tubing

Valves

Membranes

The membranes, as mentioned above, is fitted and attached to the valve. Made of small flexible plastic parts, these membranes create suction. It is important that you replace a membrane that’s worn out. A worn out or damaged membrane will greatly affect the pumping performance of your breast pump.

Connectors

This is also an important part of the breast pump. The connectors work to connect the tubing, PersonalFit breast shields, and the bottle. They can attach to all breast shield sizes and compatible with most Medela breast pumps. Breast shields and connectors are sold separately most of time.

Collection and storage

There are bottles or storage bags that are specific only for milk collection. But there are also feeding bottles that are compatible with the breast pump so that you can collect and feed right away.

Looking for a breast shield to use with your Medela pump should not be a challenge since all the Medela pumps are compatible with the breast shields by Medela as well. The standard breast shields that come with your breast pump upon purchase are medium-sized. But if you want to be able to select your size, then no need to worry since they have the PersonalFit line. These PersonalFit ones allow you to choose the best size for you.

The Medela PersonalFit breast shields provide customized and more options for optimum comfort and maximum milk expression. Take note that the PersonalFit and Standard breast shields require the valve and membrane.

If you are not sure about your size and is still confused on how to choose. Don’t worry since we have some helpful tips for you:
