When buying a Mumilk Pump, please note that you will need to replace the silicone parts overtime. Our recommendations are:

For The Original and PRO: Depending on the frequency of your pumping sessions, you may look at replacing: the diaphragm every 6 to 8 weeks; the valve every 4 to 5 weeks; the flange every 5 months

For the Ella: Depending on the frequency of your pumping sessions, you may look at replacing the valve, flange and diaphragm every 3 months.

Every Pump we sell comes with a 24mm or 27mm Flange. 

In the event where you initially purchased the wrong size or you need any spare breast pump parts, you can get them here. 

The Mumilk flanges and parts are BPA free and made of food-grade silicone.

Easy to use, wash and sterilize. 

To get the right size, follow the below instructions

While waiting for the parts to dry or sterilised it's good to have an extra set of "the lot." Love that I can easily purchase specific parts to replace what's needed for the Ella.

Sooooo good to have spare parts for express feeding my newborn

Product yet to arrive

Unfortunately these parts have yet to arrive which is disappointing as I'm an exclusive pumper and I'm reliant upon my breastpumps working at their best. The ones I did have certainly worked well so I have no doubt on the quality just disappointed with how long it is taking to receive.

Good quality!

The absolute best!

I am never one to write reviews however I thought I would share my experience.
I am express breast feeding my now 7 month old and I am so impressed. Without these wearables I would have given up EBF months ago. They have been super reliable, the battery lasts my all day (pumping 4 times a day). Only now am I looking at ordering spare parts for them.
I recommend these to every new mum. The best!
