Breast Pump Spare Parts

We often get calls from worried mums who need a new part for their breast pump.... perhaps their puppy chewed it, or boiled dry when sterilizing.    It happens all the time - so don't worry if it has happened to you.    We try to keep all these breast pump spare parts in stock because you'll need it in a hurry so you can keep pumping.    We carry parts for all pump models of Medela, Unimom and Avent.  But we know it gets confusing about which piece for which model - you can shop by "Pump Type" on the images below,  or by individual piece if you match the picture or know its name.       *TIP often it's the tiny little white valve and membrane that need replacing - as these control the whole suction performance of your pump.   

If you’re not sure what you need, simply contact us and we’ll help get the breast pump spare parts.
