Size Guide

Pack of 2 replacement diaphragms for use in your universal backflow protector. 


The diaphragms in your backflow protector need regular replacement. Expect to replace diaphragms every 6 months of light use, i.e. if you're pumping just a few times a week, up to every month if you're pumping exclusively. 

  • Compatible with the Universal Backflow Protectors. These are the backflow protectors that ship with your Genie Plus :).
  • Not compatible with the Liquid Kit.

All Pumpables parts in contact with your milk are free from BPA, phthalates and other nasties.

    Great product

    These diaphragms fit my Spectra pump parts really well and gave me a boost in output.

    Bought this new seal diaphragms didn’t realise my back flow protector is old model. Unable to use it because its not compatible but pumpables kind enough send me the new back flow protector with no charge. Thank you Pumpables!

    Always consider replacing your diaphragms to improve your pumps performance! A good way to tell if the diaphragm needs replacement is to compare against a fresh set, the older ones have much less defined edges and flex with less resistance
