This double pump set reduces pumping time by 50%, promotes milk production, and triggers milk flow more quickly. It includes two Ardo pump sets and is particularly suitable for intensive and prolonged use of an electric breast pump. The "Vacuum Seal" technology creates a 100% barrier against pathogens and contaminants in breast milk as well as in the breast pump from incoming breast milk. The set is made of high-quality, BPA-free polypropylene. Different breast shield sizes and the Optiflow massage insert are also available.
