The mamivac Sensitive-CFH breastpump from KaWeCo has mamivac® 2-phase technology that simulates the baby’s sucking.

• Continuously adjustable vacuum strength, freely selectable pumping interval
• No suction loss with double pumping
• Gentle, hygienic and silent operation guaranteed
• Practical stand for mobile use in clinics
• With rechargeable batteries (available separately) ready for use immediately and everywhere
• Optional DC or AC power supply
• Integrated dual bottle holder

With the mamivac® 2-phase technology, breast milk can be expressed as gently and naturally as ever possible. The continuously adjustable phases consist of a stimulation phase and an expressing phase. The expressing process is not an automated sequence of a programme, but allows for an individual adjustment of suction strength and cycle speed to the individual needs of nursing mothers and the flow of milk.
