The Rumble Tuff Serene Express is a double electric breast pump which combines the effectiveness of a hospital-grade pump with the convenience of a portable pump. It uses a closed-system diaphragm which prevents milk from coming in contact with the tubing or motor. This lightweight pump weighs less than 1 pound, yet it is durable and dependable enough for daily pumping. 

With 2 Expression Programs, and 8 vacuum suction levels, the Serene Express can be easily customized to match your baby's nursing habits. The vacuum suction level can be adjusted independent of the Expression Program cycle. The 2 Expression Programs, Swift Expression, and Natural Expression are designed to mimic the way a baby nurses. The Swift Expression is the fast and shallow pattern that imitates the nursing pattern of an infant or smaller baby. The Natural Expression imitates the long and deep suckling of an older baby.

You can easily toggle between the Expression Programs with the Expression Button. Suction is easily adjusted by turning the Vacuum Adjusting Wheel. All changes are gradual to keep you comfortable while pumping.

The Serene Express is built with the innovative Memory ("M") button which can be programmed to remember your favorite pumping patterns and recall it for your future pumping sessions. Press and hold the "M" button to store your Expression setting, then press the button at your next pump session to recall your Expression setting.

The pump also features an easy-to-read LCD display, user-friendly controls, a clock, and an alarm to remind you of your next pumping session. It can be electric-powered, battery operated, or converted into a manual pump (Manual Pump Diaphragm Kit included).

The Serene Express Duo Electric Breast Pump comes with a 120-day warranty and a 1-year extended warranty for the pump motor (wearable accessories excluded). Warranty information can be found in the User Manual.

BPA free.
