Spectra® - S2 Pro Hospital Grade Double Electric Breast Pump

The Spectra S2 Pro is a hospital-grade double electric breast pump designed for breastfeeding mothers who need powerful, consistent performance at home. Delivering up to 270mmHg of suction — the same standard used in hospital-grade equipment — the S2 Pro provides the strength needed to establish and maintain milk supply through regular pumping. The pump operates on AC power and features a two-phase system. Massage Mode offers 5 levels of gentle stimulation to initiate letdown, mimicking a baby's natural suckling rhythm. A single button press switches to Expression Mode, where suction strength and cycle speed can be independently adjusted to match each mother's comfort and output needs. The S2 Pro comes with breast flanges in two sizes — 24mm and 28mm — to accommodate a range of nipple sizes right out of the box. Like all Spectra pumps, the S2 Pro uses a closed-system design. The backflow protector creates a complete physical barrier between expressed breast milk and the pump's motor and internal components, preventing any backflow into the tubing or pump body. This protects against bacterial and mold contamination and keeps the motor performing reliably over time. All milk-contact parts are BPA and DEHP free. The LCD display with built-in auto-timer makes it easy to track session length and monitor pump settings at a glance. The pump operates at an ultra-quiet level suitable for use during nap time or overnight sessions, and the built-in night light allows for discreet low-light pumping without disturbing a sleeping baby. The S2 Pro supports both single and double pumping and is compatible with the full range of Spectra accessories and replacement parts.
