Ardo Breast Pumps

Nestled among lush green meadows, lakes, and mountains is Unterägeri, Switzerland, home to the Ardo medical head office. This picturesque setting is where all of Ardo’s breast pumps are meticulously assembled by hand. In the late 1960s and 1970s, Ardo founder, Werner Kraehenbuehl, co-founded the world’s first breast pump company and brought the first electric breast pump from Switzerland to the United States. Today, Ardo celebrates 25 years since it was founded by Werner, the pioneer of electric breast pumps.

Still family-owned and family-run in second generation, Ardo is a global company providing moms with breast feeding support, products, and accessories in more than 50 countries. Ardo is the leading manufacturer of true hospital and hospital-grade pumps, with more than 200 hospitals using Ardo hospital pumps, and the number is growing daily.


With the Calypso pump, moms can quickly and easily assemble and disassemble their breast pump and effortlessly toggle the vacuum strength and cycle buttons to find their perfect setting.

Lightweight & Portable

Weighing less than a pound, the Ardo Calypso pump is so lightweight that it can be held up with just a pinky! The pump can be discretely carried in a purse as it is the same length as a paper-back book.

Battery Operated

Pump anytime, anywhere, even during sustained power outages. If a pump session is delayed and milk is not removed in a timely manner, like during a power outage, moms may suffer from adverse effects such as pain, engorgement, and plugged ducts (which may lead to mastitis). The Ardo Calypso electric breast pump is powered by AA batteries, in addition to a regular power adapter, or the optional car adapter.

Quietest Pump on the Market

Noise tests show that Calypso is the quietest breast pump! The Calypso is the quietest of all tested electric breast pumps. In comparison with many other commercially available pumps, it is only perceived to be half as loud, but it is still powerful.
