A privileged partner : 50 years of experience in nuclear safety

More than 5,000 pumps in operation worldwide.

Rütschi has been a longtime partner in nuclear power plants construction for over 50 years. The origin of this activity dates back to the Beznau nuclear power plant construction in Switzerland in the 1960s according to ASME Boiler and Pressure Vessel code.

The significant development of the nuclear market in the 1970s accelerated the involvement of Rütschi with the build-up of the French nuclear program. This market development fostered the creation of our production unit in Mulhouse, France and developed our mastery of the RCC-M building code.

Today Rütschi offers the most extensive product range of centrifugal pumps for nuclear applications.


Increasing quality for even more safety.

To date, Rütschi has supplied a fleet over 5,000 pumps for various safety related and non-safety related circuits in more than 110 nuclear power plants around the world and is present on all kind of technologies.

We are also involved in the safety of new generation reactors. Rütschi is a key partner in the Post-Fukushima projects as well as in plants life-extension programs, by offering proven reliable technical solutions.

Our customer challenging projects have through these decades trusted Rütschi’s proven technologies and reliability.
