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.
