Nuclear Power Plants

Nuclear power plant operators worldwide place their trust in KSB pumps

Successful operation of a nuclear power station demands the highest standards of safety. For more than 40 years, KSB solutions have ensured safe and reliable processes in around 200 plants worldwide.

The greatest challenge for nuclear power plant operators: ensuring absolute safety

The key criterion for the nuclear energy sector is the fulfilment of the most stringent safety requirements. Pumps and valves must comply with international codes and standards and offer exceptional reliability to minimise downtime and repairs.

Minimising long-term operating costs is a further priority for power plant operators. This demands technology that works flawlessly at all times. And – especially important – a comprehensive range of services available around the clock.


Safety through competence – across the globe

Power plant operators are in safe hands with KSB, as our solutions comply with international codes and standards and meet the strictest quality assurance requirements. KSB products work absolutely reliably throughout the entire life cycle of a power plant – whether as cooling water pumps, reactor feed pumps or safety valves. This reduces downtime, minimises long-term life cycle costs, and improves performance.

Even in the event of decommissioning and beyond, operators are always on the safe side with KSB products. And they also benefit from comprehensive global service offerings available 24 hours a day.

All these services guarantee that power plants operate safely all over the world with KSB’s assistance – whether in Europe, Asia or America.


Performance you can rely on

KSB does not just manufacture pumps and valves. We also test them on site, examining aspects such as functional reliability, earthquake safety, noise emission and performance. Our facilities include a test bed for large pumps with 20 MW motors.

In addition, KSB products are tested at the factory on various test fields – including a specific test for reactor coolant pumps. And because the KSB plant in Frankenthal is ASME-certified and an ‘N Stamp Holder’, all ASME orders can be handled completely in-house.   

Materials can increase operational safety in nuclear power plants, and KSB uses the most advanced materials in its pumps and valves for this sector. These are also continuously tested and further developed with the aid of cutting-edge methods.

KSB test field

We can test boiler feed pumps at pressures of up to 500 bar and temperatures of up to 230 °C using our production-integrated test facility’s 20-megawatt motor.
