A Powerful Partnership
Proven Experience

This powerful partnership enables Hydro, Inc. to provide top-quality services to Hydro Richier according to project requirements. This combined engineering expertise, coupled with the latest technology and a global network, allows Hydro Richier to support our customers with top-quality services.

Since 1969, Hydro, Inc. has offered a range of pump rebuilding and engineering services to the power generation industry. Hydro's Quality Assurance Program complies with 10 CFR Part 50, Appendix B, N299, and ASME Section III. The Program has been audited by the Nuclear Procurement Issues Committee (NUPIC).

Engineering Upgrades

Mechanical upgrades (i.e., precision split rings, interference fits, establishing concentricities, establishing perpendicularities), metallurgical upgrades, and composite materials.


Hydraulic analysis, computational fluid dynamics, rotor dynamics, and qualification under accidental conditions.

Reverse Engineering

Examination, testing, and analysis of critical components to capture all of the parameters and attributes necessary to provide manufacturing, repair, or modifications.

For this project, the casing of a critical charging pump at a European nuclear plant had been over-pressurized and needed to be refurbished. In this case, Hydro executed an innovative solution by machining the casing in the contaminated state and developed a creative method to guarantee a proper fit-up when the casing repair was completed.

Hydro Richier has the capability and experience to reverse engineer and replicate parts for a wide range of equipment. Using our coordinate measuring machine technology, we can efficiently scan a part and digitize the dimensional data. The digital model created is used to machine the new component, which is then scanned using the same technology to confirm adherence to the original part’s dimensions.

Contaminated Repair Services

Quality inspection, forensics, troubleshooting, rotor centralization, and rotor balancing.

Pump Performance Testing

State-of-the-art data collection systems capable of testing hydraulic performance, vibration, temperature, power, and other factors for a variety of pumps and applications.

Field Service

Pump installation and start-up, field machining, turnkey services, project management, vibration analysis, and onsite troubleshooting.

Hydro, Inc.
A European Partner

When it comes to nuclear business cases, Hydro Richier, in partnership with Hydro's global network of dedicated aftermarket pump service centers, provides comprehensive engineering services for the nuclear industry to repair critical equipment, analyze existing performance, and troubleshoot existing issues.

Reverse engineering contaminated safety-related pump parts at a nuclear power plant.

A nuclear plant in Europe, struggling with poor quality and delivery from the OEM, requested Hydro, Inc. to reverse engineer and supply a pump rotor.

A European nuclear plant was struggling with delivery and quality issues, and had requested Hydro, Inc. to reverse engineer and supply new emergency service water pump parts.

Hydro, Inc. provided reverse engineering for several obsolete ASME safety-related pumps for a nuclear power plant.

Hydro Richier
Success Story

In this case, Hydro Richier fully machined a large circulating water pump's impeller for a nuclear power station. In partnering with Hydro, Inc. who provided reverse engineering of the components, Hydro Richier executed 100% of the procurement process, coordinated the casting through a European foundry, and completed all the machining for the project's scope.



With over 60 years of combined experience, Hydro Richier’s know-how extends from the manufacturing of technical and complex parts of small and large dimensions to the global offerings for the production of complete assemblies. Hydro Richier offers a turnkey solution: a design office including the analysis and design projects, and dedicated teams overseeing hydraulic, pneumatic, electrical integration, automation, programming, assembly, debugging, and installation on site.

Certified ISO 9001, ISO 14001, and OHSAS 18001, Hydro Richier’s quality system guarantees us rigor while maintaining the flexibility of an SME. The complementarity of Hydro Richier’s know-how allows them to be your partner, regardless of your project or scope, including the European markets.
