Year Founded:

Our mission is to work hand-in-hand with our valued customers to optimize the performance and reliability of their pumping systems by evaluating and understanding root causes of pump degradation or failure and by providing unbiased engineering analysis, quality workmanship, and responsive field service for improved plant operation.

The company tests various types of pumps, including axially split between bearings, radially split between bearings, over hung cantilever style, multi-stage barrel, vertical turbine, vertical can style, boiler circulating, and submersible pumps. It serves power generation, nuclear power generation, petroleum, steel, pulp and paper, municipal, and general industries.


Formed in 1969 by a small group of pump engineers with its first service center in Chicago, Hydro is now the largest independent pump rebuilder with service centers throughout the world.

Our mission was developed in the mid 1980's when we realized that as an independent pump rebuilding company, we had a unique capability of understanding the different designs and materials employed by the various OEM's as well as their successes or failures in specific applications and operating environments. Based on this data and experience, Hydro is in an excellent position to improve the original designs for their intended service.

Our high rate of repeat business is a testimonial to the performance improvements we have achieved in the field. Our independent and unbiased engineering approach enables us to recommend best in class design improvements based on the inspection data and our extensive empirical database.

Each of the Hydro companies initially started as a small business with a core group of dedicated individuals, working closely together to successfully build the business. These initial experiences encourage close working relationships because the strength of the team depends on the commitment of each individual.

As we have continued to grow, we have made a special effort to retain our 'family' culture. We recognize the importance that each individual plays in our day-to-day achievements as well as in our long-term growth. We value loyalty and commitment and these qualities play an important role in our philosophy and culture.
