From its first storefront on Diversey Street in Chicago in 1969, Hydro has grown into an expansive service network that supports rotating equipment users worldwide. Our extensive footprint ensures that we can deliver our hallmark quality and exceptional customer service to clients across the globe.
Our geographic expansion has been accompanied by the growth of our engineering capabilities and our application knowledge. While all Hydro facilities are guided by the same processes and standards, we have also developed targeted capabilities, tooling, and experience in our individual locations to serve their local markets. This service base is complemented by our centralized global engineering division, with experts in disciplines such as hydraulic design, metallurgy, and vibration analysis and troubleshooting.
By leveraging a diversity of expertise and resources, we can cater to the unique needs of each customer, ensuring timely and effective solutions that uphold our high standards of excellence. Some examples of niche capabilities within our network that can be leveraged by Hydro’s customers include:
- Our clean room at HydroTex Deer Park
- Reciprocating pump repair, troubleshooting, and engineered upgrades
- High-capacity vertical pump repair and re-engineering at Hydro East
- Nuclear safety-related and code repair, parts, and new units at the HydroAire Madison St facility
- Access to expedited cast parts through Hydro Parts Solutions
- 5-axis machining, including milled vane impellers, at HydroTex Dynamics
- Oil field services equipment through Hydro Middle East
Our growth has strengthened—not diminished—our commitment to local service excellence. Each service center combines on-site, dedicated engineering resources with established local supplier networks to deliver timely, effective support. We believe that communication is the cornerstone of successful collaboration, and we work hard to foster a culture of transparency and engagement.

One of the key milestones in HydroTex Dynamics’ development was the time spent with Dr. Elemer Makay in the late 1980s and early 1990s perfecting the radial gap modifications (commonly known as A Gap, B Gap, and C Gap) on multistage diffuser-style pumps. Dr. Makay was a pioneer in battling impact loading and discharge recirculation in multistage pumps, failure modes that had historically caused high vibration, premature wear, and shaft failures for this equipment. He partnered with Jim Shaffer, founding partner of HydroTex Dynamics, in applying modifications that would combat these failure modes to drastically improve mean-time-between-repairs.
Under the leadership of HydroTex Dynamics’ VP, Pete Erickson, they have continued to build upon this foundation by investing in advanced tooling, developing experienced shop talent, establishing a responsive field service unit, and fostering deep customer relationships grounded in trust and transparency. In 1995, they purchased the Pacific BFI line of BB5 pumps for North America, adding to their experience base in high energy, multistage pumps. They have on-site capability to perform 5-axis machining and can supply milled vane impellers with an industry leading turnaround time. While not currently certified, they are ISO compliant and follow all ISO practices.
Performance testing in a controlled environment is an important tool for pump designers and users alike. Understanding how the pump will react hydraulically and mechanically throughout the full range of operation enables improved equipment reliability, optimized efficiency, and reduced operating and maintenance costs.
To support end users in understanding equipment health and performance, Hydro built its Certified Performance Test Lab at the HydroAire 40th Street service center in Chicago. Our test lab was the first to be certified by the Hydraulic Institute’s
