A dependable source of quality parts supply is critical to maintain safe, reliable, and profitable operation of industrial facilities. However, aging equipment and pressure on the global supply chain have created a challenging environment in the replacement parts.

Obsolescence and loss of supplier experience have resulted in many plants rethinking the idea that the original equipment manufacturer (OEM) should be the go-to source for parts supply. Consolidation of OEMs and retirement and down-sizing on the supplier side have led to loss of capability, compromised quality, and slower response times. Ordering parts through the OEM is also a highly transactional process that rarely engages engineering. Without engineering involvement, there is no opportunity to determine if new technology or design improvements are available that can improve the reliability of the component.
Hydro helps end users meet the challenges of obsolescence with hard-earned reverse engineering expertise, an extensive library of parts drawings across OEMs, a global engineering network, and a dedicated parts division that delivers industry-leading turnaround times for cast components.
When sourcing an alternative for quality parts, it is important to understand that reverse engineering goes beyond simple replication and must engage an experienced engineering team. Advanced technologies can help significantly in the process of reverse engineering critical parts, but relying on these technologies alone is not enough to ensure proper design and manufacture. Geometry, metallurgy, hardness, tolerances, and coatings should all be considered and they add to the complexity of the reverse engineering process. Reproducing the part without reviewing the hydraulic, mechanical, and material characteristics of the component can lead to incorrect geometry or failure of the part when placed in service.

Hydro’s reverse engineering procedures ensure that a comprehensive engineering review is completed during the reverse engineering process. We are also able to leverage our library of known failure mechanisms and proven solutions to improve component design and performance.

Many pump applications experience ongoing vibration and reliability issues; aging installations are also seeing margins between operation and resonant conditions eroding and previously reliable equipment being pulled into problems. The root cause of these problems is often resonance, a condition that is often misdiagnosed and commonly goes undiagnosed, resulting in persistent high amplitude vibration issues for long periods of time. Structural resonance typically results in highly directional vibration and increased amplitudes that can be difficult to resolve without the proper engineering approach. Fortunately, technology has developed to diagnose resonance and develop effective solutions without resorting to costly trial-and-error methods.

Many OEMs focus on the initial pump design and providing a higher peak efficiency. While this can provide energy savings, it misses some of the greatest gains available. With our history in developing solutions for the aftermarket, Hydro approaches energy efficiency differently. Our unique experience as a brand-agnostic company focused on end users’ existing installed equipment has provided us with insight into improving equipment performance by understanding how it operates as a part of the greater system. This has allowed us to provide significant energy savings for our partners, as shown in successful cases such as
Hydro’s Energy Edge program takes advantage of our in-house engineering, field testing, remanufacturing, and parts capabilities to provide an end-to-end solution to improve energy usage and reliability. The process starts with getting the necessary design and operation data to perform a comprehensive analysis of current performance and identify opportunities for improvement. Depending on the findings, solutions can range from system operations recommendations to hydraulic modifications to a completely redesigned drop-in replacement. By providing a custom solution instead of an off-the-shelf replacement, Hydro not only optimizes performance, but minimizes cost, lead time, and risk by ensuring that the solutions fits into the existing equipment footprint.
Hydro specifies machining and fit-up tolerances that often exceed the required industry standards and are best-in-class for the pump industry. Taking the extra time to meet more stringent tolerances ensures better concentricity and parallelism of critical components, reducing the risk of contact between the rotating and stationary elements during operation. Reducing component contact will result in reduced vibration and reduce the rate of wear for close clearance components. Maintaining design clearances greatly contributes to longer mean-time-between-repairs by providing greater stiffness and damping to the rotating assembly and reducing internal recirculation, which in turn affects performance and efficiency.
