Adopt a Higher Standard

Hydro Adopt a Higher Standard

Adopt a Higher Standard

Enhancing performance and extending product lifespan doesn’t necessarily require major design or operational overhauls. Often, modest adjustments to the standards and procedures employed in refurbishment and assembly can yield significant benefits.

Hydro Adopt a Higher Standard (1)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. To learn more about the importance of maintaining design clearances, read this Hydro Learning Hub white paper on the subject.

Hydro Adopt a Higher Standard (1)Another improvement that is standard at Hydro for repairs of multistage barrel (BB5) pumps is a dimensional analysis to identify relative centerlines of all impellers to their respective diffusers. This process and the resulting actions to ensure centerline compatibility at each stage are essential in prolonging equipment life and counteracting latent failure mechanisms.

By adhering to stricter tolerances, requiring robust process documentation, and never cutting corners, Hydro’s rebuild process results in greater reliability and increased mean-time-between-repairs. This level of quality ensures a safer work environment for our end user customers, reduces waste by decreasing the frequency of maintenance cycles, and lowers overall cost of ownership.
