Case Study- From Liability to Reliability

Posted on

Our latest article in Pumps & Systems Magazine discusses a case where aging in‑line OH4 pumps were becoming a costly reliability risk after nearly three decades of operation.

This case study shows how a strategic retrofit to an API OH3 design dramatically improved bearing and seal reliability, reduced maintenance effort, and preserved the original footprint—all without disrupting operations. Discover how rethinking legacy equipment turned a chronic maintenance liability into a long‑term reliability win.

Case Study- Improving Reliability of Descale Pumps

Posted on

Our latest article in World Pumps Magazine discusses a case where advanced technology, targeted upgrades, and thinking outside the box helped a steel mill avoid costly downtime.

When facing repeated failures of their descale pumps, Hydro helped the mill salvage enough usable components from the failed pieces of equipment to return a fully functional, upgraded piece of equipment to service. By performing and in-depth root cause analysis and implementing material and design upgrades, the equipment has been transformed from a bad actor to a reliable piece of equipment.

Join Our Lecture | 2025 Turbo Pump Symposia

Hydro is proud to be presenting again at the 2025 Turbo Pump Symposia in Houston, TX! Join presenters Dr. Gary Dyson and Freddy Cardenas Linero as they discuss a case study where advanced engineering was used to dramatically increase flow of a shipping pump in an oil and gas terminal facility.

Wednesday, September 17, 2025 | 2:00 – 2:45pm | Room 370A

Centrifugal pumps are critical to fluid handling systems, but as operational demands evolve, optimizing performance becomes essential. This lecture will present a successful hydraulic re-rate of a propane shipping pump (P-1010) at Phoenix Park Gas Processors’ Hull facility in Texas, aiming to double railcar loading capacity without major system modifications. Instead of replacing the pump, a process requiring over 40 weeks of lead time and costly infrastructure changes, the project used a duplicate unit sourced from the aftermarket. It was reverse engineered, hydraulically redesigned, and optimized using CFD simulations to shift the Best Efficiency Point from 350 GPM to 800 GPM while reducing head by 60%.

The study highlights the importance of combining CFD analysis with mechanical evaluation to ensure reliable performance. It outlines a structured methodology from feasibility assessment to installation, including modeling, manufacturing, quality control, and commissioning. This project demonstrates how a targeted hydraulic re-rate can extend equipment life, increase throughput, and reduce energy use and capital costs, all while maintaining existing mechanical and system constraints.

The Hidden Costs of Cheap Repairs

Why Technical Expertise plays a Critical Role in Equipment Maintenance

As the industrial world becomes more competitive, reducing costs is key for maintaining an advantage in the marketplace. As such, many end users have become more cost-conscious when approaching equipment repair. In some services- where equipment is not complex and performance doesn’t affect process availability or quality- this strategy can provide some benefit. However, the short-term gain of a lower repair price often turns into long-term cost increases when a lack of engineering capability impacts equipment reliability and performance.

The importance of engaging with a facility that has strong engineering capabilities and subject matter expertise was proven during a series of boiler feed pump repairs for a Canadian biomass power plant. Like many biomass facilities, this plant had segmental ring boiler feed pumps, also commonly referred to as BB4 pumps. This is a complex design installed in a high energy, critical application, with numerous stacked and nested components that must be kept in alignment.

In this case, a small shop had completed several repairs that had resulted in high vibration and performance issues. These pumps were a legacy design that was no longer supported by the OEM and required engineering knowledge to properly refurbish and set the balance device. As such, it was important to find a repair partner that had a strong understanding of pump design. The plant worked with Hydro’s Scotford facility to bring these “bad actor” pumps back to optimal performance.

Strategies for Improving Life & Performance of Aging Equipment

Posted on

Many of our aging facilities are still using the pumps that were purchased and commissioned during plant construction. Despite the age of this equipment, effective maintenance strategies and upgrade opportunities can extend useful life for decades more. Older pumps are often more robust than current designs, which take advantage of new manufacturing technologies to reduce the raw materials needed for construction. However, vintage equipment has its downfalls as well. It is important to understand the challenges we face when operating and maintaining vintage equipment so that we can stay ahead of potential sources for decreased reliability.

These challenges were at the forefront of an improvement project undertaken by a Canadian pulp mill. Most pulp and paper mills in North America have been in operation for decades, and many are still running with the original equipment. This facility had several BB2-style makeup liquor pumps (MULP) that were experiencing a low mean-time-between-failures (MTBF). To increase pump life and reduce the risk of unexpected downtime, the pulp mill approached Hydro’s Scotford service center for support in identifying the root causes of degradation. Hydro Scotford combined a thorough inspection process with experience in upgraded designs and materials to bring the MULP system reliability back to an acceptable level and improve overall performance. The major focus points of this project – standardization, material upgrades, and improved tolerances – can be applied to aging installations in all industries.
