Facility Spotlight: HydroTex Dynamics

HydroTex Dynamics was founded in 1979 to meet a growing need for aftermarket service in the Houston area. By focusing on quality workmanship and cultivating strong relationships with customers, HydroTex Dynamics has become recognized as a premiere service location not only in the Houston area, but across the US. As an independent, they have expertise across OEMs and applications, with a strong focus on the power market and high-energy multistage pumps. The experience base and library of upgrades they have built support customers in increasing the reliability and life of critical equipment.

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.

The radial gap modifications were applied to high energy boiler feed pumps across several Texas utilities with great success and are now regarded as a standard design for new boiler feed pumps. HydroTex Dynamics’ experience working with Dr. Makay on this modification provided them not only with an important understanding of factors that affect pump reliability, it also inspired a culture that paid attention to the many small details that add up to a smoothly running piece of equipment. This understanding has driven the service center’s high standards, including strict tolerances for critical geometries and balance, best-in-class assembly procedures, including a pit for assembling multi-stage pumps vertically, and an in-depth dimensional analysis that is the crucial first step in establishing axial centerline compatibility of every impeller within its respective diffuser.

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.

One of the greatest strengths of HydroTex Dynamics is its people. The majority of workers in the shop have been with HydroTex between 15 and 30 years. Their hard-won experience and commitment to excellence is a cornerstone of the superior reputation that the shop has earned. By prioritizing communication and understanding each customer’s needs, HydroTex Dynamics delivers on their promise to provide one source of total support to pump users.

Strategies for Improving Life & Performance of Aging Equipment

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.

Modifying Existing Equipment to Maintain Operational Standards

Many aging manufacturing facilities have witnessed changes in market demand that have altered their product slate and capacity. These changing system demands often cause equipment that was previously well-sized for the application to run significantly away from the operating range where peak efficiency and reliability are achieved. Running in this mode drives up the life cycle cost of equipment due to short maintenance cycles and wasted energy. In cases where reliability is severely compromised, equipment operating costs can also be accompanied by risk to production due to mid-cycle failures and unavailability of equipment.

To maintain safe, reliable and cost-effective operation, it is important to ensure pump systems are optimized. When approached with the need to optimize a pump system, many end users will look to purchase new equipment for the changed demand. This can be a costly and time-intensive endeavor, as new equipment installation is often accompanied by baseplate and piping modifications that require the system to be taken offline. In contrast, modifying the existing equipment to meet the new system needs provides a custom solution that maintains the original footprint, can be completed on a more aggressive timeline and often provides a more custom fit to the system.

The decision to perform one such modification was made by a major Gulf Coast oil refinery that was running at a significantly lower flow than the original system demand. The site reliability team worked with Hydro to design and implement an extreme downrating of the existing equipment. The result was an optimized system that improved reliability of not only the pump, but other affected system components.

White Paper: Performance Prediction for the Aftermarket

Pumps are often expected to run at low flows and on many occasions can spend their entire operating lives there. It is important to understand the complex behavior of fluid and how that affects performance and reliability so that modifications can be made to achieve optimal performance in these challenging conditions.

By combining reverse engineered data, analytical tools and engineering expertise, a comprehensive approach can be developed to understand and modify hydraulic performance. This process allows pumping equipment to function exactly as required by the system that it fits within.
