1. A major customer was preparing to reopen a refinery. However, many of the critical pumps required excessive repair and inspection after prolonged storage, and being exposed to the elements.

    Hydro was able to service all the pumps, but before placing them into service, the customer opted for performance testing and validation to ensure the units would meet the refinery's requirements and production needs.

  2. A power utility was experiencing problems with many of its multistage ring section (BB4) pumps in several of their plants.

    In this case, Hydro was able to develop a long-term engineering solution for the unit in focus, and with the help of Hydro's independent test lab in Chicago, Illinois, they were able to provide performance testing and verification of the upgrades prior to installation.

  3. A major oil refinery was having vibration issues on two of their 10-stage BB5 pumps. Both pumps had a history of high vane pass frequency vibration, particularly at the inboard bearing housing.

    The refinery reliability engineers suspected that the high vane pass frequency was due to a coincident natural frequency in the Original Equipment Manufacturer (OEM) structural design of the inboard housing, thus creating a critical speed at the operating speed of the pump.

    In this video, Jeff Giroux of HydroAire 40th Street and Ares Panagoulias of Hydro's test lab team, discuss the historic resonance problems and provide a bearing housing resonance test in conjunction with an API 610 11th Edition performance test to further identify the severity of the vibration and ultimately provide an engineering upgrade.

  4. Bob Jennings of Hydro, Inc. discusses how a major steel manufacturer's five vintage descaling pumps were consuming too much power and not producing enough output.

    Many pumps in operation today were designed and manufactured decades ago. Due to an increase in energy demand, these pumps are often operating at higher flows, farther from their best efficiency point. As a result, the designs and hydraulic characteristics many no longer be as effective.

    Learn how an in-depth engineering analysis led to a full refurbishment saving a steel plant millions per year in downtime, repairs, and maintenance.

  5. Hydro was contacted by a major oil refinery to rerate and upgrade a reactor charge pump for a relocated processing unit.

    In its previous installation, the pump had a history of persistent high vane pass vibration despite several attempts to modify the pump and support pedestals by the pump’s original equipment manufacturer (OEM). Due to the reduced feed rate to the unit at the new location, the pump required a hydraulic rerate in addition to the need for reduced vibration.

Many pumps in operation today were designed and manufactured many decades ago. Due to an increase in energy demand, these pumps are operating at higher flows, farther from their best efficiency point. As a result, the original impeller design and its hydraulic characteristics many no longer be as effective for the plant’s new requirements.
