Hydro South Basic Hydraulics Training (Seminar)

Join Hydro South for a one-day Basic Hydraulics training seminar. Presented by Hydro’s Bob Jennings, this course will cover basic pump design, pump and system curves, NPSH, and other fundamentals that pump owners need to know for reliable operation.

Circulating Water Pump Repair & Refurbishment

A major utility company had a Foster Wheeler 60 DF horizontal split case circulating water pump that required repair. They decided to complete the refurbishment during a 14-day unit outage by using the Hydro South service center. The plant had a spare impeller, shaft, and shaft sleeves in inventory. The availability of spare parts usually facilitates an efficient and trouble-free repair. Unfortunately, it was discovered that the parts available were not properly designed for use in the existing pump. Continue reading

Throwback: Expedited Vertical Pump Repair & Engineered Upgrade

A critical vertical pump for a 750 MW unit was sent to Hydro South in mid-December 2012 for inspection and repair. The massive pump weighed more than 66,000 lbs. and was 32 feet long and 12 feet tall. When the pump was disassembled, Hydro South’s engineers discovered that a large 42” x 68” section of the discharge elbow was broken, allowing direct flow to bypass the turning section and flow directly into the stuffing box area.

The discharge elbow was made of casted cast iron and could not be welded. A replacement of this size would take around eight months to order and receive. Continue reading

Hydro South Tests Nuclear Power Vertical Condensate Pump at Test Lab

Hydro South recently completed the overhaul of a Condensate pump at its facility outside of Atlanta, GA. This pump is a vertical can-type, motor-driven centrifugal condensate pump installed at a nuclear power facility in the Southeastern US. The condensate system has three identical pumps that operate in parallel (with a maximum of two pumps normally in service and an installed spare).

The pumps are designed to operate continuously for the normal 18-month fuel cycle with no maintenance attention. Because the condensate system is critical to plant operation, it is imperative to verify the performance of the pump before getting it back in service. Continue reading
