Ingersoll Rand 6x13 DA 3 3-stage
Serving an end user in the oil and gas industry, Hydro Scotford repaired and upgraded this pump with composite materials. The pump was also reverse engineered so a future hydraulic re-rate could be performed.
IDP 16QL Double Suction Vertical
This IDP vertical pump experienced repeated failures due to chemical erosion. Hydro Scotford redesigned and upgraded this pump during the rebuild process to increase the pump’s resistance to the abrasive service and improve mean-time-between-repair.
Byron Jackson 6-stage Boiler Feed
When this boiler feed pump failed due to a dry-run event at a power plant, Hydro upgraded the pump with composite wear materials. Composite materials have been proven to increase efficiency and lengthen the life of boiler feed pumps. Non-galling characteristics result in longer run times and safer pump operation. Lower clearances reduce internal pump recirculation, providing equal flow with reduced use of horsepower, resulting in improved efficiency and reduced operating costs. Rotor stability is improved and vibration is reduced which extends the life of bearings and mechanical seals.
Byron Jackson 20 MQH 3-stage
Hydro Scotford upgraded this vertical condensate return pump with composite line bushings to improve rotor stability and extend service life.
Johnston 3-stage River Water Pump
A power plant sent their river water pump to Hydro Scotford for repair. Hydro Scotford improved the fits and tolerances as well as implemented upgrades to reduce vibration, increase bearing life, reduce power consumption and extend the pump's mean-time-between-repair.
Ahlstrom LRS 2-stage
This pump, from a kraft pulp mill, processed black liquor. After performing a thorough inspection, Hydro Scotford recommended a repair plan that included machining new wear rings without slots to prevent abrasive materials from damaging the case and minimizing wear behind the casing wear rings. Hydro also designed and machined a 4-bolt split packing gland follower to help maintain alignment of the packing gland follower with the stuffing box. This engineered pump repair enabled the pump to process more than 1200 tons of material per day.
Ahlstrom 7LFG-5 Ring Segment Pump
This pump, which was in high-pressure shower water service at a pulp and paper mill, was prone to failure from dry-run events. Hydro Scotford provided engineered pump upgrades during the repair process which would enable to pump to produce the required flow and head during short dry-run events.
