Nordlaks is a Norwegian totally built-in company that produces, processes, and sells Atlantic salmon and rainbow trout worldwide. It has just lately accomplished the building of a model new smolt facility for fish as much as 1 pound at Innhavet in Hamarøy municipality. This RAS (recirculating aquaculture system) fish farm is the most important of its type in Norway, with a particular give consideration to smolt welfare. The land-based facility has state-of-the-art equipment for optimal biosecurity and sustainability. At the guts of the RAS process, all recirculation pumps had been provided by Sulzer.
Fifty AHLSTAR and BE recirculation pumps (continuous duty) in water therapy loops. The dry-installed single-stage overhung pumps are geared up with semi-open impellers and single mechanical seals.
Five VUPX-0402 (602,312 gallons per hour at 10 toes of head) submersible propeller pumps (intermittent duty) for the emptying of fish tanks.
The Innhavet RAS plant has thirty-four fish tanks of different capacities (92,000 to 264,000 gallons) in 5 separate major sections. Each part is unbiased from the others and includes its own complete water remedy system in a semi-closed loop (98 percent recirculation plus 2 percent make-up water). The brackish water from the fish tanks first flows by gravity to a rotating drum filter for the removing of the main suspended strong particles. It then falls into an MBBR (moving bed biofilm reactor) for TAN (total ammonium nitrogen) discount. After passing through a countercurrent degasser for the stripping of nitrogen and carbon dioxide, the handled water is lastly pumped to some head tanks, previous to oxygenation and return to the fish tanks.
In each fish tank, the water is absolutely renewed every half an hour. The well-being of the smolts is very depending on a continuing flow of water via the ability. The reliability of the recirculation pumps is, subsequently, of paramount significance.
High general energy performance of the RAS plant means a greater environmental footprint and decreased operating costs. Consequently, the main components of the water treatment loops will have to have top-class efficiencies, significantly the recirculation pumps.
As a long-term provider of kit (pumps and turbines) to other Nordlaks crops, Sulzer was concerned at an early stage of the new venture. In collaboration with the Momek Group, a big industrial service supplier in Scandinavia, the pumps had been carefully selected, not only to fulfil the necessities through the guarantee interval, however to run optimally and economically throughout the whole lifetime of the positioning. For the recirculation of the brackish water, fifty AHLSTAR and BE process pumps in duplex materials have now been installed and are working constantly. In addition, 5 VUPX submersible propeller pumps are used on intermittent responsibility when the fish tanks are emptied through the transfer of smolts.

By selecting to work with a trusted companion, the consumer made certain to get fast and permanent technical help, in addition to the best products. The recirculation pumps have the next major benefits:
Extremely high hydraulic efficiencies that by far exceed the strictest vitality laws for water pumps. This means huge vitality savings over time and smaller total value of possession, responsibility factors close to BEP (best efficiency points), low rotation speeds, and inflexible baseplates grouted in concrete. The pump items are working smoothly with minimized vibration levels. Superior-grade materials is used for all wetted components. For the choice of pump materials in touch with brackish water, the long-term perspective favored duplex stainless steel rather than 316SS. Duplex steels have better design power than austenitic stainless steels, as nicely as higher corrosion, abrasion, and pitting resistance. In เกจวัดแรง , maintenance costs and the chance of downtime are lowered.
Sulzer is a recognized supplier within the fish farm market, with revolutionary and proven pumping, mixing, and aeration options, and provides extremely energy-efficient merchandise with low life-cycle costs and the smallest potential environmental footprint. As a cloth specialist in a variety of fresh water, brackish water, seawater, and brine applications, we can provide pumps in cast iron, 316 stainless-steel, duplex, super duplex, SMO, etc. .
