Kvaerner Hydro is the organisation comprising thosedivisions within Kvaerner Brug A/S of Norway, whichare concerned with Hydro Electric Power and WaterControl applications and its subsidiaries SorumsandVerksted A/S in Norway, NOHAB-KMW Turbin AB inSweden, Kvaerner Hydro Power Inc. in the U.S.A.and Boving & Co. Limited and Boving NewtonChambers Ltd., in the United Kingdom.

Kvaerner Brug is one of the main companies of theprivately owned Kvaerner Industrier A/S, which isamongst the largest industrial groups in Norway, withactivities ranging from oil and gas to fish processingand environmental protection as well as shipping andshipbuilding.

The operation of all the Kvaerner Hydro companiesis closely co-ordinated and the technology andexperience of each is available to all. Productsavailable include:

Gates All Hydro Power and WaterControl types.

Hydro turbines

Valves

Governors

Penstocks

Pelton, Francis, ReversiblePump, Kaplan, Propeller andBulb.

Spherical, Butterfly and FlowControl Valves.

All electro-hydraulic types

Surface mounted or covered,tunnel and pressure shaftlinings, bifurcations andtrifurcations.

Trash RackCleaning Equipment Various types and sizes.

Fishway Services Fish Passes and Fish Gates

Services, Repair,Refurbishment andUpgrading

TrainingAll services associated with hydro installations.

Since 1848, when our first turbine was delivered,Kvaerner Hydro companies have deliveredthousands of hydro turbines, totalling over 80,000MW in output. Continuous improvement anddevelopment enables us to offer hydro turbines of alltypes and associated mechanical equipment of themost modern design for the smallest as well as thelargest projects.

Hydraulic and mechanical research, developmentand design is carried out in our modern laboratoriesand by experienced engineers using the latestcomputer techniques.

Brochures giving descriptions of our laboratoryfacilities and all of our products are available onrequest.

VuuuTURBINES

Now designed for heads in excess of 600 metres thesingle stage pump turbine has superseded theoriginal idea of separate coupled pumps, turbinesand generators which is now rarely used.

Work on the first hydraulic and mechanical design ofa single stage pump turbine began in 1958 resultingin the two highly successful units at Cruachan. Sincethen we have designed, manufactured and installeda number of units at various sites, these include theunit at Juktan which was the largest machine of thistype in the world.

The brochure on our Hydraulic Turbine Laboratoryillustrates our excellent facilities for model testingpump turbines.

The mechanical design of single stage pumpturbines has proceeded in parallel to the hydraulicdevelopment and has seen such design changes asthe introduction of friction devices in the guideapparatus instead of the original breaking links andsimilarly the shaft seal of the radial carbon glandtype has been replaced by a highly effective axialseal. With our previous experience and ongoingdevelopment we are able to supply all sizes of thistype of turbine.

This reference list gives the main design data of allpump turbines ordered which have been designedand/or manufactured completely or partly byourselves.
