High pressure centrifugal pumps
Our range of our high pressure centrifugal pumps includes models with a wide range of performance characteristics. At maximum pressures of 25 to 100 bar, the reliable OSNA high pressure centrifugal pumps pump volumes of up to 600 m³/h upwards. OSNA high pressure centrifugal pumps can be found in water supply systems in residential and building construction, in vehicle washing systems, in fire extinguishing and irrigation systems, in mechanical engineering and various industrial applications as well as in mining, where they can overcome pumping heights of up to 1,000 meters. In addition to seawater, process water, service water and brackish water, OSNA high pressure centrifugal pumps also transport alkaline and acidic liquids, condensate, fuel, drilling emulsions, as well as coolants and cutting fluids. The space-saving vertical design of various OSNA high pressure centrifugal pumps is particularly aimed at system planners.
