Fig.1 The new NKX heat transfer oil circulation pump

The pump manufacturer Dickow has developed a new pump line NKX for circulation of thermal oil. The pump casing is designed for 16 bar and 350 °C. The new pump line extends the application limit of the previous NKLs-type. The new NKX will replace the series NKLs with exactly the same dimensions in future.

The NKX is used as a circulation pump for hot oils in industrial heating plants/units. The performance range covers capacities up to 400 m3/h and differential heads up to 90 m in 50 Hz services; and capacities up to 2,500 US-gpm and differential heads up to 400 ft in 60 Hz services. The dimensions and performance range of these centrifugal pumps are according to DIN EN 733, that means range is subdivided into different pump sizes in order to achieve best efficiency for all service conditions inside the envelope.
