The DICKOW-Standard pumps, series NKLs according to EN 733, are designed as centrifugal pumps of light duty for handling heat transfer media.
Dimensions and performance range comply with the requirements of EN 733. Thus, the performance range is subdivided such that best efficiency is granted at all service conditions.
The NKLs pumps will be applied as circula ting pumps in industrial heating plants. The performance range covers capacities up to 400 nf/h and differential heads up to 90 mLC in 50 cycles service.
The maximum allowable operating temperature PT is 340°C without additional cooling. The NKLs-pumps with the single acting N10q- seals can be applied when handling HTM with boiling pressure at operating temperature below the atmospheric pressure (<1 bar abs).
