DICKOW® hot water circulation pumps, type NHL, HPL, HPR and NHM, have been developed for medium and large size heating plants, for heating calendars, presses, large buildings and similar applications which require temperatures > 140 ºC (284 ºF).
The design of the pumps is based on long years of experience in the field of handling hot water and grants high availability and reliability in operation.
The NHL series is designed for pressures up to 45 bar @ 238 ºC (464 ºF), maximum capacity is approximate 900 m³/h (3960 gpm) and differential head approximate 150 mLC (492 ft).
The HPL/HPR series is designed for pressures up to 80 bar @ 280 ºC (536 ºF), maximum capacity is approximate 300 m³/h (1320 gpm) and differential head approximate 60 mLC (197 ft).
