Pump selection
Thread Content
Supply and return water temperatures of the primary heating network； 100/60 ； Secondary network 60/50. Heat load: 889 KW. The building is 36 meters tall. What are the flow rates and head values of the circulation pump and the make-up water pump? How was it chosen?
The head of the circulation pump is related to the heating radius; just apply a formula: (Heating radius × 0.8 / 200 + 17) × 1.2. The head of the make-up water pump is related to the height of the building; the head of the make-up water pump = building height + resistance losses due to equipment. I hope this helps you
Thank you for your help, but I still have many questions. I don’t know how to ask you for advice
