May I ask, for an indirect system of electric heat constant-pressure boilers, what is an appropriate head value for the primary pump?
Thread Content
The boiler is an electrically heated atmospheric pressure boiler, and the heat exchanger is a semi-volume type heat exchanger. Does anyone know the approximate range of choices for Yang Cheng?
Does anyone know? Design experience for direct gas supply in atmospheric-pressure boiler rooms is also useful.
I think the problem description is incomplete. . . To calculate the pump’s head, resistance calculation is definitely necessary, but there’s no information available regarding the approximate dimensions of the equipment. . How to do it
Hello, you can use the online selection tool on this link to choose a pump – just fill in the parameters as required, and remember to leave some margin.
