People just get so confused with terminology of the stuff .. You have an internal movement of water thats Circulation or movement of water is actually called Volume and then you have a true flow rate thats is what moves along a controlled path pipe trough flume anything that contains and transports a liquid ..
A internal circulation needs a high volume and low pressure pump like a swimming pool or a mixing vat for chemicals or foods and the pump from sump to push water or chemicals back to the holding storage tanks has to be a pressure pump. A 1 inch pipe can only handle about 700 GPH if pipe is a straight shot no turns and a liquid with the viscosity of freshwater.
When you have worked with pumps rated from 2 to 50 HP to push water from a chiller or boiler to a 10 or 20th floor convector or to supply water to the top floors of tall apartment's city pressure can't do it, you have to understand and no how water moves .. Its not a hobby when you have to figure the loads and heat loss and have to get a certain amount of a chilled or heated fluid to keep someone warm or cool . And the pump cost several thousands of dollars you do the math .
Again why over size the pump ? it will just wear it out or create excess heat and or expense to operate . Hell put a Mag 2400 on it let it rip (: I'm just offering you over 50 yrs or real world pump and flow experience not hobby toys .. _________ Some of the world's greatest feats were accomplished by people not smart enough to know they were impossible (Doug Larson) |
