Joshua, Pumps typically set the flow rate for a loop based on their rated flow rate and the value of the input control signal. There are some pump models that will allow you to set the control signal to a value greater than 1 and therefore to exceed the pump's rated flow rate. I would recommend that you break your flow loop by removing one of the connections (the one that returns to the pump would be best). Then use an online plotter to look at the temperature and flow rate coming out of each component in the loop. Verify that you do not have any incorrect connections. Once you are convinced that there are no connection problems, reconnect the loop but disconnect whatever is connected to your pump's control signal. Force the control signal to be a known value either by setting a constant input value or by setting an equation. I think these tests will probably lead you to the problem.
