There is negligible pressure drop in a hydraulic separator and therefor no reduction in flow to the primary (or the secondary). The counter-flow is important for proper mixing when the flow rate in the primary and secondary are not equal (most of the time). Take a look at the explanations in our idronics journal issue #15.
