pump flow rate

[mmramos]

Anyone knows how the flow rate control for those submersible pump works? When I lower the flow rate does it also lower the power consumption? Motor spinning slower?

Thanks.

No, it just blocks the waterflow.

Hi Bryan,

It blocks the water flow on the output? I think that will stress the motor right?

You can use rain bar to lower the flow rate

Not sure about the stressing the motor part, I guess the back pressure might affect somewhat. If you find the pump flow too big you can split the return into 2 or more outlets or as suggested, a rain bar.This is good for spreading circulation, I find rainbars a bit restrictive as well and usually drill extra holes.

Hi Sheng,

So that means that lowering the output using the control bar on the pump will stress the motor? I should always put it at max and control the flow rate at the end using a rainbar?

Thanks guys.. yup, that's what i did - drilled more holes on the rain bar and set max output at the pump
