6100 ?

[Zoom]

Is a possibility that out of my two 6100 one is pushing more water than the other? I switch the transformer but is not it. one pump is definitely stronger than the other, any suggestions?

Check the driver connection. Due to the electonics and slight variance in resistance a difference of up to 10% is possible. Make sure they are clean and the driver is at full power and due a test without the multicontroller. Since the components can vary by as much as 10% the resulting power could vary by just as much but one could be 10% more powerful than normal just as easily as one could be 10% less powerful than normal.
