I have a couple Jebao WP-40's and they work at 24v with 5v PWM signal. I have connected them to the LED channels and they work good, just need to put in a system to use them. I just tied in the signal wire and a common GND and ran it off the original power supply. One thing with mine is if the PWM signal was maybe below 2v the pump wouldn't run good so the code needs to jump from that point to off. That's why it's not good to run them on the LED channels right now. I'm guessing the other pumps are similar, the controller for the Jecod looks close to the WP series.
For the DC ports the signal is just a ground, no data flows through it. I think if the power supply is located at the pump a long GND would be ok. Data going through a wire is a mystery, using Serial it can travel over 100ft no problem, using I2C 6ft is pushing it without buffers, doesn't make sense. :)
