I have 2 of the speedwave brand (most of the pumps are identical) operating as a closed loop outside of the water for about a year. No leaks. Fairly quiet. I do have them wired into an arduino controller ramping them up and down.
I have gone through a few powersupplies (replaced under warranty). Keep them cool and they are fine. |

Thanks a lot guys !!! This is Great input here
DC pumps are still in their infancy, but they do prove to be more efficient and quiet. Being able to control the speed / flow is a big plus for those that want wave maker. Quote:

I have the pump signal wire connected directly to the arduino output and the negative tied into the supply output negative.
I do also have a resistor and cap on the signal line to change the PWM to analog. The speedwave pump doesnt really need the resistor/cap but my jebao wp pump does. |

I run a Speedwave 2640 as my return pump. Been using it for almost a year now. But I'm not using the stock power supply. I'm using a 19V laptop PS with it.
