Controlling the speed of a D5- non vario

post #1 of 9
Thread Starter 
So I made a noob mistake and got the non vario D5, so there it no speed adjustment nob on the back. I also don't have an extra external bays for a fan controller. Is there any way I can limit the speed of my pump to reduce noise? Thanks!

The variable D5 motors just have a little adjustable voltage regulator on the body. If you have regular D5 pumps, you need a pump controller which will limit the voltage to the pump to speed it up and slow it down.

The first one will probably melt. The second one looks OK as it can handle 3A.

That's what I figured lol
Any others people would recommend?

There is a limit to how low you can have the voltage before the pump won't start or won't run. Its quite high like 10 Volts

The speed dial on the back of a D5 vario does not reduce voltage to the pump like a simple pot. It is a more complicated motor speed control circuit.

I'm running into a pump noise situation on a new EK DCP 4.0 pump. Did a quick test by hooking it up to the fan controller and the noise at 10V was definitely manageable. A huge difference in noise between 12V and 10V (w/ 8V being near silent).
Had to order a pump controller to control the noise. Wondering if I should have just gone with a D5 vario pump in the first place. Might have been cheaper in the long run...

if you haven't used it yet, have you tried to see if wherever you bought it from will let you exchange it for a vario model and only have to pay the difference? Even if they hit you with a restocking fee or some such it sure seems like you would come out better off than any of the other proposed solutions.

If they won't you might try to put the non-vario pump up for sale on the boards here and see how much you can recoup from it to put towards a vario model. You still might come out better doing that than having to spend ~$40 or more for some sort of potentiometer / controller.
