Replacement speed 'switch" for a mcp 655b

post #1 of 6
Thread Starter 
So I was wondering if anyone might know where I can get the actual red vario switch or whatever it's called for the mcp 655. My pump got stuck on speed 1 and I took it apart and noticed that red turning "switch" that adjusts the speed broke in half.
I contacted swiftech, but they don't have spare parts and couldn't tell me where spare parts might be available from . I know swiftech just rebrands these so maybe I can reach out to the manufacturer, but I don't know who that is.

Anyways any help on where I might be able to get this part from would be appreciated!

I believe the pumps are made by a company called "Laing'

Is the red dial broken from the white base and spinning freely or is the base broken?
If the red dial is just spinning freely you can just take it out and use a small screw driver to adjust speed instead.
If the base is broken that is the potentiometer that controls speed.

I doubt you will find a replacement pot but what you can do is is pull the pot completely off the circuit board. In this state the pump will run by default at about 70% power. If you solder wires onto the the 3 contact points left by the pot you can loosly control the pump speed by joining the wires together in different combinations. Joining one pair will stop the pump, another will give minimum speed, and the final will give full power.

If you could find a potentiometer with the same specs you could solder it onto the wires and mount it somewhere for external control.

The voltage controller will still only supply 12v and the pump will still run at the speed it is set to. You could vary it from stop up to the speed the dial is set. If its stuck on 1 it won't go any faster.

Thanks a lot Jack.

It is the red knob. Guess those aren't available, but it's good to know I can use a screwdriver to adjust it still.

Thanks
