Problems with noise. (Pump, Res)

post #1 of 7
Thread Starter 
Hello.

I have posted pictures of both the items in my loop, that I believe are causing problems with noise in my system.

EK-DCP 4.0 12V DC Pump

EK-Multioption RES X2 - 250 Advanced

The pump is obscenely loud, I think this is possible due to air being retained in the loop.

The noise from the res, is due to the water trinkerling down and making a splash, some may consider this comforting, but yeah, I find it annoying..

What are the possible route I can take to minimise this. I also believe my loop is not complete full, yet it won't take much more water. And well it's annoying trying to fill it with more water while the system is off/on.

I have my pump isolated with foam tape provided by EK. Yet it still vibrates like a beast.

You can buy pump dampening materials but a sponge will work just fine. The noise from the pump is probably caused by the pump vibrating against the chassis.

Find a sponge somewhere in the house and put it underneath the pump. If it solves the problem, find something to stick it to it (or paint it black first to look a little better).

Remember that most noises are caused by vibrations and thus need dampening using rubber or sponge or some other material.

As for the noise of the water trickling down the reservoir, surely you could stop the 'splash' noise by filling the reservoir up some more, eliminating the splashing as the water falls down?

Yeah, fill up that res. If using a top inlet, the water level needs to be higher than the bottom of the tube.

Also as suggested, don't mount the pump to the case, it should float freely on some soft foam like material and should have some tubing lenghts between any fixed objects and the pump so vibrations are no transfered along tubing.

Depends on the acoustics of your case, acoustic impedance of the materials in the case, a whole bunch of things.

Excuse my ignorance or mis-reading. But how do you propose I fill the res, with water already in the res, while having the filling tube lower then the lowest tube?

I have tried filling the res with more water. But the problem is.

1. Filling the loop with water while the system is off is theoritically impossible, because the res is already full.

2. While the system is on. I use a tube connect to the top most port of the res, and begin filling with a spare compression fitting and long tube and funnel. I fill the funnel like 2/3 up, and it doesn't accept more water.

Do I need to slightly open one more port to act as a pressure release so water can just flow in from the funnel? or does it need to be like a vaccum so it can suck more water in? Or I'm just being retarded?

Thanks.

Well, slightly loosening a cap could help, however if the reservoir won't accept any more water I'm afraid there's little you can do. It's simply how the reservoir is designed.
