Testing water pumps?

[Chomie]

Hey I just recieved my Swiftech MCP655 Pumps today and would like to test them to make sure they run, if I were to plug them into my PSU and turn it on and off quickly would it hurt the motor? I'm assuming yes but some input would help... I don't have any of my other parts yet thats why i'm asking.

Yes you will damage the pump. They aren't designed to be run dry and should only be run with a positive supply of water. (The 655's especially make an awful grinding noise when they run dry...... ;) )

Yes it will damage it. You can always fill up a large bowl or tub of water to test it out, just make sure that intake stays submerged or you have a hose going into the water or something.

as pictured turn image counter-clockwise, this will have the inlet facing the ceiling

keep that position and plug the outlet that facing left wall

fill the inlet till pump cavitiy is full

now you can power the pump with keeping the pump outlet plugged and inlet full of water

if run the pump dry will cause rotor vibrate when get your loop finished

oh just run pump only VIA of jumping PSU the Green to black

Sounds like a plan, ps the box shows the inlet is the horizontal barb fitting and outlet is the vertical fitting!

would wait till you get your loop done and then fill using the jumper method KC posted till your loop is filled and tested.

Yes sounds ideal but being from Alberta, Canada I have to wait for Canadian shipping... so if I do have an RMA it'd be better to do it while I'm in the building phase versus almost being finished.

Thanks for the advice!

Go to the local hardware store, buy $3 worth of clear plastic tubing, then make a small loop from inlet to outlet, that way you see water pumping, don't kill it, and you will need the tubing eventually anyways.

If that's the case, get a shallow bucket of water and and drop everything into the bucket below the nut, so intake and outlet are submerged obviously the motor is not and power your pump... even could just submerge the intake and point outlet back into the bucket....

not a good thing to do for the cermic ball isn't touching water with your method
