How can I test my new D5 pumps without tops installed?

[Euphoria]

I need some ideas and advice, please. I received my lovely new EK D5 pumps a couple weeks ago, my pump tops should have arrived about the same time but were delayed a week or two... or seven or ten. I've now been told it will be another few weeks or longer before they get new stock.

My concern is I only have 72hrs left of my return window, so I need to test the pumps to make sure they're fine and working without issue, if not at the moment I can just get them replaced but if I wait until my tops arrive and then find out there's an issue or dead pump I have to RMA. They were shipped internationally in really poor packaging which arrived pretty banged up hence really needing to test them while I still have the return policy.

So, if anyone knows of a surefire way to test a D5 pump without a pump top installed, without running it dry, and without getting water inside the motor I would be extremely grateful.

No.

 

And the pumps won't be dead.

"No"... what?

I know D5s are repurposed industrial pumps and are therefore *mostly bulletproof but the bright spark that shipped these put them in a large cardboard box together with nothing else, no foam, no scrunched paper, no packing peanuts, zero anything, and then shipped them over 3000km to me, so both pumps just bashed around against each other the whole time. When it arrived the box looked like it had been used as a football.

No you can't test them without a top.

And why did you buy them used??

If u just want to test to see if they turn on and work for a few seconds then u can, a short burst dry wont be harmfull. If ur so concerned then simply wet the impellar.

 

Running dry is damaging when done for extended periods of time, heat and friction causes the damage, however a short burst ,especialy if wet, wont cause any damage.

 

For example, Jay , over at JayzTwoCents, had to salvage a pump, he swaped out the impellars and ran it dry on camera for a second or so to ensure it worked and to show the camera, no harm done.

 

 

At 3:55. 

Again not recommended to run dry, but a few seconds wont hurt especialy if its neccesery for testing purposes like in ur case.

No, they are brand new, it just seems that the retailer has some morons working in their packing and shipping department.

That's very good to know, thank you. I'll give this a try.

Did you not buy them directly from EK?

No, very few retailers/companies ship to the country I recently emigrated to, or if they do the shipping costs are normally more than the item is worth, so I'm limited on where I can buy things.
