Jebao Cross Flow Pump

I'm confused. You say the most efficient manufacturer will get the job, that the company that copies another's new product will win, that if a consumer does not like the price of a product, s/he can chose not to buy it, and that's how capitalism works. So I guess you're saying that Jabao is following the principles of capitalism?

Sorry if this is useless but have you pulled it all apart, rinsed and scrubbed(vinegar to maybe), and put back together? Or is it purely a controller thing?

Never useless from you Jason.
I took it apart and both sides spin free and easy. The motor spins free when I turn it by hand. This motor doesn't run on either controller (I have 2 Crossflows and a 3rd on order now) and the other Crossflow runs fine on either controller. I assume this motor is just dead? It's not frozen, it just won't run and gives the red light. But the bad motor is in a vinegar bath now! :thumbsup:
To others who have had motor failures: Have the motor failures been frozen or did the motor still turn easily by hand?

You say you have other cross flows have you tried using other controllers and power supplies to make sure that it's not the power supply or controller and isolate it as the pump that's the problem

could be a bad motor. try hooking it up to the controller with the cage and propeller removed and see if it spins up when you plug in power to the controller. It's ok to let it spin dry for a short period of time if it does spin. If it really does not spin or move, then you now have spare propeller and cage.

Yes and yes. I kind of thought that was clear from my post. The dead drive does not run in the other system (controller/power supply) and the good motor runs fine with the dead drives controller and power supply. I've tried running it without the cages. Nothing. But the shaft spins freely by hand and the cages do as well.
I guess I'll just have spare cages, controller, power supply and magnetic base if I ever need them once the new CP-40 arrives. Anybody need spare parts?:wavehand:

10/4 don't know how I missed that I was just asking I had a problem with one cp40 getting the red light within a week I was waiting for aquatic deal to come up with a solution for a month in the meantime I ordered a second pump from a different vendor due to my experience with aquatic deal and a pair of aqualink T1's anticipating the repair of the one pump so at least I have it on hand when I get it.
after going back and forth with the one vendor I just got frustrated and hooked the pump up to the T1 and both work I think I had a fault in the controller or maybe the controller's too sensitive but both are running fine aquatic deal agreed to send me a replacement or refund me my money upon shipping it back to them at my expense after they receive it but after a month-and-a-half of going back and forth and waiting for them to contact me I just gave up and since it's running with the aqua link T1 I see no need.
I didn't want to wait no longer as it took him a month to ship it to me and then I waited a month and a half for them to figure out a solution on the dead pump with just emails exchanged back and forth I figured if it's running with the T1 I just leave it and if it dies I'll replace it with a different pump easy peasy less hassle

On mine with the exact same symptoms the impeller/cylindrical magnet spins freely in the motor block..
I suspect that the ceramic bearings are out of round/oversized hole causing the motor to not stay centered and not be controlled properly..
If I move/hold it perfectly I can get it to spin just a bit.. But then it goes off center due to the bushings and just stops..

These newer BLDC type motor pumps do not have any electronics in the pump. It literally has the 3 wires going in and forms magnetic coils that pushes against the stator magnets. if the coils are powered and magnets are energized, it is supposed to repel the stator magnet and start the motion. So if it does not spin, then the coil is not getting power. The controller can detect if the motor is spinning and after a few seconds of start up time, it does not detect spin, then it will flash the red light.
The other thing that can cause a red light flash is over current. Typically when I plug in the power jack to the controller, there will be some sparks. This is the initial current surge to charge the big capacitor as well as the current surge to start up the motor.
Ron, do you get the sparks when you plug in the power jack to the controller that is connected to the pump?

if you have a multitester, you can measure the resistance across each of the 3 terminals on the connector to the pump. The resistance should be a few ohms and should be about the same for all 3. Mine measures about 6 ohms. Any one that is open or shorted will cause the pump to not turn.

Well, I just read what you asked about and offered in the way of help d0ughb0y, so I'll check into those points. Yes I do get a spark if I plug the controller into the power supply. But I've always put the entire system together first and then plugged it into the wall.
And today my 2nd CP40 failed. I think I'm done with anything that is first generation Jebao from now on.

Hi everyone,
so my cp40 is not working anymore. I bought it whrn it first came out on FS and a few months later - red light on the controller. FS sent me a new replacement motor part (v3) and it worked fine for a month. Now the issue is that on W1 (which is the mode I use) 1 of 2 things happen: the controller decreases speed to speed 2 or the pump gets like stuck emitting vibrations. I contacted FS and they told me that the v3 motor part can't work with the "old" controller on w1 mode due to "overheating" / protect mode. I'm really upset about this pump and althouth I do love the water motion it gives, I've never had so many issues with a pump before. (And the pump it's just five month old!!)
Has this happened to any of you? Have you heard of this "protect mode"?
Thanks!
PG

For a little while until it dies :spin3:

Well the replacement Crossflow I ordered was in the tank for all of a week. I ran it at less than half speed and in one direction only and it has died already.
I've never been a Jebao basher. I run Jebao wavemakers and Jebao return pumps. But I think I'll wait for gen 2 or gen 3 before I consider another one. BTW, the less sturdy feeling Maxspect I bought used and have had running for a couple of months before I got the Crossflows is still running like a champ. This may well be a case where spending more than twice as much for the other brand, is in fact, a good idea!
