Jebao pump for mixing station

I find that jebao pumps are not ideal when used as an external pump. The way the volute is sealed to the motor housing via an o-ring, doesn't lend itself the best water tight seal. Plus the volute is fairly thin plastic which doesn't help.
You'll have to be mindful of that.

You use the slip fittings that should come with the pump, unless you got the version which does not have it.
If thats the case, you probably need to go on amazon, contact CNZ Lighting, as i think they are a main distributor for jebao, and ask if you can buy the slip fittings for your pump seperately.
But it would look like this:
Then just use pvc cement, and glue to the slip fittings.
The o-ring would go on the inlet, and then a compression ring would compress the oring on the inlet and slip fitting forming a tight seal.
Remember do not forget the oring, this is the #1 reason why people complain it leaks, but its like a Union, just need a good amount of tightness on the compression ring, and make sure your pvc cement is cured and applied properly.

actually some of them are bolted/screwed compressing that oring.
I am thinking your talking about the impeller chamber and volute and the housing that usually twists on and off to get access to the impeller?
The bigger ones, and ones i think they thought would be run externally are fastened with a Stainless fastner.
you can see the fastners on this guy.

Perfect, that was my concern, the slip fitting not being able to be glued to the pvc. Wasn't sure of the material used in the slip.You use the slip fittings that should come with the pump, unless you got the version which does not have it.

I think it's mostly about the type of plastic chosen for the volute. It's on the thin and brittle side, which doesn't lend itself to keeping a seal long term.actually some of them are bolted/screwed compressing that oring.

Admittedly, I used jebao pumps with metal fasteners for my mixing station, and every single one of them begin to leak after a few years. And it's always the seal between the volute and motor.
Mostly that the volute got brittle and couldn't maintain the seal. There was more than one that the tab for the screw cracked.
In my book they don't get a high rating as an external pump.
