High performance return pumps that can handle head pressure with 0-10V

[aumoenoav]

Im looking for a proper 0-10V controllable return pump. I purchased two Jebao Pumps (DCP 18000), but those are not possible to be controlled by 0-10V anymore (as the old versions).

I know Red Dragon exists, but its quite a price, and I'm looking for a pump that can handle high head pressure (sump in cellar).

So any ideas here of pumps that can be fully controlled by 0-10V (via Profilux 4), that can lift at least 4 meters @ 25mm return tubes (as the flow meter is 25mm thats the thinnest part of my return) and using a manifold, so looking for a pump that can do at least 10000-15000 l/h @ 4-5 meters. (that gives a bit slack of manifold etc) that CAN be controlled by 0-10V

I think BDLC's (wavepoint?) are 0-10v.

Why opt for a controllable pump for return though? Flow is not usually changed once the tank is set up. Just a thought. If you aren't in a tropical setting where heat matters too much, I think I'd prefer a standard AC pump for durability.

Because when I use Profilux I can set it up to control the flow through the display with 5000 liters pr hour. If I change the manifold or anything in the sump the Profilux will automatically change the speed of the pump so everything keeps stable.

You have a flow monitor kit that the controller uses to adjust the return pump.
