Controllable feed pump to use with Neptune?

[Gordonious]

I'm looking for a controllable pump that could be used with a Neptune Apex controller which I can have run normally at around 100gph and ramp up to 950gph or more. What I'm looking for is a feed pump or return pump, not as power head or circulation pump for the display. Does Tunze make such a pump?

Closest they make is a 1073.050, which will do from 290 to about 790gph on the 24v jumper at 0 feet of head.

Errr. I don't think that would be enough and not sure how to make it slower, but then allow it to be greater.

I also thought the Apex pushed things 0-10V. No experience with this just fuzzy memory.

The 0-10v on the controller is not the power that supplies the pump it is just voltage used for a controlling signal

 

[Gordonious]

Understand, but how does the Neptune controller control this pump?

 

[shawnz28]

Not sure I understand the question. It controls it just the same as the Tunze would by regulating the control voltage thru the plug into the junction box for the pump based on the percentages inputted to the Apex. The pump is still getting its power source from the supplied power supply which also plugs into this box. Does that help?
