Tunze 1073.05 Head loss question.

[2Quills]

Would this pump give me 600gph at 5ft of head height running at max output? I can't seem to find any info for this.

Thanks

No, flow at 5ft of head would be about 450-500gph.

No, flow at 5ft of head would be about 450-500gph.

Ok, thank you. I had checked out the link to the user manual but the graphs were to blurry to read very well. I don't suppose you know if a slightly larger pump is in the works any time soon do you? The 1073.05 sounds pretty sweet but it's a little bit too small for me. And the 1073.09 is way over kill. Would love to see a pump from Tunze made for tanks in the 120g-180g range.

In the fall 1073.090 will be replaced, I don't have any info on the replacement but suspect it will be more versatile.

I'm also very interested in the 1073.05 as sump return and for chiller.
my tank specs:
- head loss height;50'
- overflow up to 400gph
- chiller needs 240-960gph

would this pump work or do I need a stronger pump?

Iam also very interested as a return pump and for my chiller.
Tank specs:
- head loss height; 50"
- overflow: up to 400 gph
- chiller: 240-960 gph

will this pump work OK in this situation?
Love the adjustable flow rate , reported reliability and silence on this pump, but am concerned it won't be powerful enough.

 

[rvitko]

At 50" it should do about 520gph at full power, my concern would be the following-

Does that 50" include the head pressure within the chiller (usually 2ft) due to elbows, etc.

 

[herbklee]

No. 50" does not include head pressure from chiller or plumbing.
Is there a strong variable recirc pump from Tunze that would be more appropriate?

 

[rvitko]

That is the biggest/only return pump that is electronically variable. I think the 1073.050 would work, but including the resistance inside the chiller you would likely be closer to 350gph at full power.

 

[herbklee]

Well since my overflow is limited to 400gph, I suppose the 350 gph total head inthe DT should be OK?

 

[rvitko]

I would think so.

 

[herbklee]

Thanks Roger,
I guess I'm ready to pull the trigger.

Would this pump be in the ballpark for my 135 SPS tank?

 

[rvitko]

To me it would be, but everyones needs and opinions vary, it will do about 550gph at 4ft of head. I generally target 3-5 time turnover through a sump.
