Head loss on Eheim Compact series?

[Myka]

Anyone know where I can find a flow chart for the Eheim Compact series pumps? I'm looking particularly at the 600 and the 1000, and wondering head loss as a return pump for my nano. I've been Googling for 20 minutes and can't find a darn chart! :eek:

I can't tell you what the official head loss is, but I can tell you that these pumps move a lot of water. I have the larger one pushing 4 large reactors in parallel and I still need to release pressure through a 5th parallel outlet.

Headl loss will help you select the right sized pump. I can only speak to the quality and ability to move a lot of water. I really like the pumps.

idk about charts but i run the compact 1000 (rated for 240 gph) for a return on my 33 gal, it also feeds my 27 gal hex.

Thanks for the replies!

I want it as a return pump for a 20 gallon tank. The 600 (160 gph) says max head is 4.3 feet, and I will have 3'7". I'm just wondering if I'm going to get a lot of head loss being fairly close to the max. I would prefer to have 120-150 gph through the sump, and definitely don't want anything less than 100 gph.

Maybe I will email Eheim.

ever tried look up EDEN as pump manufacture instead?? EDEN makes those Eheim compact series pumps.

Ya I tried that too...

3', 7" including friction losses or just static head?

Those charts aren't necessary that accurate anyway and you'll find similar pumps will have the same pattern so just go by something similar.

[Myka]

That's not including friction loss.

Although today I notice the nano is leaking, so maybe I will be having to get a bigger pump for my other (larger) nano anyway... Rrrrg!

this is the chart for the Eden version of the pump. and seems like Eheim only offer 3 versions 2000L, 3000L and 5000L.

the box seems to be bang on for head loss... i use a 200 for a waterfall in a tererium and its useless at 2 feet... i use a oddysea 700 for my 20 gallon... works good at 4 feet. i figure around 250gph. cheep pump works great.. i have also seen these pumps used on skimmers and work awsome.. very fine bubbles and the pinwhell comes with the pump.
