Eheim 1250 or 1048?

Nomad2000 · 07-10-2002, 04:42 PM

I have enough room for Eheim 1040 or 1250 and I have both pumps. My intended setup -Lian-Li68, Athlon XP 2100 (no OC), Innovatec WB, GPU (not for demon video-speed), NB, BIX with two shrouds and two 120 Papst fans, GPU, NB, a stainless steel reservoir about 1/2 litre. What I need - no EMI, no noise. What pump is better - 1040 or 1250? What fitting is better - 3/8 or 1/2?
Thank everybody.

No OC, then the 1048.

3/8 would fit it very well.

would the 1250 be better when you have .5" tubing?
would the flow rate hinder the radiator from doing its job?

The soultion is simple, set up the system with 1/2'' fittings, then try both pumps, use the one that gives you lower temps,then tell us the results

Assuming the 1040 is a 1048 pump, here's the raw data on them.

Pump-------------Pumping Rate------------------Pressure---------Power-------Inlet------------------Outlet--------------------Deminsions
Eheim 1048----158 Gal/hr (600L/hr)-----4' 11" (1.5M)--------10 W---------1/2" (13mm)---------1/2" (13mm)---------5.8" x 3" x 4.7" (147 x 75 x 118)
Eheim 1250-----317 Gal/hr (1200L/hr)----6' 7" (2M)----------28 W---------3/4" (17mm)----------1/2" (13mm)--------7.1" x 3.8" x 4.7" (180 x 95 x 120)

They're not supposed to make much heat, but the shear size difference in the 1250 vs the 1048 may effect your placement of the items in your case. The 1048 is good for 1/2" in and out. The pressure is a lot more in the 1250, though if you're necking down to 3/8" (which the Innovatek's are) I'm not sure how well that'll do. If it was me, I'd go with the 1048 (smaller, quieter) and 1/2" fittings and tubing all around.

I'd love to hear the results on either setup though!
