chiller on Return Pump, or seperate?

[wiszmaster]

I have a 1/2 HP chiller (barrel) that i need to hook-up.

Question:
Run it inline, on the regular return pump, or do i need to get a seperate pump from the intake of the sump & dump it back into the sump right before the end of the sump, where the return pump takes te water back to the tank?

tank:
150g

sump:
100g

chiller:
1/2 HP

return pump:
Little Giant 4-MDQX-SC (~1950GPH @ 6ft)


i doubt i'm putting that much flow through the pump though ... i have it going from 1" outlet right down to 3/4" for the return of my tank.

would this flow be OK, or is it too much to be effective for the chiller?



Thank You,

marco

I think you would be fine. I have 2400gph going through my 3/4hp. I would run it off your return. Check the specs if you can and see what the recomended gph is. It should be within that range.

thats just it ... i don't know what the specs are. i bought it used, and it doesn't list a model, or specs on it.

Thank you though.

NOT me. I like separate line and feeds whenever possible. What if the sump pump goes out? NOT only do you NOT have circulation and mechanical filtration, you have do NOT have cooling for the display â€"œ which adds stress to the inhabitants while you are replacing the pump.

I believe in redundant systems. In computers, that means as many as 5 copies of the same thing. While that is certainly impractical in aquariums, boating and airplanes, two copies of the same component reduces the catastrophe of failure tremendously. I like multiple pumps, power heads, surge protection strips and batteries, even on small home PC and aquarium systems.

This is good advise. I did have a situation when my pump went down. But I have a backup now so all I have to do is switch it out.

If you dont have a $$$ problem or a real estate problem, I would add a pump; from and back to the sump.
I too believe in redundancy and extras. I'm using 3 Darts and 3 PCX55HP on my 390, so I can prioritize if I have problems.

IMO running the chiller through a closed loop would be a much better idea, than running through the main return
