Backyard Aquaponics
A place to discuss aquaponics

I am looking for a couple pumps. I am estimating 100 gph, but will decide exactly how big once I see the prices. Does anyone know of a website to get some for relatively cheap, or at wholesale price?

Thanks

A 100gph pump would be a very low output pump.

ebay?

My aquarium shop had a little pump that was around $20. They claimed they were reliable, and pumped to around half a metre head. They were not trying to sell me one, and in fact have never sold me anything, they just give me stuff for free for some strange reason.

People are funny.

But I'd try an aquarium shop if the BYAP shop doesn't sell anything small enough for your needs. There are lots of little fish bowls that need little pumps.

Do you care about head height? Does it need to be submersible?

I don't know if this will suit your needs, but you could use the Maxijet 1200's (they're less than $20-25) and they do 200 gph. They also work as powerheads (but you have to pick what you want it to do). The MJ1200 does not have threaded adapters, so you would have to manually modify it for PVC. I use it as a pump to do water changes and it works very well. Many of the CPU Overclockers also use it for their cooling system.

Maxijet also sells the NJ400 which does 100 gph for about the same price but I've never used these, so I'm hesitant to recommend it, although it does exist and they're a pretty good company. The NJ400 has NPT adapters.

Also, eBay sellers have some that are around 100 gph but I've never used them to be able to recommend them. One seller I've seen sells Maxijet 1200 (knockoffs) for about $12-15 each (depends on quantity).

eBay is good for the smaller pumps. I actually found that Amazon and Harbor Freight (for US people) is better for larger pumps but occasionally you can find a decent deal on eBay for those too.

If either Maxijet will do, then Aquarium sites will have about the same price on them. Don't buy these on eBay, I've never found a MJ pump on eBay cheaper than on any of the big online pet supply retailers.

hope that helps...

thanks a lot. I think I will look into the maxi jet. That sounds about perfect for my price range

Anyone here that have tried a pump from a washing machine in a system?
I´m a newbee and decided to put up my first system from spare parts!

Jwhittak98 in this thread did..

People have talked about it and the general consensus was don't.

Apparently they have a bunch of electronic controls on them which you have to deal with.

Plus from looking at the impellers I don't think they are very efficient which means that any money you save on a pump you are likely to spend on electricity.

Thank you!
Didn´t seem to be sustainable in the long run, however I just came across a pump called AL-KO sub 8001 with a flow of 8000 L per hour (133 L per minute) is that one too powerful or is it ideal for an IBC 1000 L tank?
Pump price 30$
IBC tank 40$

AL-KO sub 8001
From what I can tell it's 350W, i'm sure there would be lower wattage pumps you could use.

Ok, never thought about that! What kind of pumps do you recommend? Pond pumps?
I think I read somewhere that minimum pump capacity should be 3000L per hour, correct?

I would go for a pump between 1500-3000 L/h... And don't be fooled by some of the really cheap high Warrage pumps, you will end up paying a lot more for power...

the 1350 one here should do for an always on system running a siphon or constant flood, or the 4000 for a timer run IBC running for 15mins per hour.

These pumps (or similar) tend to be what most people use, and they only cost the price of a half a dozen fish fillets a year to run.
