I suspect you two are not comparing the same Jabeo pumps?

Chappo there is no 5000 in the JPP series. I know the one you're referring to (5000 on ebay), it has a different shape (more box like) than the JPP's. I don't know the difference, but I don't think it should be compared to the JPP's until someone actually has one to compare... I suspect it is a cheaper - perhaps not the same quality/type (JPP are vortex) pump?

Now if I had an edit button...

The 5000 draws more power than the JPP's and I don't think it can be plumbed as an inline pump...

In pumps how do you work out running costs say 100 watt

The resun pumps we are selling do the soft solids fine so long as you remove the filter sponge and if you leave the cage on, it prevents unwanted fingerling entries. As for comapring to the Jebao, I dunno, but we are using the ones we sell with no problems at all.

mylesau , Thnaks for pointing that out ,, agreed no use comparing oranges to apples.

monya ,, I've had a resun biofilter/power head for at least 10 years now ,, in all that time it clogged once ,, I just scraped the algie away with a stcik ,, and had nil problems.

As for power less power consumption,,, well , say a good pump of $250 uses 10 watts less than a $100 pump ,, takes a LOT of time to use $150 worth of power.
What I do like about the Jabao is that even the guy on ebay guarrantees them ,, he even pays the postage for repairs if they die.

As with most things , it's an individual choice ,, some love Mercedes, some love VW beetles , other's want only a push-bike. They all work.

100w pump running continuously will use 1kwh per ten hours of running. 1kwh = around 15c depending on where you live.

AFAIK

F&F,

also be careful with Watt ratings, many pumps driven by induction motors state mechanical power NOT electrical.

times the voltage (240) by the amps, it will give you the watt rating to within about +/- 5%.

magnetic pumps like the cheap aquarium ones usually state electrical power.

you may be very surprised that a cheap single phase electrical motor (most of them ) will double up as a heater loosing upto 40% of its power consumption as heat.

Good for this time of year

yep. lol. i think AM has some serious heating issues one summer (its always summer up there!) due to pump heating.

Does anyone have any experience with commercial aquaculture type pumps- something that does 1,000-10,000 GPM or would that only be irrigation pumps that can handle that kind of volume?

On a side note, there is a new irrigation pump being tested here- it uses ammonia for fuel, rather than diesel. The purpose is to eliminate emissions since it burns cleaner. Since diesel has hit over $5.00 and ammonia is only $2.00 per gallon, there is a significant advantage there as well.

Angie ,, I use some largish pumps on my farm in Thailand. From memory the submercibles are good for around 2,000 litres per minute ( thats about 450 gallons a minute).
If you want efficiency and economic running , you want to get whats called 3 phase motors ,, you need 3 phase power connected to run them.

I'm wired for 220 so three-phase is no problem. How energy efficient are they?

Substantially more efficient than your normal 120 V ones and petrol or diesel pumps are a joke when you calculkate how much they cost to run.
The other GREAT thing about 3 phase pumps is you can learn how to rebuil one ( new bearings etc) in about an hours and once you know how , you can do the whole job in 30 minutes .
It's important you match any pump to the need of the job ,, head resistance and required flow at that head.
Also use the biggest pipes you can ,, less resistance to water flow.

I already know about pipe resistance, I plan to use larger pipe and sweeps as much as possilbe and eliminate any elbow fittings.

Your "on the ball" ,, fantastic.

Pull as much info as you can from here ,, but if your using earthgen ponds don't forget you'll need to get rid of any sand etc before putting the water into the gravel beds.
