Pump For water storage drum

[Benny]

Hey guys (Ryan especially )
Im setting up a water ageing drum under my house.... I have done the math, and its approximately 3M below the tank.. My sums tell me i there fore obviously need a pump with a head height greater them 3M....

What pumps do you guys reccomend? Was lookin at http://www.aquariumproducts.com.au/prod423.htm seems like it will do the trick...

Was looking at a sicce extrema but its head height is only 3m so i dont think it will work well, if at all

I dont need HUGE flow rates, ill only be changing 100L so 1000lph means 6 mins for the water change (i obviously will take the head height into consideration of the pumps flow)

Regards
Benny

Benny, (obviouslyi'm not ryan lol)

at what pipe size/diameter is the maximum head head/flow rate for the output you speak about for this pump...this can drastically change the results that you can get from a pump.

3m max seems like the maximum head pressure you'll get and so therefor it's the point that cavitation, at varying head pressures and heights can occur. I would suggest finding a pump that pushes out more water that desired overall but on average suits the flow rate you want at the height your pumping, hth

well the one in the link i provided has a 4m head height so it should be adequate... What are peoples opinions on the "sun sun" brand and "resun" branded stuff?

Hay Benny

sorry i missed this thread

pumps work on a "parabala" like ph does

as the head height goes up the flow drop significantly

ie:

0m head = 3000ltr per hour
1m head = 2500ltrs per hour
2m head = 1500ltrs per hour
3m head = 250ltrs per hour
4m head = cavitation

you are going to be doing big water changes, regulary

you will be wize to spend money on a Quality transfer pump at that sort of a height

unfortunatley that would be the minimum i would suggest

see the autofloat that will help you not destroy the pump without realizeing it

at the height you have mentioned you will still only get around 2000-3000ltrperhour

if you can save up, go for a davey sulage/soft suspended pump

it will cost even more, but once you get a few tank going, its the VERY BEST investment you can make. It will make the waterchanges a dream

haha i think my parents will kill me if i get any more tanks!!!

Dear god that wasnt the sort of adice i was hoping for lol..

I plan on gettin a 200L drum, and no more then 100L WC's at any one time....

Far out, so my best bet is to get something with a very good head height, as best as i can afford? I plan on fitting a float switch anyways in the drum, so it automatically fills it, and will also shut the pump off...

Im going about a fully automated system, with electronic valves or solenoids etc so it will drain it to a certain level, fill the tank back up, then fill the drum up again..

Just how i can automate adding the ageing drops, i dont quite know as yet.. will gladly take any advice,

Was also considering this pump http://www.aquariumproducts.com.au/prod825.htm

and a Resun King 4

LOL Sounds like a Wallace & Gromit device.

You can get a Sunsun pump that promises 5.5m head for around $120 or so. If it goes phut after a while, at least it didn't cost too much. Then again, you never know, it could last for years.

also sounds like a device that saves alot of time and hassle

And moreso im going overseas for 6 weeks in december/january and it means i dont have to rely on my parents for waterchanges

yay

Oh. Just had a look at the link in your last post (I'm a bit slow).

Don't see why the Aquapro wouldn't work. Cheap enough.

BTW Wallace & Gromit are brilliant - and their gadgets work! Ryan is the invention king - bet he's already figuring out how to do add a chemical dispenser to your system...

i have a series of 150 lt cubes

i run a 1500ltrper hour pump with 80cm head

when i do waterchanges it really does annoy me how long it takes

my opinion is to buy the biggest pump you can afford, preferrabley with a float sitch attached to it.

float switch can cost another 100-150 bucks to add on later so spend it now

the float will be invaluable in a upstairs / downstairs situation

Hey All, im looking for opinions on a topic...

Do you guys think a pump from a dishwasher would be of a food grade , and safe to use for a WC setup.. i can get my hands on a BEEFY pumo, ill give it a fire up tonight
