Resun pumps for sale to beat those electricity hikes.
The electricity consumption is a fraction of the more traditional pumps.
90 watts for 18 000 liters: PC 18 000
This one goes for R 1260.00.

Paul, het jy al gekyk wat maak die pomp as die hoogte waarheen die water gepomp moet word so 1.2m hoog is ?
Tans het ek 2 x 750W motors op my groot dam. Die een moet water ligna my filters toe (1.2m bo watervlak) en die ander een is omtrent 50cm bo watervlak en pomp direk terug na 7 return jets toe.
Wil graag laer wattage pompe gebruik en as dit moet, kan ek gat deurbreek in my eerste filter chamber in, maar wil nie graag nie want dan loop water terug in dam in indien die krag sou afgaan. Dit is om die rede wat ek graag sal wil weet of daar 'n groot verlies is indein dit so hoog gepomp moet word. 90 Watt is darem 'n helse klomp minder krag as 750W wat in my stelsel min of meer dieselfde werk behoort te doen

Hi Marius, sal more die flowchart pos. Dit le op die plaas.
Op 1.2 meter gaan die vloei seker ongeveer 30% verminder wat jou laat met 13 000 liter, maar laat ons eerder wag vir die flowchart.

Op 1,5 meter gaan die pc18000 so 11000Lt water pomp, hierdie pompe is rerig bedoel vir lae groot volumes maar daar moet geen restrieksies wees nie.
Dit klink vir my na die regte pomp om na te kyk in jou geval maar jy sal die huidige pyp deursnee moet vergroot en dit is n submercible, hy moet in die water staan.
Subject: Re: Low wattage pumps Thu Nov 04, 2010 4:10 pm
As jy kan wil jy nie asseblief ook die PG18000 se detail post hy is beter sover dit hoogtes aangaan, gebruik wel meer krag maar tog nog baie minder as die swembad pompe.
Subject: Re: Low wattage pumps Thu Nov 04, 2010 6:37 pm
Prys asb ?
Subject: Re: Low wattage pumps Thu Nov 04, 2010 6:43 pm
Het reeds 75mm pype op my bestaande pomp vir die filter chambers en daar min 'restrictions' deur filters tot by uitlaat na dam. Selfs twee van hierdie pompe gaan my 4keer minder krag kos en vloei behoort meer te wees as die 750W pomp. Die 'jet returns' werk met 50mm pype maar die 'head height' is minimaal met byna geen verliese behalwe die 'bends' na elk v d jets nie

I'm seriously considering this pump for my 12 000L also with waterfall. I'm still busy constructing but did'nt cater for the submersible pump but I definitely can make the adjustments now! I was advised earlier to consider using the submersible ... maybe I should listen!
Marius if you try this option keep us informed!!

Hehe ja Jaco brille en pille het hul voordele al kos dit meer as n pomp en n mooi koi
Subject: Re: Low wattage pumps Thu Nov 04, 2010 9:18 pm
Net gou onthou net dat hierdie pompe baie lae head het ne en n bend se weerstand word omgeskakel in head. So as jy bends het sal jy minder water kry.
Maar die goed gebruik so min krag dat jy gerus n tweede een kan insit sonder n probleem.
Ongelukkig gee die invoerders nie vir ons enige tegniese hulp nie en sal hulle ook geen rekomendasies of berekeninge vir ons doen nie. Ons sal maar net eenvoudig Trial en error way moet gaan.
Ek leer hard aan die storie en sal netnou ander pos vir julle om te sien sukkel bietjie met e-pos stuur.
Subject: Re: Low wattage pumps Fri Nov 05, 2010 9:42 am
Hiermee die flow chart soos belowe. Op 1.2 meter sal jou vloei wel ongeveer 13 000 liter wees.
Daar is ook 'n PC-36000 maar hy gebruik drie keer meer krag (280 watts) en voorsien slegs twee keer meer water en is dubbel die prys. (sien flow chart)
Dit is dus meer ekonomies om twee PC 18 000 pompe te hardloop as een PC 36 000. Indien die een 'n probleem ontwikkel het jy darem nog die ander een as backup. Om die rede installeer ek tans twee PC 18 000 pompe op my nuwe damme in plaas van een PC 36 000.

Hi Neville, ja, die PG 18 000 gebruik meer watts vir die dieselfde hoeveelheid watervloei alhoewel sy head 6 meter is. Hy is ook duurder.
Ek verkies die PC 18 000 weens die baie lae watts.
PC 18 000 90 watts - 18 000 liter - 3 meter head
PG 18 000 250 watts - 18 000 liter - 6 meter head

Thanks Jona, I will do that. The Qt is not a problem at all. I suck clean water from the far end of the filter system and it runs back via UV and waterfall. Head height to UV is maybe 20cm and the waterfall is about 50cm from pond water level.
In my large pond I pump to the filters, so I suck water from settlement chamber. Currently I have a Metala pre filter in chamber which I made myself (not going to pay R5600 for 4 pre-filters). The stuff you buy contains a green and blue sheet and some small particals reach my filters, so I made one with green and grey sheets (1.2m long and sheets more dense). It works very very good with almost no dirt entering the main filter sheets.
When I convert to the smaller pumps I need to modify the pre-filter part a bit to prevent the pumps clogging up. Should not be a major problem.
Dankie Paul, stem saam dat die 2 pompe beter keuse sal wees en ek glo dit sal perfek werk in my semi-gravity filter systeem.

Dit sal nice wees as jy en Marius vir ons n paar feite kan gee na julle installasies, ons het almal dit nodig.
Ek moet se dit wat ek gesien het van hierdie tipe pompe tot dusver het my nog nie te veel beindruk, hoop julle vaar beter
Ons wag roer julle.
Subject: Re: Low wattage pumps Sat Nov 06, 2010 5:16 pm
My sisteem sal teen die 18de werkend wees so sal dan post hoe myne werk. Ek het geen head op myne nie. Gaan ook die 90 bend op die pomp vervang met twee 45 bends om vloei te verbeter.

More is die groot dag vir aanskakel. Het 'n paar vertragings gehad.
Subject: Re: Low wattage pumps Fri Nov 26, 2010 6:33 am
Indication of the flow rate I received on my test run with one PC 18 000, outlet temporarily reduced to 50mm for the test. Will eventually not be reduced. (Not bad for 90 watts)
Subject: Re: Low wattage pumps Tue Dec 07, 2010 3:21 pm
The pumps are selling like hot cake. New consignment available on Monday.
I still have to do some changes on my new systems and neaten up, but currently one PC 18000 handles 20 000 liter with ease, at a fraction of the costs of my other ponds. (90 watts on pump + 30 watts on UV plus 60 watts on air compressor = 180 watts in total)
I have split the 75mm outlet into two 50mm outlets to enable me to fit a standard UV with 50mm connections. One line feeds a "bakkie shower" made of normal house gutters filled with zeolite. Two more gutters and a spray bar to be added above the top gutter and a bucket system bakkie shower to be added above settlement chamber.
I am sucking from my last chamber filled with 100 liters of kaldness(aerated) where most biological filtration will take place. Second chamber filled with heavy duty Japanese matting to act mainly as mechanical filtration and first chamber to be filled with brushes to assist with settlement of solids.
