http://www.machinemart.co.uk/shop/product/details/cbm240e-1in-multi-stage-230v-booster-pum?da=1&TC=RV-051011132

they are both the same spec but the cheaper one does'nt have automatic shut off

do you have one boosting pressure to a 4040 and at what pressure ? does it actually work ?

[David Kent @ KentKleen]

Sure have matey! boosts it up to 80 psi allthough i produce my best tds at 65 psi. 5000 ltr a week hasnt let me down been using it for 3 months

[Lee GLS]

kentkleen, what tds do you get with that booster pump on it? what is you tap pressure?

[Lee GLS]

is this the one?

do you know what its max pressure is?

[David Kent @ KentKleen]

I have a tap pressure of around 25. The max psi after pump is around 80.
At 60 to 65 psi i get a tds avarage of 007 and produce 1000 ltr in around 5 hours.
Hope this helps

[Lee GLS]

it most certainly does.

how long have you been using it, at £10 i wonder how long it would last.

also was that the right pump in the link?

[David Kent @ KentKleen]

using for 3 months. Thats the baby!! At £10 ive already had my moneys worth!! They where meant to be about £40 but they are selling them all off. Transfer pumps as well!! £10

[Topclean]

thanks for replys guys, kentclean what membranes you using will this do hf5? also would anyone no if i need a pump to use two di, one after the other?

Ive set up system with two ro 2 di and water seem to be backing up which i think is affecting the tds levels!

scratching head over this!

thanks in advance

[Topclean]

for that price its worth getting one anyway.

What size are the outlets?

[David Kent @ KentKleen]

Membranes are 'GE Systems'  Very old top quality and 'Keep on Going'

Sure have matey! boosts it up to 80 psi allthough i produce my best tds at 65 psi. 5000 ltr a week hasnt let me down been using it for 3 months

That B&Q pump is rated at 40 metre head, thats roughly 55 PSI. Its also not rated for continuous use.  You say your best TDS is at a lower pressure, that is certainley strange. I have two of these pumps and neither of them have got as powerfull as 50 PSI and thats trying them on two different systems. So my experience of these pumps is that not only are they not capable, they are (according to the literature) not up to the job. The ebay pump i quoted above well i have had one before and it pumped at 80PSI and was rated for continuous use. I've just ordered another one as i damaged my last one with the severe ice we had during the winter.
 I'm very happy with my two B&Q pumps as transfer pumps, they're great for the job. Not for pressure boosting though in my experience.

WHat pump you gonna go for now Topclean?

[David Kent @ KentKleen]

I suppose its down to set up hose size etc, mines running now at 65 psi and will be for the next 5 hours!
Running through pre filters that havnt been 'changed' for 18 months and  8 year old membranes! tds 007 checked 10 mins ago.
Tranfer using the same pump into van run it through twin  di vessels that have not had a resin change in 12 months water up pole and out of pencil jets = 000 (tds)
RO water can be cheap if you know what your doing

Yeah, i'm sure it is if you know what you're doing. And you're pumping more PSI than the pump is capable of, running through pre filters that should according to manufacturers been changed long ago, and into RO's that seem to have twice the lifespan of anyone elses. I'm just muckin about with the stuff really and i could do with spending a day with someone like you who knows what he's doing. Its costing me a fortune.

[David Kent @ KentKleen]

One of my best mates has just fit a £90,000 RO water install for a large chemical company. They produce 6 ton an hour at 000 tds.
He gives me all my tips Mike.
I am not trying to be clever just pointing out that with a bit of flushing here and a bit of soaking there you can get excellent almost free maintenance.
All the info i use is all available on the net for free!!!
Manufacturers like to sell you 'service' items.
Its like Car main dealers. You can do alot 'better' and cheaper service on your car yourself if you know what your doing.

I say "dont spend £200 on a pump when you can spend £10" 

[Topclean]

well here it is fellas, i like the sound of kentkleans pump but it is very cheap pump this concerns me a little as my last two membranes have only lasted me about 9 months each max! i have just purchased two new membranes and want these two to last a lot longer, not sure weather these pumps would kill the membranes sooner???

just not sure what to do!!

my current system does not run off a pump and it is now producing tds of 21 which in my opinion is not good enough! my pressure is only about 25 - 30 psi so i no a pump would be better just not sure what one.

it is all costing ££££££

THATS IT  B&Q   i,l let you now how it goes
