Hi All

I have just ordered a hf5 4040 from gaps water, and was wondering if I cannot get enough pressure on-site would it be possible to use either a 60psi or 100psi shurflo pump as a booster pump?

[L.J.Thorpe]

if you have got one give it a try ,i bought a second hand booster pump off e bay for twenty quid and it does not look much different to a flojet or surflo,just make sure it does not run all the time,i use a timer plug with every other segment on so it gives 15 mins on 15 mins off this has really made a big differnce to how quickly i can produce water and how efficient the set up is

this sounds interesting, as I have an old shurflo pump and an hf5 myself
the ro is set up in my flat as a static (but no tank, I feed it straight to my van)
could I wire it to the mains by way of a transformer ? if so what would I need to do ?
would I put the pump after my pre filters ?

I guess you could try that.

I have a 300gpd atm with a booster pump and I fitted that after the pre filters, the sediment filter helps to protect it.

I guess for a test you could use your leisure battery to power the pump.

and then if that worked and you wanted something bit more permanent get something like this

I have a booster pump from pure-freedom but I dont think it will work with a 2500gpd system.

Done it with a 100psi shurflo and didnt work .... sorry to be the bearer of bad news

I have tried, but the flow rate was high and the pressure switch will cut the pump out.

[elite mike]

you could easily bypass pressure switch

ok thanks, but why do you think this was ? had you bypassed the pressure switch as elite mike had suggested or is it just not powerful enough given the size of the membrane ?

Did the same as blue frog 100psi shurflo 100gpd ro , no pressure switch ,.......DID NOT WORK !

i done it with one of these pumps temporarily for nearly 2 years  with the PS bypassed it worked perfectly

so if it can be done with this pump i cannot see why it cannot be done with the sureflow.
