Title: booster pump
Post by: Mike55 on November 07, 2010, 09:25:56 pm
Can I use a spare pump (shurflo 100psi) as a booster pump for the RO?  Or are the booster pumps different to these?

There is no reason why you cant use a shurflo pump but unsure how much they would really boost your water pressure,  TBH you'd be better off buying a proper 24/7 pump that was designed to pump water. you can get them from around £170 quid  ( cheaper for a draper made one )

Mine bumps my water pressure upto 70 psi for the Merlin and produces over 100 ltrs p/h

It's certainly more suitable than a sureflow, couldn't see a spec and unsure of how good the quality will be but should be good enough.

i got the top one on this page - they did the calculations so i got 70 PSI and i run this pump over night to fill 2 IBC's - it's never let me down.

If you used A normal sureflo pump it would keep dead ending so the pressure switch would kick in, thus acheiving nothing.

You can get a booster pump for under a 100.00 to boost upto a 500gpd.

I have an old shurflo pump and varistream set up to just boost as and when needed, works fine, my normal tds from membranes is 6 to 8 from 55psi water pressure, once boosted to 90psi the tds halves to 3 and pure production doubles. It's not something you should leave on all the time though .

I'm not o'fay with how to measure/work out fluids - APS just sorted for me - the pump you are looking at has a tank, so you are paying for that as well when it isn't required so the pump itself will be of a lower standard.

on the APS site they now do this...
Ebara JESXM5 230V Water Pump

at £118.00 + vat and it's stainless steel - this would be my choice.
