Booster Pumps, need help!!!

BfishLpond78 · Apr 9, 2015

Hooked up my RO unit in the new house and water pressure is not so great since we are on a well. Goes between 40-55psi. Water barely dribbles out.

I have a 100gpd unit...what unit would you suggest I get?

I have the Aquatec 8800 Booster Pump from BRS and it works great!

Aquatec 8800 is the standard of the industry.

It may be the standard, but I didn't like it. Too much noise and vibration. Shurflo Gold is way way quieter for me.

Shur Flo is a good pump too. Don't know why you don't see many though. I have one in my RV for the delivey pump.

I didn't even know about Shur Flo pumps... Good info.

Get the 50GPD if you don't have 2 RO membranes. Go up to the 100GPD if you have 2 RO membranes, like I do.

I would look at Aqua fx. I bought a complete kit with pressure switch, power supply and adjustable flow rate. This pump is awesome. I run mine at 140 psi. Ten shy of my membranes capacity. I get the highest rejection rate that way. @ 60 psi you will only get 95% rejection and 80 psi is about 98% for a Dow filmtech
I high rejection rate on my setup. 1 tds before di and I have a well system too.

All in all you definitely need a booster pump. I recommend one even on city water. Most city is 70psi and that's just not a good enough rejection rate for me

It's not like AquaFX actually makes their own booster pumps

I do agree that a booster pump is a valuable addition. I'm on city water, and I was seeing 40-45psi at my first membrane. Now I'm at 60psi - 65 going into the first one. If I measured before the sediment filter, it would be higher.

Not sure what pump AquaFX uses but stick with the Aquatec 8800 or Shurflo. There are a lot of clones being imported that do not have the history and do not hold up as well. I get all my Aquatec pumps from Spectrapure and thy have them in a complete kit form too for like $140.
If you have a 75 GPD or larger membrane do not get the 50 GPD pump, it will overwork and burn out sooner. Look at the flow rate and match the pump to the RO including the waste flow too. The Aquatec 6800 will not keep up just as a smaller Shurflo will not either.

All your getting is 60 psi with a booster pump! Wow what did you buy. Is it adjustable. Not saying what you have doesn't work well but your di will thank you at a lower tds and a better rejection rate.

I get 140psi at the membrane and that's running it through the entire ro unit.

No Aqua fx did not make the motor but the had part in designing the pump head and the unit is branded to them. It is a high pressure pump.

Anyways off topic a bit. I recommend the Aqua fx package because it works well. You won't be sorry. You might want to try there high flow model and turn it down because you'll only get into the 80 psi range from 45. Wait you have a100gpd unit so yea you will want the high flow pump. And if you want better water I would go the extra so you can have some nice water and save on di.
It will be worth the $179 package which is real hard to beat for what you get
Call Aqua fx they are more than willing to talk to you to figure out the best solution for your needs. They have great customer service too. That's why I picked them after all my research to find the right setup.
