PSI at 60, do I need a Booster Pump

[Hair Algae Wizard]

Folks,

I have a 200gpd, 7 stage RO/DI system I purchased from Bulk Reef. My pressure meter is showing 59-60PSI, is this sufficient for effective use, or should I consider a booster pump?

Thanks in advance for any advice.

Following along. I have 7 stage 150 GPD running at 65 psi. Curious to hear others thoughts.

If it's a dual membrane setup like I think it is, I would highly suggest a booster pump. I have a dual 90GPD system and 85PSI going into the first membrane and only 45 going into the second. So I'd be willing to bet your second membrane is suffering from rather low PSI.

Product states 65-80 psi for optimal use/rejection rate. Maybe thing about that booster pump.

One thing to watch is if you do add a booster pump, make sure all chlorine is removed before entering your membrane. I had two 10” cartridges to remove chlorine / chloramines which worked fine until I increased the flow and there was not enough contact time. I have since added the chloramine blaster which is 4” x 20”

Thanks folks. I just ordered a booster pump. It's adjustable, so I can control the amount of pressure, and will keep it around 65-70 PSI.

I run a 4 stage at 60psi. Works well.

THe more stages the more pressure drop. The membrane needs ~ 50 PSI but if you have 3 stages (say sediment and 2 carbon blocks or vice-versa), and the incoming pressure is 50-60PSI, it will be far lower by the time it reaches a membrane, especially after few weeks of use.

Throw a gauge right before the membrane housing to see the actual pressure reaching the membrane.
