RO/DI booster pump

[Patis55]

So im in need of a booster pump for my new RO/DI unit but man the price of em seems high for what they are.
I have a 5 stage 50gpd with a added 50gpd membrane added. So 2 membranes.
Anyone ever come up with a different solution for a workable booster pump?

Aquatic Life Aquatic Life Smart Buddie Booster Pump for 50-100 GPD Reverse Osmosis Systems https://www.amazon.com/dp/B00OMBPNHI/ref=cm_sw_r_cp_api_Lnzkzb22ZGMG3

Very good pump, I using this one with the Aquatic Life 50GPD RODI unit. Im able to get 5 gallons every 50 minutes with this pump.

Yes, the RO/DI membrane run more efficiently with high pressure. 65 psi or higher is where you would like to be. Adding a booster would give you more efficiency with a higher GPH and you DI will last longer.

Looking at this pump. Has a cutoff switch and advertised at 81PSI, +/- 8PSI

if you look around ebay, you can find new chinese clone for around $60-70. Much cheaper than paying around $130-170 for booster pump. I've been using one since November and it's been working like a champ.
