View Full Version : Should you get a booster pump?

Booster pumps make an incredible difference in the performance of RO systems.
Increased pressure dramatically increases the speed at which your RO membrane will produce purified water, and higher pressures result in RO water with lower TDS - which will increase the life span of your DI resin.

How much faster will a system with a booster pump produce water? Here's a couple of scenarios (from the calculator on our home page) as an example:
-75 gpd membrane at 38 psi and 65 degrees F water will produce 43 gpd, or 1.8 gph.
-75 gpd membrane at 80 psi and 65 degrees F water will produce 101 gpd, or 4.2 gph!

Here's some of our test data that illustrates the effect of increased pressure on rejection rate (the higher the rejection rate the more pure the RO water will be and the longer your DI resin will last):

We've been getting a lot of questions lately regarding how best to set up booster pumps and all the related components. By related components, we mean:
-Auto flush flow restrictor
-Float Valve
-High Pressure Switch
-Pressure Gauge
-Shut Off Solenoid

We put together the graphic below to help explain things.

if i am planning on using all the components

booster pump
pressure sens switch
auto flush
shut off solenoid

what wiring harness add ons do i need?

also how does the supply solenoid get actuated on and off? is the pressure switch controlling the booster, flush and solenoid all together???

You'll need one for the auto flush flow restrictor and for the shut off solenoid.

The pressure switch already has two plugs, and you can therefore plumb in only one item w/o a wiring harness/splitter, and that is the pump itself.

do you have everything in stock? also i can't find the auto flush on the site...

Here's an improved plumbing/wiring diagram. The wiring wasn't right in the diagam above:
