D-D RO Booster Pump
Suitable for any brand of RO Unit - This pump will significantly increase the volume of water from your unit and will also increase the water quality.
Generally, RO units will run at about 50% of their stated membrane capacity as the temperature of the water is never 25C as the test is based on and the pressure is never as high as the standard.
By boosting the pressure with one of these units you tend to get the full stated membrane volume - summer or winter.
The increased pressure also improves the quality of the water through the membrane.
These units utilise a transformer to run at low voltage and are suitable for 1/4 inch RO Pipe.
Flow Rate (open flow) - 1.2lts/min
Pressure - 125 PSI (9 BAR)
Voltage - 24V
This pump is only suitable for membranes of 50-90 USG due to the flow rate of the pump and depending on the efficiency of the membrane/water temperature.
1.2 lts/min = 1728 lt/day = 455 USG/day
Flow rate must account for both collected and rejected water volumes through the RO unit.
If 4:1 reject rate = 455/5 = 91 USG
if 5:1 reject rate = 455/6 = 76 USG
We recommend that the pump is not used with any membrane over 100 USG/day as it will reduce the flow rate to the RO and will reduce the efficiency.
The pressure of 125PSI is the maximum pressure that the pump can produce when restricted however the larger the membrane the easier the water will flow and the less pressure will be produced.
NEVER DEAD HEAD THE PUMP FOR ANY TIME AGAINST A CLOSED SOLENOID OR CLOSED SHUT OFF VALVE AS THIS WILL DAMAGE THE DIAPHRAGM. IF THIS HAPPENS THEN A NEW HEAD IS AVAILABLE.
