The pump assembly will automatically control standard residential reverse osmosis systems. The pump turns-on to produce water into the pressure tank, and then turns off when the pressure tank is full or when storage tank pressure reaches 40 psi. Benefits of using Booster pump for Reverse osmosis systems. For RO systems, an increased in input pressure means an increase in water production and water purity.
RO systems will run more efficient, and have less drain water. Since it uses pressure switch and solenoid valve to turn on/off the water input, it can turn-on and turn-off more accurately than the mechanical auto-shut-off valve. If you use large water container or open water tank, you can use float or level switches or float valves to control the operation of the pump as well. The transformer included in the package is.
Plugged into regular 110V/60HZ electrical outlet. More on how to adjust the boost pressure. You can use the pressure adjusting valve to fine tune the desired operating pressure.
For example, you have a 150GPD RO system and the water supply is 40 psi and drain rate is 850 mL/min. After the pump, the boost pressure could be 80 psi. So if you want to decrease the operating pressure to 70 psi, then you can turn the pressure adjusting valve slightly open (turn counter clockwise) If you want to further decrease the pressure, then you can turn the adjusting valve counter-clockwise.
So you can adjust the pressure between 40 to 80 psi. The boost pressure could be 90, 100+ psi depends on the flow rate of the pure water and drain water. The boost pressure could be only to 60 psi when it's approaching the pump's upper limit.
Such as 200GPD RO system or if the drain rate is over 1000 mL/min. NOTE : If you want to increase the boost pressure higher than the max. Pressure, you can make changes to the drain rate.
NOTE : This pump assembly is not a continuous duty. If you need to run the pump more than 4 hours, you can use a timer to turn on one hour and turn off for 1/2 hour to cool down the pump and solenoid valve, or you can put a fan to blow air into the pump assembly to cool down the pump. If input water pressure is about 30 to 40 psi, the pump will boost pressure to about 70 to 80 psi for RO systems. 2.3 liter per minute. Inlet and outlet, 3/8" FPT, or two 3/8"MPT to 1/4 compression fitting are included (connects to 1/4 tubing).Diaphragm pump, 3 chamber, self-priming. It is able to run dry.
