What is Ro pump and how it is applied and described

The Ro pump, also known as a reverse osmosis booster pump, is a type of DC diaphragm booster pump. The Ro pump uses a DC motor as the power drive unit. The rotation of the motor’s rotor drives an eccentric rocker arm to perform eccentric motion, which converts into reciprocating motion of the three-cam water delivery frame assembly, driving the diaphragm to move back and forth, creating reciprocating suction on the valve cover. When the cam water delivery frame assembly moves downward, it creates a vacuum effect in the pressurization chamber, opening the check valve to draw in water. When the assembly moves upward, the water is compressed, the check valve seals, and the water is discharged into the high-pressure chamber, thus completing the water suction and pressurization process. The main types include high-pressure pumps, which directly provide working pressure for the Ro membrane, serving as the core power source of the system. Their characteristics include high head and high-pressure tolerance. Another type is the booster pump, which increases the pressure at the water intake end to assist the high-pressure pump.

The Ro pump is primarily used in reverse osmosis equipment for the water purification industry. It is one of the core components of a Ro water purifier, providing the necessary water pressure and flow rate for the operation of the Ro membrane, enabling the production of pure water. The pump has extensive applications in both industrial and civilian reverse osmosis water treatment systems, such as seawater desalination, brackish water desalination, industrial pure water preparation, and drinking water purification. By increasing the pressure, it provides power for the reverse osmosis membrane separation process, allowing water to pass through the membrane under pressure while impurities are retained, thus achieving the goal of water purification.
When the Ro pump is shut down for a long time, drain the water in the pump body and pipeline to prevent freezing or microbial growth and corrosion of parts. Store it in a dry and ventilated place to avoid rusting of motor or damage of electronic components caused by damp environment.
