External Booster Pump For Water Purifier - How Do They Work?

When it comes to enhancing the efficiency of water purification systems, external booster pumps play a crucial role, but how exactly do they work, and do you need one for your reverse osmosis (RO) or RO/DI system? These are common questions that our customers often ask, and in this article, we'll delve into the workings of external RO booster pumps and their significance in water purification processes.

The Importance of Water Pressure in RO Systems

To comprehend the necessity of RO booster pumps, it's essential to understand how RO membranes operate. An RO membrane functions by compelling water through layers of membrane material, requiring adequate water pressure to ensure the purified water can be effectively pushed through these layers. The ideal pressure range for membrane operation falls between 65-80 PSI. Without a pressure gauge, it's advisable to add one to monitor and maintain optimal pressure levels.

While higher pressure enhances water production and membrane efficiency, exceeding 80 PSI can lead to over-pressure issues, such as leaks, valve problems, or ballooned membranes. On the other hand, low water pressure is a more common concern, resulting in slower water production and increased water wastage. If your water pressure is below 45 PSI, adding a RO booster pump becomes a recommended solution.

Addressing Water Quality and TDS Levels

Water quality is another factor influencing the need for a booster pump. If the Total Dissolved Solids (TDS) in your water exceed 500ppm, incorporating a RO booster pump is beneficial. It not only increases water production but also reduces water wastage, providing a more efficient purification process.

Unveiling the Inner Workings of RO Booster Pumps

A RO booster pump operates by utilizing diaphragms to elevate water pressure. The process involves water from the tap flooding the outer chamber of the pump. Inlet diaphragms draw water into a central chamber, while outlet diaphragms push water out of the pump's outlet. Visualize this as toilet plungers facing opposite directions, working in harmony to pull and push water, concentrating the water stream and boosting water pressure.

Most booster pump systems are equipped with pressure solenoids, ensuring the pump activates only when necessary. Our booster pump kits, for instance, include high-pressure solenoid switches that automatically shut off when you close the product water valve or when your water reservoir or drinking water bladder tank is full.

In addition to booster pumps, a pressure regulator is a valuable asset in optimizing water purification systems. It allows you to adjust the waste-to-product water ratio, helping fine-tune the operation of your system and minimize water wastage.
