As the name implies, an automatic booster pump is a system designed to operate autonomously without requiring manual initialization after startup. Unlike a standalone booster pump, which cannot function on its own, an automatic system requires an intelligent controller along with additional components to manage the operation effectively. The controller serves as the central unit that governs the entire process, making it a crucial element in determining the system’s intelligence and reliability.
There are various types of controllers available, each with different operational mechanisms, but they all share a common working principle. Based on their method of control, they can be categorized into three main types: pressure-based, level-based, and frequency-based systems.
The level-based booster pump operates by monitoring the water level in a tank or reservoir. Once the water reaches a preset high level, the pump stops automatically. When the water level drops to a pre-set low level, the pump restarts, creating a continuous cycle of water supply. This system allows users to adjust the operating points by modifying the float position, offering flexibility in setting different levels for optimal performance. (See Figure 2 for the system diagram.)
In the differential pressure-based booster pump, the system monitors the pressure within the pipeline. When the pressure rises to a predefined upper limit, the pump turns off. Conversely, when the pressure drops below a user-defined lower limit, the pump restarts, maintaining a steady flow of water. The operating points can be adjusted by simply tuning the pressure gauge, making this system both intuitive and efficient. (Refer to Figure 3 for the system layout.)
The inverter-based booster pump uses a more advanced approach by continuously monitoring the pressure via sensors and sending real-time feedback to the controller. The controller compares the actual pressure with the user-set value and adjusts the pump speed accordingly to maintain a constant pressure. This ensures stable and energy-efficient water supply. Users can directly set any desired pressure value through the controller interface. (Figure 4 illustrates the inverter-based system configuration.)
Each type of automatic booster pump has its unique advantages, making it suitable for different applications depending on the specific needs of the system. Understanding these differences helps in selecting the most appropriate solution for reliable and efficient water boosting.
