Water pumping stations play a critical role in process industries, providing the necessary flow and pressure of water for various operations. Additionally, these stations are responsible for pumping out used water from the process. The backbone of pumping stations relies on electrical motors and Variable Frequency Drives (VFD), which serve as the reliable and essential components for their functioning.

Course Objectives:

Upon completion of this course, the participants will have basic knowledge of:-

Pump operation, series, and parallel pump operation.
