The feedwater pump plays a crucial role in a boiler system by supplying water to the boiler. This is essential for maintaining the proper water level within the boiler, which is necessary for safe and efficient operation. The feedwater must be supplied at a suitable pressure and flow rate, ensuring that the boiler can generate steam effectively. When water is turned into steam, it expands significantly, and without an adequate supply of water, the boiler could run dry, leading to overheating and potentially catastrophic failure. Therefore, the primary function of the feedwater pump is central to the overall operation and safety of the boiler system.
