What is the function of the transfer valve in the water pump?

The function of the transfer valve in the water pump is to manage the flow of water between series and parallel configurations in the pump system. When the pump operates in parallel, it allows for a larger volume of water to be delivered while maintaining a lower pressure. Conversely, when positioned in series, the valve enables higher pressure delivery for specific scenarios, such as when more reach is needed for hose lines or when supplying water to elevated structures.

This flexibility is crucial for addressing varying operational demands in firefighting scenarios, ensuring that firefighters can effectively manage water supply requirements based on the particular conditions they face. By facilitating this flow adjustment, the transfer valve enhances the overall efficiency and capability of the water pump in emergency situations.
