What is the main purpose of a booster pump in a water system?

The main purpose of a booster pump in a water system is to increase water pressure. This is particularly important in situations where the existing pressure is inadequate for the intended use, such as in multi-story buildings, irrigation systems, or in any application where water needs to be pushed over longer distances or to higher elevations. By increasing the pressure, a booster pump ensures that water flows effectively and at sufficient force to meet household or commercial demands.

The other functions listed, such as mixing chemicals, filtering contaminants, or regulating temperature, are associated with different equipment in water treatment systems. Mixing chemicals is typically handled by chemical injection systems, filtration is accomplished through various types of filters, and temperature regulation may involve heating elements or cooling systems, but they do not involve the primary role of a booster pump.
