Why is an eccentric reducer utilized on the suction side of the pump?

An eccentric reducer is primarily utilized on the suction side of a pump to prevent air pockets from forming in the piping system. When fluid travels through piping, variations in pipe diameter can cause changes in fluid velocity and pressure. If a pipeline transitions from a larger diameter to a smaller one, the use of an eccentric reducer helps maintain a horizontal bottom plane in the piping. This design ensures that the lowest point of the pipe remains at the bottom, which is critical for preventing air from becoming trapped in the system. Air pockets can disrupt the flow of water and negatively affect the pump's performance, leading to cavitation and potential damage to the pump.

In contrast, the other options do not accurately describe the primary function of an eccentric reducer. While increasing flow rate, reducing pressure, or facilitating easier installation may be considerations in some contexts, they are not the primary reason for using an eccentric reducer specifically on the suction side of a pump. The focus is on maintaining a steady and uninterrupted flow of liquid, which is achieved through effective management of air and fluid dynamics within the system.
