Which component is found on the suction side of a centrifugal pump?

A strainer is indeed a component found on the suction side of a centrifugal pump. Its primary function is to filter out debris and particles from the fluid before it enters the pump. This is crucial because any contaminants can damage the pump's internal components, lead to reduced efficiency, or even cause a complete failure of the system. By ensuring that only clean fluid enters the pump, the strainer helps maintain the operational reliability and longevity of both the pump and the overall refrigeration system.

In a centrifugal pump, the impeller is located inside the pump and functions to impart energy to the fluid, facilitating its movement through the system. The pump motor is also located on the pump itself, driving the impeller and not classified as a suction-side component. The discharge valve is on the output side of the pump, controlling the flow of the fluid as it exits the pump. Thus, options related to the impeller, motor, and discharge valve do not pertain to the suction side where the strainer operates.
