Where is the strainer located on a centrifugal pump?

The strainer in a centrifugal pump is located on the suction side. This positioning is essential for the effective operation of the pump. The primary function of the strainer is to filter out any debris or large particles from the fluid before it enters the pump. By doing so, it helps protect the pump components, particularly the impeller and volute, from potential damage that could be caused by these contaminants. Maintaining the integrity of the suction side with a strainer ensures a smooth operation and enhances the lifespan of the pump by preventing clogging and wear.

The discharge side is focused on directing the already pumped fluid out of the system and does not require filtration. The pressure side typically refers to the area where the fluid is under pressure after being pumped and is not involved in the initial intake process. A fluid reservoir is a storage component and does not contain the strainer inherently. Thus, the strainer's presence is critical on the suction side to protect the pump from impurities in the fluid.
