What is true about the mesh size of discharge strainers compared to suction strainers?

Discharge strainers generally have a smaller mesh size compared to suction strainers. This choice is correct because discharge strainers are positioned downstream of pumps and other equipment where they help filter out impurities that could damage sensitive components such as valves and pumps. A finer mesh is required to catch smaller particles and ensure the system operates efficiently and effectively.

On the other hand, suction strainers are located at the intake of a pump and designed to allow larger particles to pass through while still protecting the pump from oversized debris that could cause damage or clogging. Given that the flow characteristics and operational priorities differ between discharge and suction sides, the mesh sizes reflect the need for more stringent filtration downstream versus more permissive filtration upstream.
