A pump suction strainer, also known as an inlet strainer, serves as a crucial filtration device that connects to a pump’s inlet port, safeguarding the pump and the system from particulate damage or contamination. These strainers are integral components in various applications, such as paint guns, hydraulic machinery, fuel pumps, industrial cooling systems, and water treatment facilities.

Available in different configurations, some suction strainers are designed as inserts, while others feature inlet and outlet ports for direct installation at the pump head. Typically crafted from stainless steel to resist rust and corrosion, the suction screen or filtering element effectively captures and retains particles too large to pass through, while allowing the media to flow with minimal restriction.
