GM Suction Strainer

A GM suction strainer is a type of strainer used in fire safety equipment, which is made of gunmetal (a type of bronze alloy). It is placed at the inlet side of a fire pump to prevent debris, rocks, and other materials from entering the fire pump and damaging it. The GM suction strainer is designed to filter out large particles and prevent clogging of the fire pump, thereby ensuring proper water flow and pressure during firefighting operations.
