Mud Box Cast Iron acc. to DIN

Marine Cast Iron Sediment Basket Strainer DIN

Basket strainer for seawater filtration in marine piping systems, manufactured to DIN 87151E, face-to-face per DIN 87151, flanges EN 1092-2 PN10, design pressure PN4, and tested according to EN 12266-1. Available in sizes DN40 to DN400.

Network Application

Installed in seawater service, cooling water, ballast, or auxiliary engine room circuits, upstream of pumps, heat exchangers, coolers, and equipment sensitive to sand, rust, organic debris, or solid particles.

Straight-through design is used where no change of flow direction is required at the filtration point. For installations with 90° flow change, an angle type basket should be considered.
