JMP ST series seawater strainers are designed to protect sea water pumps, marine engines and cooling systems from debris and impurities present in seawater.
The range is available with NPT connections, which refer to the tapered threaded standard of North American origin, or BSP connections, which refer to the British threaded standard widely used in Europe and in many international marine applications.
The series includes different models to suit various flow rates and marine applications. The robust bronze construction, transparent cylinder and chrome-plated stainless steel filter basket allow easy inspection, simple maintenance and reliable system protection.
JMP seawater strainers are suitable for marine engines, generator sets, sea water pumps and cooling systems where efficient and easy-to-check filtration is required.
