Product Overview
The seawater strainer is installed at the front end of the seawater system, mainly used to remove large impurities in seawater. It prevents impurities from damaging the seawater pump impeller, heat exchange equipment, or blocking the system flow path after entering the system, ensuring the normal operation of the seawater system and its heat exchange equipment. The seawater strainer is mainly composed of a shell, cover, filter basket, and sealing ring. Under the action of seawater pressure, seawater flows through the shell and filter basket of the strainer, and large particles in the seawater are removed by filtration. The particulate impurities are trapped inside the filter basket, and the filtered seawater flows into the pipeline system through the outlet for circulation.
This seawater strainer is suitable for front-end filtration of the seawater system of ships and is integrated with the seawater system pipeline.

Functional Features
-
The shell and upper cover adopt integrated casting forming technology, featuring good structural strength, strong impact resistance, and low leakage risk;
-
The filter basket adopts a basket-type structure, enabling fast and efficient disassembly and assembly, which is convenient for quickly lifting out and cleaning internal particulate impurities;
-
The strainer can be equipped with a differential pressure transmitter to monitor the clogging status of the strainer in real time, and an alarm signal will be sent out when the strainer is clogged;
-
The strainer can be equipped with an electrolytic anti-fouling device. During operation, copper ions are released by electrolysis to prevent marine organisms from adhering to the entire seawater system pipeline;
-
The interior of the strainer shell can be sprayed with insulating coatings such as ceramics to eliminate the potential difference between different metal materials of the strainer and reduce the potential corrosion of the internal flow components of the strainer.
