GUIDI Series 2000 seawater intake with integrated scoop strainer and thru-hull fitting is developed for maritime raw water installations where seawater must be safely routed through the hull of a boat. The intake can be used for, among other things, cooling water systems for engines and generators, watermakers, as well as toilet and sanitary systems.
The directional, scoop-shaped intake strainer acts as the first line of defense against plastic, marine growth, and other large debris. The hydrodynamic design is shaped to reduce pressure loss, turbulence, air bubbles, and the risk of cavitation. The strainer does not necessarily replace a downstream seawater filter.
The thru-hull fitting features a cylindrical G/BSPP pipe thread according to ISO 228/1, also designated BS 2779, and is available in several thread dimensions for various water requirements and system capacities. BSPP threads must be connected to compatible components and require a suitable gasket, O-ring, or sealant depending on the design of the installation. BSPP and NPT threads are not directly interchangeable.
The intake is mounted through a suitable hole in the hull and fastened from the inside with a nut and washer. The scoop opening must be oriented toward the bow and the vessel's direction of travel so that the water flow is correctly directed into the system. The recommended system layout is seawater intake, shut-off valve, seawater filter, and then the engine or other consumer.
Components in the seawater system should be made of compatible materials to limit the risk of galvanic corrosion. Where the installation permits, a separate GUIDI accessory can be used for bonding or equipotential bonding. The strainer must be checked and cleaned regularly for growth and debris with a suitable brush or high-pressure water.
The Series 2000 is a patented design with Lloyd’s Register Type Approval. The product can be recycled after dismantling.
