ONT 50-200

The Iron Pump ONT 50-200 is a centrifugal main cooling seawater pump that delivers high‑capacity seawater flow for engine and auxiliary system temperature control, featuring a robust cast‑iron casing with integrated sacrificial anodes. The supplied category identifies the equipment as Main Cooling Seawater Pump (Centrifugal), and it is normally installed in the engine room, pump room, cargo area or auxiliary machinery space within the service defined by the vessel piping arrangement. In that listed role, its primary purpose is to transfer liquid for the duty identified by the listed system. Centrifugal, screw, self-priming, progressive-cavity and service-specific pumps differ in hydraulic principle, suction behaviour and permissible media, so the exact construction must be confirmed from the installed documentation. The model designation identifies the listed configuration, but no additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. The source metadata also states power: 30.0 kW; capacity: 180 m3/h. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
