Fire Pump (Main + Emergency) · Pumps
Hamworthy (Waertsila) Hamworthy SF 50/20 — Pumps, fire. As a Fire Pump (Main + Emergency), 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 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. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
