The impeller K 73106 is a critical rotating component of the raw water pump in the Sulzer/Adriadiesel/Jugoturbina/Zgoda ZV40/48 engine, responsible for generating the flow needed to circulate cooling seawater through the engine’s heat exchange system. Precision-machined for optimal hydraulic efficiency, the impeller ensures consistent water delivery even under varying engine loads. Manufactured from corrosion-resistant materials to withstand continuous exposure to seawater and mechanical stress, K 73106 supports stable engine temperatures, prevents overheating, and contributes directly to the reliability and longevity of the cooling system in demanding marine and industrial environments.
