The Auxiliary pump is a component in marine engines, designed for cooling and maintaining optimal operating temperatures. It is used to circulate seawater throughout the engine's cooling system, ensuring efficient heat transfer and preventing overheating. It consists of several key components, including an electric motor, an impeller, a volute casing, and inlet and outlet connections. It is mounted in proximity to the engine, either directly on the engine or on a dedicated pump platform.

Attributes:
• Provide a sufficient flow rate of seawater.
• Withstands the corrosive effects of saltwater.
• Designed to resist high pressures and temperatures.

Applications:
The Auxiliary pump provides proper cooling of the engine, enabling extended operation in challenging conditions.
