Caterpillar 3412B Marine Raw Water Pump and Cooling System Components

Keeping your Caterpillar 3412B marine engine properly cooled is essential for long-term reliability and performance. The raw water pump is at the heart of this system, circulating seawater through the heat exchangers, aftercoolers, and other critical components. Diesel Pro Power provides a complete selection of raw water pumps and related cooling parts designed specifically for the Caterpillar 3412B.

Marine Water Pump for Caterpillar 3412B

The raw water pump is the key cooling component for the Caterpillar 3412B. Designed to handle continuous-duty marine applications, it ensures a steady flow of seawater through the cooling circuit. Its heavy-duty design supports the high horsepower output of the 3412B, whether installed in offshore vessels, commercial fishing boats, or tugboats.

Features of the Caterpillar 3412B raw water pump include:

• Durable marine-grade materials to resist corrosion from seawater exposure.

• High-capacity impeller design that maintains proper flow rate under heavy load.

• Flanged connections for secure integration into the cooling system.

• Direct compatibility with Caterpillar 3408 and 3412 engine families, ensuring reliability across platforms.

Impellers for Caterpillar 3412B Marine Water Pumps

Impellers are a vital service component of any raw water pump. They must be replaced regularly to maintain proper flow and prevent overheating. Diesel Pro Power offers premium bronze impellers designed for the Caterpillar 3412B:

• 20-Blade Impeller – Designed for stable, consistent water flow at various operating speeds.

• 32-Blade Impeller – Optimized for higher-capacity circulation, suitable for heavy-duty marine operations.

Both impeller options are precision-cast in bronze for durability, ensuring resistance against saltwater wear and extended service life.

Expansion Tank Gaskets for Caterpillar 3412B

A reliable gasket set is essential for maintaining the pressure integrity of the expansion tank and preventing coolant leaks. Diesel Pro Power offers gasket sets engineered specifically for the Caterpillar 3408 and 3412 engine families, ensuring a proper seal under continuous marine operation.

Zinc Anodes for Caterpillar 3412B Cooling Systems

Zinc anodes are sacrificial components that prevent galvanic corrosion inside your Caterpillar 3412B cooling system. Installed within the raw water circuit, they corrode instead of vital pump and engine components, preserving system integrity.

Diesel Pro Power provides multiple sizes and thread types to match the different fittings used in Caterpillar raw water pumps, expansion tanks, and heat exchangers. Options range from 1/4” NPT to 1-1/4” NPT, ensuring exact fitment. By replacing zinc anodes regularly, operators extend the lifespan of pumps, impellers, and heat exchanger cores.

Silicone Coolant Hoses for Caterpillar 3412B

Coolant hoses carry seawater and coolant through the Caterpillar 3412B’s cooling system. Diesel Pro Power stocks a wide range of silicone hoses in various diameters to fit the 3412B’s raw water and coolant lines.

Benefits of silicone hoses include:

• High heat resistance, preventing hose degradation in demanding environments.

• Flexibility and durability to withstand vibration and marine conditions.

• OEM-level fitment for Caterpillar 3412B cooling applications.

Hoses are available in diameters ranging from 1 inch to 4 inches, covering all major coolant and raw water connections.

Hose Clamps for Caterpillar 3412B

A secure cooling system requires clamps that can withstand vibration and pressure changes without loosening. Diesel Pro Power provides heavy-duty stainless-steel hose clamps for Caterpillar 3412B applications.

• Designed for long-term resistance to saltwater corrosion.

• Available in multiple ranges to fit small to large-diameter coolant hoses.

• Engineered for a tight, leak-free seal on silicone and rubber hoses.
