Parts for Caterpillar 3508C – Marine Water Pump Section

The Caterpillar 3508C engine is a proven workhorse in marine environments, powering offshore supply vessels, tugboats, ferries, and heavy commercial ships. To keep this engine running at peak performance, a reliable cooling system is essential—and at the center of that system is the raw water pump. Diesel Pro Power provides operators with a complete catalog of raw water pumps, impellers, zinc anodes, silicone hoses, clamps, and related cooling accessories designed specifically for the Caterpillar 3508C.

Marine Raw Water Pump for Caterpillar 3508C

The raw water pump is responsible for pulling seawater into the engine and circulating it through heat exchangers, aftercoolers, and other cooling components. Without a properly functioning pump, overheating can occur, causing engine damage and costly downtime.

• Durable Marine Construction: Built for continuous-duty operation in demanding saltwater environments.

• Engineered for Reliability: Designed to handle high-volume water flow for the Caterpillar 3508C cooling system.

• Complete Assembly: Includes secure fittings and clamps for dependable installation.

A new or rebuilt raw water pump ensures consistent cooling, helping extend engine life and performance.

Marine Impellers for Caterpillar 3508C

The impeller inside the raw water pump is the heart of the cooling system. It rotates at high speed to move seawater efficiently through the engine.

• Bronze Construction: Resists corrosion and provides long service life in marine environments.

• 20-Blade Design: Ensures smooth, steady water flow to maintain proper engine temperature.

• Preventative Maintenance: Replacing impellers regularly avoids loss of cooling capacity.

An impeller change is one of the most important maintenance tasks for Caterpillar 3508C operators, preventing unexpected overheating events.

Zinc Anodes for Caterpillar 3508C Cooling Systems

Saltwater operation exposes cooling system metals to galvanic corrosion. Zinc anodes, often called “sacrificial anodes,” protect pumps, heat exchangers, and metal fittings from damage.

• Multiple Sizes Available: Small, medium, and large threaded zincs ensure complete coverage for the Caterpillar 3508C cooling system.

• Corrosion Defense: Absorb electrical currents that would otherwise corrode key components.

• Easy Replacement: Threaded design allows fast changes during routine maintenance.

Routine inspection and replacement of zinc anodes keep the raw water pump and heat exchangers protected, preserving both performance and longevity.

Silicone Coolant Hoses for Caterpillar 3508C

Hoses play an important role in connecting the raw water pump to the broader cooling system. High-quality silicone hoses are recommended for their superior durability.

• 4-Inch Diameter, 1-Foot Length: Fits Caterpillar 3508C cooling system connections.

• High-Temperature Resistant: Withstands higher heat than traditional rubber hoses.

• Marine-Grade Durability: Resists cracking, swelling, or collapsing under pressure.

Replacing hoses on a set maintenance schedule ensures leak-free operation and reduces the risk of cooling failure.

Marine-Grade Hose Clamps for Caterpillar 3508C

Hose clamps secure coolant and seawater lines against the vibration and pressure of continuous-duty operation. Diesel Pro Power supplies marine-grade clamps designed for different hose diameters.

• Variety of Sizes: From smaller fuel line clamps to heavy-duty options for large water hoses.

• Durable Stainless Steel: Built to resist saltwater corrosion and maintain strong clamping force.

• Leak-Free Connections: Designed to keep hoses tightly sealed, even under heavy vibration.

Clamps may seem small, but they are critical to preventing leaks and keeping the Caterpillar 3508C cooling system secure.

Marine Cables & Related Accessories

In addition to water pump components, Diesel Pro Power offers marine-grade control cables and accessories. These cables ensure reliable throttle and gear control in tough environments.

• Marine-Specific Construction: Designed for vibration, saltwater, and constant motion.

• Easy Integration: Compatible with Caterpillar 3508C installations.

• Durable Performance: Built to withstand continuous-duty operation.
