Marine Raw Water Pump for Caterpillar 3056 Engines

The raw water pump is a critical component in the Caterpillar 3056 marine engine cooling system. It draws seawater into the engine’s heat exchanger to regulate operating temperatures, ensuring the engine runs efficiently and reliably even under heavy loads. A properly functioning seawater pump prevents overheating, safeguards cylinder liners, pistons, and cylinder heads, and extends the overall service life of the engine.

Marine Water Pump for Caterpillar 3054 & 3056 Engines and Perkins M92B
Heavy-duty marine seawater pump designed for long service life.
Gear-driven with 28 drive gear teeth for reliable performance in saltwater environments.
Built with corrosion-resistant housings and long-lasting seals to reduce the risk of leaks.

Impeller Tools & Maintenance Accessories

A seawater pump is only as reliable as its impeller. Over time, impellers wear out due to continuous contact with saltwater and debris. Diesel Pro Power carries all the maintenance tools you need to keep your Caterpillar 3056 running smoothly.

Impeller Puller for Marine Pumps
Designed to make impeller removal fast and safe, preventing damage to the pump housing.
Works with Caterpillar, Cummins, Detroit Diesel, and Volvo Penta raw water pumps.

Routine impeller inspections and timely replacements are essential for uninterrupted cooling performance.

Zinc Anodes for Caterpillar Marine Engines

Electrolysis and galvanic corrosion are major threats in marine environments. Zinc anodes are sacrificial components designed to protect the raw water pump, heat exchanger, and cooling passages from corrosion. Replacing zinc anodes at regular intervals is critical for preventing costly engine damage.

Available zinc anodes for Caterpillar 3056 raw water pumps include:

6L3014 Zinc Anode – NPT: 1/4”, Length: 1 1/2”, Diameter: 3/8”
6L2283 Zinc Anode – NPT: 1/4”, Length: 2 1/2”, Diameter: 3/8”
6L2280 Zinc Anode – NPT: 3/8”, Length: 1 5/8”, Diameter: 1/2”
6L2288 Zinc Anode – NPT: 1/2”, Length: 2 1/2”, Diameter: 5/8”
6L2289 Zinc Anode – NPT: 1/2”, Length: 3”, Diameter: 5/8”
6L2016 Zinc Anode – NPT: 3/4”, Length: 3/4”, Diameter: 3/4”
6L2284 Zinc Anode – NPT: 1 1/4”, Length: 2 1/8”, Diameter: 1 1/4”
6L2285 Zinc Anode – NPT: 1 1/4”, Length: 2 5/16”, Diameter: 1 1/4”

Each zinc is precision-machined to fit Caterpillar marine engines and ensures full protection in seawater applications.

Silicone Coolant Hoses for Caterpillar 3056

Silicone coolant hoses are essential for connecting the raw water pump, heat exchanger, and other cooling system components. Unlike standard rubber hoses, silicone hoses resist cracking, swelling, and heat degradation. They provide better durability in marine applications where exposure to high temperatures, salt, and vibration are constant factors.

Available diameters include:

All hoses are reinforced, pressure-rated, and built for long service in harsh conditions.

Clamps for Marine Cooling & Fuel Hoses

Every seawater pump system relies on secure hose connections. Diesel Pro Power supplies premium hose clamps that prevent leaks, withstand vibration, and resist corrosion.

Clamp options for Caterpillar 3056 include:

Effective diameter ranges from 9/16” to 3”.
Suitable for coolant and fuel hoses.
Built from marine-grade stainless steel for long-lasting service in saltwater environments.

Mechanical & Electric Gauges

Monitoring engine cooling performance is critical in marine operations. Overheating due to a failed seawater pump can quickly escalate into catastrophic damage. Installing or replacing gauges ensures operators are alerted to abnormal conditions before damage occurs.

Options include:

Mechanical Gauges (Standard or with Alarm)
Electrical Gauges – available in both 12V and 24V versions

These gauges provide accurate temperature and pressure readings, helping maintain optimal engine operation.
