Parts for Caterpillar C2.2 – Marine Water Pump Section

The Caterpillar C2.2 marine diesel engine is a compact, reliable power source widely used in smaller commercial vessels, yachts, fishing boats, and auxiliary systems. One of the most critical components in keeping this engine performing efficiently is its raw water pump system. The marine water pump ensures that seawater is drawn into the cooling system to regulate engine temperature, prevent overheating, and maintain optimal combustion efficiency.

Below you’ll find a complete catalog of Caterpillar C2.2 marine raw water pump parts, organized for easy navigation. Each component is engineered to meet or exceed Caterpillar specifications, providing durability and performance you can trust.

Marine Water Pump for Caterpillar C1.5 & C2.2 Engines

The primary raw water pump is the heart of the engine’s cooling system. It draws seawater through the intake and circulates it through the engine’s heat exchanger, ensuring consistent cooling under demanding marine conditions.

• Designed specifically for the Caterpillar C1.5 and C2.2 marine engines.

• Built with a mechanical seal that prevents leakage and ensures long service life.

• Precision-balanced impeller for optimal seawater flow and cooling efficiency.

• Constructed with marine-grade materials to resist corrosion from constant saltwater exposure.

Regular inspection of the water pump is essential. Over time, seals, bearings, and impellers wear down, and replacing the pump before failure can prevent costly overheating damage.

Impeller Puller for Marine Water Pumps

The impeller is the most frequently serviced part of the raw water pump. To remove and replace it efficiently, operators use an impeller puller.

• Designed for quick and safe impeller extraction.

• Prevents damage to the pump housing and impeller blades.

• Compatible with Caterpillar marine water pumps as well as Detroit Diesel and Cummins models.

Routine impeller inspection should be part of every maintenance cycle. A worn or cracked impeller can reduce water flow, leading to overheating.

Zinc Anodes for Caterpillar Marine Engines

Zinc anodes play a vital role in protecting the marine water pump and other metal cooling components from galvanic corrosion. In saltwater environments, dissimilar metals create electrical currents that corrode components over time. Zinc anodes act as “sacrificial metals,” corroding in place of your pump or engine.

Different zinc anode sizes and thread configurations are available to match various installation points on the Caterpillar C2.2 cooling system.

• Small Threaded Zinc Anodes – Compact design for smaller passageways, available in 1/4” NPT sizing.

• Medium-Length Zinc Anodes – Suitable for higher corrosion zones, available in 3/8” and 1/2” NPT with varying diameters.

• Heavy-Duty Zinc Anodes – Large 3/4” and 1 1/4” NPT designs for maximum corrosion resistance in high-salinity environments.

Routine inspection and replacement of zinc anodes are critical. Once the zinc is 50% consumed, it should be replaced immediately to ensure continued protection.

Silicone Coolant Hoses

While the raw water pump handles seawater, the engine also uses internal coolant hoses to circulate antifreeze through heat exchangers. Silicone hoses provide superior durability compared to standard rubber hoses.

• Resistant to high temperatures and pressure fluctuations.

• Available in multiple inside diameters ranging from 1” to 4”.

• Flexible construction makes installation easy in tight marine engine compartments.

• Resistant to cracking, hardening, and swelling caused by long-term coolant exposure.

Silicone hoses are an excellent upgrade for Caterpillar C2.2 owners seeking longer service intervals and reliability under demanding operating conditions.

Hose Clamps for Marine Cooling Systems

A secure cooling system depends on the right clamps. Diesel Pro Power offers marine-grade clamps designed to withstand vibration, salt exposure, and constant thermal cycling.

• Available in multiple effective diameter ranges to match all coolant and fuel hoses.

• Built with stainless steel for corrosion resistance in marine environments.

• Precision-engineered to maintain consistent pressure without damaging hoses.

Replacing worn or rusted clamps during maintenance is an inexpensive way to prevent costly leaks or engine overheating.

Gauges and Monitoring Systems

Monitoring your engine’s cooling performance is just as important as maintaining the pump itself. Diesel Pro Power supplies a range of mechanical and electric gauges for Caterpillar C2.2 operators.

• Mechanical gauges with optional alarms for direct and reliable monitoring.

• Electric gauges available in both 12V and 24V configurations.

• Designed for easy integration into marine dashboards.

A properly functioning gauge system allows operators to detect overheating or low pressure before damage occurs.

Marine Control Cables & Steering Components

While not directly part of the raw water pump, control cables and steering components ensure that marine operators can manage throttle and steering efficiently. Diesel Pro Power provides a wide selection:

• 33C and 43C marine cables for throttle and shift controls.

• Industrial cables for auxiliary equipment.

• Marine steering solutions designed for precision and durability in harsh conditions.

Integrating high-quality cables with a properly functioning cooling system ensures smooth vessel operation.

Additional Marine Accessories

To support a complete maintenance program for Caterpillar C2.2 engines, Diesel Pro Power also offers:

• Rubber Bearings – for propeller shaft alignment and vibration reduction.

• Searchlights and Navigation Lights – for marine safety compliance.

• Wipers and Marine Bulbs – to ensure clear visibility and operational reliability.

• Strainers – to prevent debris from entering the raw water pump and causing damage.

These accessories complement the water pump system by ensuring the entire engine environment remains protected and efficient.
