Caterpillar engines feature cutting-edge seawater cooling systems for high-end fuel efficiency and prolonged lifecycle. The integration with saltwater treatment eliminates the risk of corrosion in these models. Caterpillar 4361239 Auxiliary Water Pumps are among the top-rated parts to support operations without glitches for C32 engines.
Research reveals that using the best-in-class auxiliary cooling systems in marine vessels can save up to 4% of fuel based on annual consumption comparison.
In this blog post, we are dropping a guide to Caterpillar Auxiliary Water Pumps for C32 Engines. Explore the best models and alternatives to run your engine at its best.
Do Marine Cooling Pumps Use Seawater
Traditional cooling systems exposed seawater to engine components. This induces galvanic corrosion of engine machinery metals. The modern pumps integrate with the heat exchangers to regulate freshwater cooling. Contact with freshwater does not damage the engine parts. Seawater reduces the temperature of the freshwater in the heat exchanger by conduction.
Caterpillar modules feature integrated coolant inhibitor and chemical treatment systems to prevent corrosion of metallic parts in the vessel. Cat engines also allow the partial flow of seawater to gear oil cooling units.
