The Importance of a Perkins Marine Raw Water Pump

Raw water pumps are not generic components—they are engineered specifically for marine applications and built to handle seawater exposure. For Perkins engines, this component plays a mission-critical role:

• Engine Cooling: Draws in seawater and circulates it through the engine’s cooling system.

• Performance Protection: Prevents overheating, which can damage cylinder heads, pistons, and gaskets.

• Marine-Grade Durability: Built to withstand constant contact with corrosive saltwater.

• Operational Reliability: Provides consistent flow at all engine speeds for stable performance.

Without a properly functioning raw water pump, a Perkins engine can quickly overheat, leading to expensive downtime or catastrophic failure.

Perkins Raw Water Pump Impellers

Every raw water pump depends on a properly functioning impeller. The impeller is a flexible rubber rotor with vanes that push seawater through the pump body. Over time, impellers wear down or crack, especially in harsh saltwater environments.

• Routine Maintenance: Impellers should be inspected at least once per season and replaced at the first sign of wear.

• Performance Protection: A worn impeller can reduce cooling efficiency, leading to overheating.

• Quick Replacement: Diesel Pro makes it easy to find the correct Perkins impeller for your specific pump and engine model.
