Coolant Pump (Part Number 3022474)

Coolant Pump

For Cummins NTA855 Series Engines

The Cummins coolant pump is a device installed on the diesel engine that circulates coolant through the engine to maintain its normal operation. The primary responsibilities of the pump are to generate circulation flow, circulate the coolant, and ensure unobstructed coolant passages.
∎ Flow Rate
The flow rate of a Cummins coolant pump refers to the volume of water it moves per minute, typically expressed in liters per minute (L/min) or gallons per minute (GPM). A higher flow rate means more coolant can be circulated through the engine and at a faster speed, ensuring proper engine operation.

∎ Head
Head refers to the resistance the Cummins coolant pump must overcome to ensure smooth coolant flow. A higher head allows the coolant to be circulated to areas further from the pump, providing better coverage of the entire engine.

∎ Pressure
The pressure of a Cummins coolant pump refers to the water pressure it generates, typically measured in psi or bar. Higher pressure allows the coolant to circulate through the engine faster, providing better protection.

∎ Speed
The speed of a Cummins coolant pump refers to its rotational speed in revolutions per minute (rpm). Higher speed results in faster coolant circulation, offering better engine protection.
