There is no exact official flow - rate value provided. However, in similar Komatsu engine - cooling - pump applications, the flow rate typically ranges from 80 - 250 cubic meters per hour. This range is crucial to ensure sufficient coolant circulation to meet the engine's cooling requirements and maintain its optimal operating temperature.
The actual flow rate can be affected by factors such as the pump's rotational speed, the diameter and length of the coolant hoses, and the resistance within the cooling system.
Head Pressure
For this type of engine - cooling water pump, the head pressure usually falls within the range of 15 - 60 meters. The working pressure generally does not exceed 1.2MPa. It's reasonable to assume that the head pressure of this water pump also lies within this range.
Adequate head pressure is vital as it enables the pump to overcome the resistance of the cooling system's components, including hoses, radiators, and engine passages, ensuring that the coolant is effectively distributed throughout the engine to dissipate heat.
Physical Dimensions
Overall Dimensions
Length: Exact length dimensions are not available. Commonly, the length of such water pumps for Komatsu engines can range from 300 - 500mm. The length measurement is crucial for installation as it determines how the pump fits within the engine compartment and whether it will interfere with other components.
Width: The width also lacks an exact measurement. Typically, the width of these pumps is around 150 - 250mm. The width dimension affects the pump's fitment and clearance requirements within the engine bay.
Height: There is no accurate height value provided. Normally, the height of these pumps is approximately 200 - 350mm. The height is an important factor for proper installation and to ensure there is sufficient space above and below the pump.
Installation Dimensions
Mounting Bolts: Specific details regarding the number of installation bolts, their diameter, and the bolt spacing are not available. Nevertheless, it's designed to match the mounting interface of the Komatsu PC300 - 6, PC340 - 6, PC350 - 6, S6D, and S6D108 engines precisely. This ensures a secure and accurate installation of the water pump onto the engine block.
