There is no official exact flow rate provided. However, in similar Komatsu engine - cooling - pump applications, the flow rate generally ranges from 40 - 150 cubic meters per hour. This range is designed to ensure sufficient coolant circulation to meet the engine's cooling requirements. The actual flow rate may vary depending on factors such as the pump's rotational speed and the characteristics of the cooling system.
Head Pressure
For engine - cooling water pumps of this kind, the head pressure usually lies within the range of 10 - 40 meters. The working pressure generally does not exceed 1.0MPa. It's assumed that the head pressure of these water pumps also falls within this typical range. Adequate head pressure is necessary to overcome the resistance in the cooling system and ensure effective coolant distribution.
Physical Dimensions
Overall Dimensions
Length: Precise length values are not available. Commonly, the length of such water pumps for similar engines can range from 250 - 400mm. The length is an important factor for installation as it determines the space the pump occupies in the engine compartment.
Width: The width measurement is also not specified. Typically, the width of these pumps is around 120 - 200mm. The width affects the fit of the pump and the clearance it requires among other engine components.
Height: There is no precise height value given. Usually, the height of this kind of water pump is approximately 160 - 300mm. The height is significant for proper installation and to avoid interference with other parts.
Installation Dimensions
The details of the installation, such as the number of mounting bolts, bolt diameter, and bolt pitch circle diameter, are not available. But they are designed to match the mounting requirements of the Komatsu 4D95 and 3D95 engines to ensure a secure and accurate installation.
