This water pump is specifically designed for the SK350 - 8 excavator model with the J08E engine. It is engineered to fit precisely into the engine's cooling system to ensure proper coolant circulation.
2. Flow Rate
The water pump is capable of delivering a certain flow rate of coolant. While the exact value may vary depending on factors such as the pump's speed and the resistance in the cooling system, it is typically designed to provide sufficient coolant flow to meet the cooling requirements of the J08E engine in the SK350 - 8 excavator. A typical flow rate could be in the range of several tens of liters per minute (e.g., 30 - 60 L/min), depending on the operating conditions and the engine's cooling demands.
3. Pressure Generation
It generates a certain amount of pressure to drive the coolant through the engine's cooling passages and the radiator. The pressure generated by the pump is usually in the range of a few tens of kilopascals (kPa). For example, it might produce a pressure of around 30 - 80 kPa to ensure effective coolant circulation against the resistance of hoses, the radiator, and other components in the cooling system.
4. Rotational Speed
The water pump is designed to operate at a specific rotational speed range that is synchronized with the engine's speed. The typical operating speed can vary from a few hundred revolutions per minute (rpm) at idle to several thousand rpm at full - throttle operation. For example, it may have an idle speed of around 600 - 800 rpm and a maximum speed of around 2000 - 2500 rpm, depending on the engine's characteristics and the gear ratio between the engine and the water pump.
