Pump Type: The main pump used in the KOBELCO SK250-8 is typically a variable displacement axial piston pump.
This type of pump offers efficient hydraulic power delivery, enabling precise control of the excavator's functions.
Flow Capacity: The flow capacity of the main pump determines the volume of hydraulic fluid that it can deliver per unit of time. The specific flow capacity of the pump for the SK250-8 may vary depending on the manufacturer and model of the aftermarket part.
Pressure Rating: The main pump must be able to generate the necessary hydraulic pressure to operate the excavator's functions effectively. The pressure rating refers to the maximum pressure that the pump can handle. Again, the precise pressure rating can vary depending on the specific aftermarket part.
Construction Material: The main pump components are typically made of high-quality materials to ensure durability and reliability. Common materials used in the construction of the main pump parts include stainless steel, cast iron, and various types of alloys.
Piston Type: The main pump features axial pistons that convert mechanical energy into hydraulic energy. These pistons move back and forth to create the pumping action. The exact design and specifications of the pistons can differ between different aftermarket parts.
Sealing Mechanism: Proper sealing is crucial to prevent hydraulic fluid leaks and ensure optimal pump performance. Various sealing mechanisms, such as O-rings or lip seals, are used in the main pump components to maintain fluid integrity.
Bearing Type: The main pump may utilize different types of bearings to support rotating parts and reduce friction. Common bearing types include ball bearings and roller bearings. The choice of bearing depends on the specific design of the aftermarket part.
Drive Mechanism: The main pump is driven by the engine or an auxiliary power source. The drive mechanism can involve various components, such as gears or belts, to transmit power from the engine to the pump. The specific drive mechanism details would depend on the aftermarket part.
Mounting Compatibility: When sourcing parts for the main pump, it is essential to ensure compatibility with the KOBELCO SK250-8 model.
