385B Hydraulic Pump K3V280DTH

The K3V280DTH is a model of hydraulic pump produced by Kawasaki Heavy Industries, commonly used in various heavy machinery including excavators like the Caterpillar 385B. As an axial piston pump, the K3V280DTH is designed to deliver hydraulic fluid under pressure to power various hydraulic systems within the excavator.

Here are some general features and specifications of the K3V280DTH hydraulic pump:

1. **Type**: The K3V280DTH is an axial piston pump, which means it operates by using a series of pistons arranged in a circular pattern around a central shaft. As the shaft rotates, the pistons reciprocate within their cylinders, drawing in and expelling hydraulic fluid to generate pressure.

2. **Displacement**: The displacement of the pump refers to the volume of hydraulic fluid it can deliver per revolution. The K3V280DTH typically has a displacement of 280 cubic centimeters per revolution (cc/rev), which determines the flow rate of the hydraulic system.

3. **Pressure Rating**: The pump is designed to operate within a certain pressure range, typically up to 350 bar (5,076 psi) or more depending on the specific model and configuration. This pressure rating ensures that the hydraulic system can generate sufficient force to operate the excavator's various functions.

4. **Control**: The hydraulic pump is controlled by the excavator's hydraulic system, which receives signals from the operator's inputs via joysticks or pedals. The control system regulates the flow of hydraulic fluid to the pump to adjust the speed and direction of hydraulic actuators.

5. **Efficiency**: The K3V280DTH pump is designed for high efficiency to ensure optimal performance while minimizing energy consumption. This helps to maximize the excavator's fuel efficiency and reduce operating costs.

6. **Durability**: The pump is built to withstand the rigors of excavator operation, including heavy loads, continuous use, and harsh working environments. High-quality materials and precision engineering ensure the pump's reliability and longevity.

7. **Maintenance**: Regular maintenance is essential to ensure the longevity and reliability of the hydraulic pump. This may include periodic inspections, lubrication, and replacement of worn parts as needed.

Specific details about the K3V280DTH hydraulic pump used in the Caterpillar 385B excavator, such as its exact specifications and technical details, would typically be found in the excavator's technical manual or specifications sheet provided by Caterpillar. If you require precise information about the 385B's hydraulic pump, consulting Caterpillar's official documentation or contacting their customer support would be the best course of action.
