Buy SK220-3(MA340) SWING MOTOR Kato Pump Parts | Partsdic®

The swing motor Kato pump used in the SK220-3 (MA340) excavator is typically an axial piston motor.

This type of pump operates by converting hydraulic fluid pressure into rotational motion, facilitating the controlled rotation of the excavator's upper structure.

Flow Rate:
The flow rate of the swing motor pump determines the speed at which the excavator's superstructure can rotate. The exact flow rate may vary depending on the specific model and configuration, but it typically falls within the range of 50-100 liters per minute (LPM) for this class of excavator. A higher flow rate allows for faster and more powerful rotation.

Pressure Rating:
The swing motor pump generates hydraulic pressure to enable the rotation of the superstructure. The typical pressure rating for this pump ranges from 20-35 megapascals (MPa) or approximately 2900-5075 pounds per square inch (psi). Sufficient pressure is crucial for the excavator to handle heavy loads during swing movements effectively.

Control System:
The swing motor Kato pump is equipped with advanced control systems to regulate the direction and speed of rotation.

These controls allow the operator to precisely control the excavator's swing movements, ensuring safety and efficiency. The control system may include features like variable displacement, speed adjustment, and reversible rotation.

Reliability and Durability:
Reliability is paramount in heavy machinery, and the swing motor pump is designed to withstand the demanding conditions of construction and excavation work. It must endure exposure to dust, dirt, extreme temperatures, and heavy loads. High-quality materials and precision engineering contribute to the pump's durability.

Compatibility:
The swing motor pump is specifically designed to seamlessly integrate with the SK220-3 (MA340) excavator or similar machinery. Compatibility ensures that the pump functions effectively within the hydraulic system, allowing for smooth and controlled rotation.

Maintenance Requirements:
Routine maintenance is essential to ensure the longevity and optimal performance of the swing motor pump. Regular maintenance tasks include checking for leaks, inspecting hydraulic fluid levels, and monitoring the condition of seals and bearings. Proper maintenance extends the pump's lifespan and reduces the risk of unexpected failures.
