Product details

9T-0290, 4T-6895, 6E-6272, 6E-5477, 6E-5965, 11026949 Hydraulic Piston Pumpsare a series of medium-pressure swashplate-type axial piston pumps. Below is a detailed introduction:

I. Product Features

1. Diverse Control Methods: These pumps offer various control modes, including constant pressure control, constant flow control, constant power control, and remote pressure regulation control, allowing for flexible adjustments based on actual needs.

2. Compact Structure: They feature a simple, compact, and lightweight design, facilitating easy installation and maintenance.

3. Superior Performance: These pumps operate quietly and have a long service life, meeting the demands of various complex working conditions.

4. Flexible Combination: They can be combined into tandem pump drives to enhance overall system performance and efficiency.

II. Application Fields

These hydraulic piston pumps are widely used in the following areas:

1. Metallurgical Machinery: Such as steel rolling mills and continuous casting equipment, which require high-pressure and stable-flow hydraulic systems.

2. Mining Machinery: Including excavators and loaders, which need reliable hydraulic power support under harsh working conditions.

3. Industrial Machinery: Such as presses and injection molding machines, which require precise flow and pressure control.

4. Construction Machinery: Including bulldozers and cranes, which rely on efficient hydraulic systems to perform various tasks.

III. Specific Models and Applications

1. 9T-0290, 4T-6895, 6E-6272, 6E-5477, 6E-5965, 11026949: These models share similar working pressures and speed ranges, with a displacement of 41ml/r, a working pressure of up to 210 bar, and a speed range of 2400 rpm. They are applicable to construction machinery such as D4H bulldozers, 65-85C excavators, 928 loaders, and D520 trucks.

2. PVE Series (e.g., PVE19, PVE21): These models also belong to the category of axial piston pumps, known for their high performance and reliability. They are suitable for construction machinery and agricultural machinery.

IV. Selection and Usage Recommendations

1. Select Based on Actual Needs: When choosing a hydraulic piston pump, determine the displacement, pressure rating, and control method based on the system's actual requirements.

2. Pay Attention to Installation and Commissioning: Ensure that the coaxiality error between the pump shaft and the driving motor is within the allowable range. Before the initial startup, fill the pump with oil and exhaust air to avoid dry friction.

3. Regular Maintenance and Upkeep: Regularly replace the hydraulic oil, monitor the pump body temperature and noise, and promptly investigate and address any abnormalities to extend the pump's service life.
