Key Technical Advantages:

Rapid-Response Displacement Regulation: Equipped with high-precision servo-valve control for swashplate angle adjustment, enabling displacement shifts in milliseconds. This dramatically enhances the response speed and smoothness of heavy machinery during multi-function operations.
Ultra-Wear-Resistant Piston Group: Piston bores and cylinder blocks undergo precision grinding and specialized nitriding, substantially boosting friction resistance. This ensures integrity under 400 bar extreme loads and prevents galling when paired with high-purity hydraulic fluid.
Low-Noise Fluid Dynamics: Optimized valve plate oil groove geometry significantly reduces pressure fluctuations during high-pressure discharge. This results in industry-leading noise performance, reducing high-frequency vibrations in the operator cabin.
Integrated Modular Design: The pump rear-end features multi-control valve interfaces and supports direct auxiliary pump mounting, offering a compact, space-saving solution for large-scale multi-circuit machines.

Application Areas:

Mining Machinery: Main hydraulic systems for large excavators, mine haulers, and crushing stations.
Construction Equipment: High-pressure concrete pumps, rotary drilling rigs, and heavy-duty cranes.
Industrial Hydraulic Systems: Injection molding machines, scrap metal shears, and large-flow hydraulic power stations.

Expert Maintenance Tips:

Cold Start Protection: When commissioning large displacement piston pumps in cold environments, always perform a no-load warm-up cycle for at least 10 minutes until oil temperature reaches 25°C. This ensures a stable hydrodynamic oil film forms between the pistons and valve plate.
Drain Port Requirements: The drain line must be routed directly back to the reservoir. Ensure the drain pipe diameter is never smaller than the housing drain port to maintain low case pressure; excessive case pressure can blow the shaft seal.
Fluid Cleanliness Standards: The PVG series is extremely sensitive to particulate contamination. We strongly recommend using 10μm return-line filtration and maintaining system fluid cleanliness at ISO 4406 18/16/13.

Vii. Precautions for Use

When installing, it is necessary to ensure that the flatness of the installation plane is ≤0.05 millimeters, and the coaxiality of the pump shaft and the drive shaft is ≤0.08 millimeters. Elastic couplings should be used for connection, and rigid connection is strictly prohibited. The oil suction pipe is selected as a short straight pipe with an inner diameter of ≥50 millimeters and a length of no more than 1.2 meters. A 120-mesh filter is installed. The oil suction port is ≥250 millimeters away from the bottom of the oil tank, and the oil suction resistance is ≤0.02 megapascals to prevent cavitation. The drain pipe should be connected to the oil tank separately, with a back pressure of no more than 0.1 megapascals. It must not be mixed with the return pipe. Before installation, it is necessary to confirm that the rotation direction is consistent with the equipment requirements to avoid installing it in the wrong direction and thus failing to supply oil.Before starting, check the oil level in the oil tank, fill the pump with clean and anti-wear hydraulic oil, and manually rotate the pump 3 to 4 times to ensure there is no jamming. After confirming the correct rotation direction through jog start-up, run it no-load for 10 minutes until the oil temperature rises above 35℃. Then gradually load it, with each pressure increase not exceeding 50 bar and an interval of no less than 3 minutes. Sudden loading to the rated pressure is strictly prohibited. During operation, monitor the oil temperature (normal 45-65℃, maximum not exceeding 80℃) and pressure (not exceeding 280 bar). If abnormal noise, vibration or leakage exceeds 2 milliliters per hour, stop the machine immediately for inspection.In terms of maintenance, check the oil level, oil temperature and sealing condition every 500 hours. Check the filter and replace the filter element every 1500 hours. When the oil contamination level exceeds the standard, replace the oil immediately and clean the system. Disassemble and inspect the wear of the plunger, sliding shoe and distribution plate every 2,500 hours. Replace the sealing parts in time if they are found to be aged or damaged. Hydraulic oils of different brands must not be mixed. In cold regions, the oil should be preheated to above 10℃ before starting.

It is strictly prohibited to start or operate without oil. Even short-term dry running (more than 3 seconds) can cause sintering damage to the plunger and cylinder block. It is prohibited to operate simultaneously at the highest pressure and the highest rotational speed for a long time. The cumulative duration of short-term peak pressure shall not exceed 50 hours. Before shutting down, the load should be unloaded to low pressure and run for 5 minutes. Only when the oil temperature drops below 60℃ should the power be cut off. For short-term storage (≤30 days), the oil port should be sealed and the vehicle should be turned by hand once a month. For long-term storage (>30 days), anti-rust oil should be injected, and anti-rust grease should be applied to the output shaft. Before reusing, replace the sealing parts and conduct a no-load test run for 3 hours.
