Key Technical Advantages:

• Precision Gear Mesh Technology: Utilizing advanced gear-grinding processes, we optimize the tooth-mesh profile to significantly reduce pressure pulsation and mechanical noise, ensuring operational stability across the entire speed range.

• High-Strength Floating Side-Plates: Our unique floating compensation structure automatically adjusts axial clearance based on system pressure, drastically reducing internal leakage under high loads and boosting volumetric efficiency.

• Shock-Resistant Bearing Design: Equipped with heavy-duty needle bearings capable of withstanding high radial loads, ensuring the pump can effectively handle pressure transients inherent in hydraulic systems, extending service life.

• Modular Compatibility: Designed for direct replacement; every aspect—from port locations and mounting dimensions to drive shaft types—is engineered for a 1:1 match, ensuring “plug-and-play” installation without modifying existing plumbing.

Application Areas:

• Industrial Hydraulic Power Units: Machine tools, presses, injection molding auxiliary units.

• Mobile Equipment: Dump trucks, cranes, agricultural tractor hydraulics.

• Material Handling: Forklift hydraulics and lifting platforms.

• Municipal Maintenance: Refuse collection vehicles and street sweepers.

Expert Maintenance Tips:

• Port Protection: Never start the pump under load to avoid cavitation. Ensure the suction-side piping is airtight during installation to prevent air ingestion.

• System Cleanliness: Gear pumps are highly sensitive to contamination. We strongly recommend using 20μm (or finer) filters to maintain fluid cleanliness at ISO 4406 18/16/13 to protect the gear side-plates from wear.

• Periodic Temperature Monitoring: Operating temperatures should not consistently exceed 80°C. Excessive heat degrades lubrication, directly leading to accelerated gear wear and seal deterioration.
