Key Technical Advantages

Axial Clearance Compensation: Utilizes pressure-balanced floating bushings that automatically adjust the end-face clearance of the gears. This minimizes internal leakage and maintains stable flow even at 20 MPa pressure.
Reinforced DU Bearings: Equipped with high-capacity DU bushings optimized for frequent start-stop cycles and radial shock loads, significantly extending the service life of the drive shaft and gear set.
Precision-Ground Gear Sets: Manufactured from premium alloy steel with hardened surfaces and precision grinding, the gears ensure smooth engagement, reducing operational noise and pressure ripples.
Aerospace-Grade Aluminum Body: The extruded aluminum housing provides excellent heat dissipation and a lightweight profile, helping to control the hydraulic system’s operating temperature.

Application Areas

Agricultural Machinery: Tractor hitch systems, harvester auxiliary steering, and seeder drives.
Material Handling: Lift systems for 1-3 ton forklifts, hydraulic scissor lifts, and stackers.
Construction Equipment: Mini road rollers, street sweepers, and compact hydraulic power units.

Expert Maintenance Tips

Rotation Verification: Always verify the rotation direction before installation (CW for Right-hand, CCW for Left-hand from shaft view). Operating in the wrong direction will immediately blow out the shaft seal.
Inlet Integrity: Aluminum pumps are highly sensitive to cavitation. Regularly check the inlet port seals; air ingestion will cause loud whining noises and rapid wear of internal bushings.
Initial Priming: Never start the pump dry. Fill the pump with clean hydraulic oil through the inlet and rotate the shaft manually several times before starting the motor for the first time.
