Key Technical Advantages

• Axial Pressure Compensation: Featuring floating thrust plates that automatically adjust clearances via hydraulic feedback, maintaining over 95% volumetric efficiency throughout the pressure range.

• High-Load DU Bushings: Equipped with premium composite DU bearings, providing superior self-lubrication and radial load capacity, essential for high-pressure industrial cycles.

• Precision Gear Profiling: Gears are precision-ground and micro-profiled to minimize fluid pulsation, resulting in exceptionally low acoustic emissions in factory environments.

• Reinforced Sealing Architecture: The specialized high-pressure shaft seal is designed to withstand significant backpressure spikes, preventing leakage and ingress of environmental contaminants.

Application Areas

• Industrial HPUs: Powering automated assembly lines, hydraulic presses, and machine tool clamping.

• Mobile Auxiliary Power: Steering systems for forklifts and lift circuits for compact loaders.

• Material Handling: Main power source for electric pallet jacks and lift tables.

• Plastic & Die-Casting: Control circuits for auxiliary movements in molding machinery.

Expert Maintenance Tips

• Mandatory Pre-Filling: Never run the pump dry. Fill the unit with clean hydraulic oil through the inlet and rotate the shaft by hand before initial startup to ensure thrust plates and bearings are lubricated.

• Alignment Precision: Ensure the drive shaft alignment is within 0.05mm TIR. Misalignment is the leading cause of premature shaft seal failure and internal bearing stress.

• Filtration Vigilance: Maintain a fluid cleanliness level of ISO 4406 20/18/15. Regularly inspect suction strainers to prevent cavitation, which can cause immediate scoring of internal gear surfaces.
