Key Technical Advantages

• Axial Pressure Compensation: Utilizing floating bushings and pressure-balanced side plates, the pump automatically adjusts clearances based on discharge pressure, maintaining peak Volumetric Efficiency throughout its service life.

• High-Tensile Aluminum Body: Crafted from high-strength extruded aluminum with shock-resistant cast iron covers, the housing prevents distortion under extreme pressure cycles and offers superior heat dissipation.

• Premium DU Bushings: Equipped with high-capacity self-lubricating DU bearings, these pumps offer excellent radial support and friction reduction, significantly extending Long-life Durability.

• Precision-Ground Gears: Gears are manufactured from high-grade alloy steel with precision grinding and nitriding, resulting in ultra-smooth engagement, Low Noise Operation, and minimal pressure ripples.

Application Areas

• Material Handling: Primary steering and lifting pumps for 1-3.5 ton forklifts.

• Agricultural Equipment: Hydraulic lifting systems for tractors and harvesters.

• Compact Construction: Auxiliary hydraulic systems for mini-excavators and skid-steer loaders.

Expert Maintenance Tips

• Rotation Check: Always verify the rotation direction (L for CCW, R for CW) before installation. Incorrect rotation will cause immediate shaft seal failure.

• Filtration Standards: Maintain system filtration at $25\text{ }\mu\text{m}$ or better to protect the precision-compensated plates and extend internal component life.

• Pre-Lubrication: Manually fill the pump with filtered hydraulic oil through the inlet port before the first startup to prevent dry-running damage to the bushings and gear surfaces.
