- Main & Pilot Circuit Integration: Combines a high-flow main pump with a high-pressure pilot pump to supply independent fluid power for heavy earthmoving and precise machine control responsiveness simultaneously.
- Streamlined Tandem Layout: Eliminates the need for multiple independent pump setups, effectively minimizing mounting complexity and reducing required maintenance points.
- Heavy-Duty Earthmoving: Engineered for challenging mining and construction job sites, ensuring generous operational safety margins under peak heavy loads.
- Bulldozer Direct-Fit Replacement: Engineered strictly to original equipment specifications for a true drop-in installation without any mechanical modifications.
- Superior Pressure Tolerance: The auxiliary section safely tolerates pressures up to 300 kg/cm², ensuring continuous seal integrity and volumetric efficiency under peak stress.
- ISO-Standard Production: Sourced from a specialized Taiwan factory with documented R&D and strict QC protocols, delivering field-tested performance that matches the OEM.
- Lower Fleet Operating Costs: Offers highly competitive pricing over OEM distribution channels, allowing fleet managers to minimize unexpected downtime and lower the total cost of machinery ownership.
