Key Performance Advantages
High Power & Large Flow: Twin-pump parallel design delivers maximum flow output, meeting the demand for combined boom, arm, and bucket operations of large-tonnage excavators.
Precise Electronic Control: ECU-controlled variable mechanism adjusts flow in real time according to working conditions, balancing energy efficiency and operational responsiveness, reducing hydraulic shock.
High Reliability & Durability: High-strength cast steel housing and wear-resistant friction pairs (piston, cylinder block, valve plate) ensure long service life in harsh mining and infrastructure construction environments.
High Efficiency & Energy Saving: Volumetric efficiency≥92%, mechanical efficiency≥90%, reducing fuel consumption by 5-8% compared with traditional hydraulic pumps.
Perfect Interchangeability: Fully compatible with the original Kawasaki K5V212DPH structure, directly replaceable for excavators of SANY, XCMG, Kobelco, and other brands.
Application Scenarios
Excavator Main Pump: Core power source for 45–60 ton excavators, supporting digging, loading, crushing, traveling, and slewing operations.
Heavy Machinery Refit: Upgrading hydraulic systems for large loaders, cranes, and mining machinery.
Remanufacturing & Maintenance: Cost-effective alternative to original parts for equipment overhaul and life extension.
