Kawasaki K3V280DTH
This is the original Kawasaki K3V280DTH series dual-variable axial piston pump, custom-made for Sany SY750 (75-ton class) large excavators. It is also a universal configuration for XCMG 750 and other same-tonnage models.
Model Breakdown and Meaning
- K3V: Kawasaki Heavy-Duty High-Pressure Axial Piston Pump Series
- 280: Single pump displacement of 280 cm³/r, total displacement for dual pumps of 560 cm³/r
- D: Double (dual pump parallel structure)
- T: Tandem (tandem/parallel dual pump, suitable for large excavators)
- H: Negative flow control + constant power torque limit control (suitable for Sany system logic)
- Common full model suffixes: K3V280DTH1ZGR-0E92 or K3V280DTH-150R-ZP12-V
Core Technical Parameters
| Item | Parameter |
| Rated Pressure | 34.3 MPa (343 bar) |
| Peak Pressure | 39.2 MPa (392 bar) |
| Maximum Speed | 1800~2200 rpm (suitable for large excavator engine speeds) |
| Control Method | Negative Flow Control (NFC) + Constant Power / Torque Limit Control (TL) |
| Rotation Direction | Clockwise (shaft end view) |
| Weight | ~320 kg (dual pumps with regulator assembly) |
| Suitable Models | Sany SY750, XCMG XE750, etc., 70-80-ton class excavators |
Key Features and Advantages
1. Large Displacement High-Pressure Output: With an ultra-large single pump displacement of 280 cc, it provides ample flow for composite operations of boom, dipper stick, and bucket on large excavators, ensuring efficient heavy-duty operations.
2. Sany-Specific Control Logic: The DTH control scheme matches Sany's negative flow system, enabling precise flow distribution while balancing operational efficiency and fuel consumption.
3. High Reliability Structure: Adopting an inclined disk axial piston structure, core components (cylinder block, distributor plate, pistons) are original Kawasaki parts, offering impact resistance, wear resistance, and suitability for mining and heavy-duty conditions.
4. Universal Interchangeability: Can be replaced with same-spec K3V280 series pumps from XCMG 750, Hitachi EX3600, etc., making it a mainstream choice for large excavator hydraulic systems.
Common Faults and Maintenance Tips
- Weak operation/slow speed: First check if the regulator or solenoid valve is jammed, or if excessive internal leakage is caused by wear of the distributor plate or piston cylinder block.
- Stalling when hot, pressure not rising: Often due to excessively high hydraulic oil temperature reducing viscosity, or failure of the constant power control logic; check pilot pressure and main pump regulator.
- Maintenance Recommendations:
- Regularly replace hydraulic oil and filters to prevent pump wear caused by oil contamination.
- Ensure coaxiality of spline shaft and coupling during installation to avoid misalignment damaging the input shaft.
- Bleed air from new pumps as required to prevent dry running damage to pistons and cylinder blocks.
