- Manufactured strictly per original Komatsu OEM drawings and hydraulic parameters, perfectly matching the original hydraulic system of the four applicable machine models without system mismatching issuesmyKomatsu.
- Built-in load sensing pressure compensation structure automatically adjusts pump displacement according to actual working load, reduces ineffective power consumption and effectively lowers the overall fuel consumption of the excavator.
- For refurbished pumps, all worn core components (piston assembly, valve plate, swash plate, bearing, seal kits) are fully replaced with precision matched parts; professional bench calibration ensures stable pressure output and low internal leakage under long continuous heavy-load construction work.
- Consistent mounting flange size, oil port layout and drive spline specifiion support direct bolt-on replacement, no cutting, welding or other mechanical modifiion required on the equipment.
- High-temperature resistant composite sealing assemblies eliminate internal and external oil leakage under high pressure and frequent reciproing working conditions, extending the service cycle of the hydraulic pump assembly.
- Each finished pump is tested through pressure endurance test, flow calibration and overall tightness inspection on a dedied hydraulic test bench before delivery to meet OEM performance standards.
