KOMATSU PC75UD-3 PC75US-3 PC75UU-3 PC78US-5 Hydraulic Pump 708-1W-00241 708-1W-00210 For Excavator Parts

Genuine & Refurbished Piston Pump for Excavator Replacement Parts

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
