2. Core Product Advantages
20/925375 is the official JCB OEM part code matched exclusively with Nachi PVD-1B-24P-11AG pump. Overall structure, mounting dimensions and original hydraulic parameters are fully consistent with factory standards without mismatching problems after installation.
Adopts original Nachi constant power load sensing control mechanism, automatically adjusts pump displacement according to actual working load, effectively reduces idle power loss and optimizes fuel consumption performance of the whole mini excavator.
For refurbished pumps, all worn core components including piston shoe assembly, valve plate, swash plate, bearings and full seal kits are replaced with brand-new precision parts; calibrated via professional hydraulic test bench to maintain stable pressure output and low internal leakage during long continuous construction operation.
Unified mounting hole layout, oil port position and drive spline dimension support direct bolt-on replacement, no cutting, welding or extra mechanical modification required on equipment.
Equipped with high-temperature resistant, abrasion-resistant composite sealing assemblies to effectively block internal and external oil leakage under high pressure and frequent cyclic operation, prolonging the service life of the pump assembly.
Every finished pump undergoes strict pressure resistance test, flow calibration and sealing tightness inspection on dedicated test equipment before ex-factory delivery to reach original OEM technical indicators.
