Our hydraulic seal kits and pump rebuild spare parts are specially designed for P365 series gear pumps. The full gear pump spare parts includes gear assemblies, bearing plates, drive shafts and complete oil seal sets. Made of wear-resistant alloy and oil-proof fluororubber, these parts withstand high hydraulic pressure with low friction loss. Precision CNC machining ensures 1:1 interchangeability with original components without modification. Widely used in construction and agricultural hydraulic machinery, they effectively fix pump leakage and pressure drop issues, cutting your equipment maintenance costs and downtime greatly.
We offer a comprehensive lineup of replacement spare parts compatible with all mainstream hydraulic gear pump models. Our product portfolio covers gear assemblies, sealing kits, bearing plates, drive shafts, pump housings and wear-resistant plates. Every component is manufactured from durable wear-proof alloy through precise CNC machining, delivering outstanding pressure resistance, minimal friction and extended service lifespan. Rigorous dimensional inspection guarantees full interchangeability with original factory parts. Suited for construction machinery, farm equipment and industrial hydraulic stations, our spare parts help clients slash maintenance expenses and minimize equipment shutdown periods.
