Product Description
High-Precision Spare Parts for KYB PSVL, PSVD2 & PSV2 Hydraulic Pumps
Product Overview: When your excavator experiences slow movement, unusual noise, or overheating, high-quality hydraulic spare parts are essential for restoring peak performance. We offer a comprehensive range of KYB axial piston pump spare parts, specifically engineered for the PSVL series (mini excavators), PSVD2-21 (integrated main pumps), and PSV2-55T (mid-sized excavators). All components are manufactured from high-hardness, wear-resistant alloys and undergo rigorous heat treatment, ensuring 100% compatibility with original units and significantly extending overhaul intervals.
Key Component Advantages:
Premium Material Engineering: Pistons feature high-strength bimetallic construction, and valve plates are precision-lapped to maintain minimal internal leakage even under high pressures of 31.5-34.3 MPa.
Complete Repair Solutions: We provide full rotating groups including Pistons, Cylinder Blocks, Valve Plates, Retainer Plates, and Ball Guides.
Optimized System Efficiency: Micron-level tolerance control ensures maximum volumetric efficiency, effectively resolving issues like “power loss when hot” and “slow cycle times.”
High-Temperature Sealing: Optional high-spec oil seals and O-rings provide excellent thermal resistance, preventing damage caused by case drain overheating.
Seamless Installation: Manufactured strictly to KYB factory specifications for rapid assembly without secondary machining, minimizing machine downtime.
