1. प्रमुख विशेषताएँ और लाभ

• 日立原厂OEM规格 – OEM part number YB60001891, HPK060 series. This is a brand‑new, never‑used main hydraulic pump, manufactured to Hitachi’s original factory standards for the ZAX130‑5A, ZAX130‑7, ZX130‑5A, ZX130‑5B, ZX130‑5G and compatible 13‑ton class excavators. Not remanufactured, not rebuilt – a factory‑fresh component with zero operating hours.

• HPK060 series – Hitachi’s 13‑ton class hydraulic platform – The HPK060 is a variable displacement axial piston pump engineered specifically for Hitachi’s medium‑size excavators. 。它为动臂、斗杆、铲斗、回转和行走回路提供精确流量和高压，以满足快速循环时间、平稳的多功能操作以及在重型建筑、采石和公用事业工作中的可靠性能。.

• 为 13 吨级性能提供充足流量 – The ZAX130‑5A hydraulic system features two variable displacement axial piston main pumps delivering a maximum combined flow of 2 × 117 升/分钟（总计 234 升/分钟） . The HPK060 is engineered to handle this flow, providing the hydraulic power needed for fast cycle times, high bucket fill factors, and responsive multi‑function operation – even when booming, swinging, and travelling simultaneously.

• 适用于高要求作业的高压能力 – 工作液压油路额定压力为 34.3 兆帕（约 4,975 psi） , with travel circuit also rated at 34.3 MPa and swing circuit at 32.3 MPa. This pressure capability delivers consistent digging force (104 kN bucket digging force), swing torque (34 kNm), and travel power hour after hour in the most demanding applications. The power boost function reaches 36.3 MPa for short‑term peak loads.

• Integrated HIOSIII hydraulic system control – The factory HIOSIII hydraulic system control ensures precise, predictable machine response – critical for precision grading, trenching near utilities, and fine attachment control. The system features a separate gear-type pilot pump delivering 33.6 L/min at 4.0 MPa (≈580 psi) for the joystick control circuit. A new genuine pump ensures all factory control parameters are maintained.

• Exceptional high pressure resistance – The HPK060 series is designed with excellent high pressure resistance, enabling the hydraulic pump to maintain a stable output even under extreme loads. This ensures consistent performance in the toughest working conditions without pressure drop or power fade.

• Designed for durability and low maintenance – Made of high‑quality materials and advanced manufacturing processes, the HPK060 hydraulic pump ensures a long service life and low maintenance costs. The corrosion‑resistant construction withstands harsh industrial environments and abrasive conditions.

• 直接螺栓固定替换 – Mounting flange, drive shaft spline, and hydraulic port configurations match original Hitachi specifications exactly. No modifications, no adapters – your mechanic unbolts the old pump and bolts this one in.

• 发货前可视化确认 – 在包装前，我们会向您发送实际泵体（安装法兰、花键、油口螺纹、铸件）的清晰高分辨率照片。您批准后，我们再发货。绝不盲目发货。.

• त्वरित डिलीवरी – 5–8 working days from our Guangzhou warehouse. Monthly supply capacity of 300 units.

2. अनुप्रयोग

The new genuine Hitachi HPK060 main hydraulic pump is the power source for ZAX130‑5A, ZAX130‑7 and 13‑ton class excavators used across a wide range of demanding job sites:

• 城市建设与公用事业 – Sidewalk repairs, water and gas line trenching, fibre‑optic cable installation, and small‑scale demolition in tight access spaces. The pump’s HIOSIII control provides precise, “fine‑touch” flow for delicate digging near existing utilities, while the high‑pressure capability (34.3 MPa) offers enough power for breaking compacted surfaces. The 13‑ton class machine with its 2 × 117 L/min flow handles these jobs with speed and efficiency.

• 住宅与商业开发 – Foundation digging, basement excavation, retaining walls, grading, and site preparation. The pump’s smooth response and quiet operation are essential for noise‑sensitive neighbourhoods. With a maximum flow of 234 L/min, the machine maintains fast cycle times even in multi‑function operations – booming, swinging, and travelling simultaneously without power loss.

• 道路与桥梁施工 – Shoulder repairs, drainage installation, guardrail replacement, and slope stabilisation. The pump’s ability to maintain consistent flow under varying loads ensures the excavator performs reliably throughout long shifts in exposed conditions. The ZAX130‑5A’s 70% gradeability is supported by the pump’s robust torque delivery.

• 采石与骨料生产 – Loading trucks, stockpile management, and material handling in abrasive dust conditions. The corrosion‑resistant construction withstands harsh environments, while the high‑pressure tolerance ensures consistent performance even under extreme loads. The pump’s durability and low maintenance design makes it ideal for high‑hour quarry operations.

• 矿山辅助作业 – Site cleanup, road maintenance, drainage works, and equipment pad grading. A new genuine pump with zero hours and factory tolerances provides predictable service life (typically 6,000–8,000 hours) – avoiding costly unplanned downtime in remote mine sites where service support is limited.

• 设备租赁车队 – 13‑ton excavators are among the most frequently rented machines. A new genuine pump eliminates the gamble of remanufactured or used units, offering predictable performance and reliability that keeps your machine on rent, not in the shop. The HPK060’s exceptional high pressure resistance ensures consistent performance across different operators and job conditions.

• 林业与植被清理 – Steep slopes, fallen timber, hidden obstacles. The integral HIOSIII control prevents engine stall under sudden load spikes, maintaining consistent power for saws, grapples, and mulchers. The pump’s stable output characteristics ensure reliable attachment performance even on challenging terrain.

• 农业与土地管理 – 排水沟清理、灌溉开沟、池塘维护和栅栏桩孔作业。该泵可调节的流量特性提供了精细园林绿化和重型农业机具所需的通用性。.

Critical installation tip for the HPK060 new pump:
– 壳体泄油管路 必须畅通无阻。堵塞或扭结的泄油管会在泵壳内产生背压，并在首次启动时立即损坏轴封.
– 在安装新泵之前，请冲洗整个液压系统并更换所有滤芯。来自故障泵的污染物会像损坏旧泵一样迅速地毁坏新泵——碎屑不分新旧.
– 在每个液压连接处使用新的 O 型圈和密封垫圈。重复使用密封件必然导致泄漏。.
– 安装后，在泵处于中位时让发动机以低怠速运转 2-3 分钟，然后缓慢循环每个功能（动臂、斗杆、铲斗、回转、行走）以排出系统中的空气。.
– 检查泵与发动机飞轮壳的对中情况——不对中会导致轴承过早磨损和轴封泄漏.
