Kawasaki K3V280 Main Hydraulic Pump – Genuine New (9197075) for Hitachi ZAX870 / EX1200

1. प्रमुख विशेषताएँ और लाभ

• Genuine Kawasaki K3V280 main hydraulic pump – OEM part number 9197075, model K3V280SH140L-0E41-V. Manufactured by Kawasaki Precision Machinery (KPM), a global leader in hydraulic components for heavy equipment. This is a brand‑new, factory‑fresh unit – not remanufactured, not rebuilt.

• Engineered for Hitachi ZAX870 and EX1200 large excavators – Specifically designed for ZAX870‑3, ZAX870‑5G, ZX870‑3, ZX870‑5G, ZX850‑3, ZX650‑3, and EX1200 series excavators. This pump powers the boom, arm, bucket, swing, and travel circuits, delivering the massive flow and high pressure required for heavy mining, quarrying, and large‑scale earthmoving operations.

• K3V series – Kawasaki’s heavy‑duty hydraulic platform – The K3V280 is a variable displacement axial piston pump of swash plate design, specifically engineered for mobile applications such as excavators and cranes. Various rotary group layouts and tandem configurations are available to suit different applications. The K3V series is widely recognized as a reliable power source for construction machines.

• Massive flow for 80‑ton class machines – With a displacement of 280 cm³/rev, the K3V280 delivers approximately 520–560 L/min total flow from the main pumps at rated engine speed. This immense flow provides the hydraulic power needed for fast cycle times, high bucket fill factors, and responsive multi‑function operation.

• 适用于高要求作业的高压能力 – Rated for continuous pressure of 34.3 兆帕（约 4,975 psi） with peak pressure capability up to 39.2 MPa (≈5,685 psi) . Hitachi’s hydraulic systems typically operate at pressures up to 350 bar (≈5,076 psi). This pressure capability delivers consistent digging force, swing torque, and travel power hour after hour in the most demanding applications.

• 集成式负载敏感功率控制 – Features load‑sensitive control with stable pressure output and remote control variable pressure unloading and power control. The pump automatically adjusts flow to match actual working demand, reducing fuel consumption, preventing engine stall under sudden load, and extending the life of the entire hydraulic system.

• Exceptional durability and contamination resistance – Designed with robust construction for long service life even in harsh operating environments. Kawasaki KPM pumps are known for high efficiency, low noise, energy savings, and long service life.

• 直接螺栓固定替换 – Mounting flange, drive shaft spline, and hydraulic port configurations match the original Kawasaki K3V280 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 – Before packing, we send you detailed high‑resolution photographs of the actual unit (mounting flange, splines, port threads, castings, overall condition). You approve shipment – we never ship blind.

• त्वरित डिलीवरी – 1–3 working days lead time from our Guangzhou warehouse. Monthly supply capacity of 1,000 units, available for single‑piece or bulk orders.

2. अनुप्रयोग

The genuine Kawasaki K3V280 main hydraulic pump (9197075) is the power source for Hitachi ZAX870 and EX1200 excavators used in the most demanding heavy industries:

• 大型露天采矿 – 80‑ton class excavators are the backbone of copper, gold, iron ore, and coal mining operations. The pump’s massive flow (520‑560 L/min) delivers fast loading cycles while the high‑pressure capability (34.3 MPa) provides consistent digging force and swing torque hour after hour in remote mine sites where reliability is critical.

• 采石与骨料生产 – Loading trucks, stockpile management, and material handling in granite, limestone, and basalt quarries. The pump’s load‑sensitive control provides smooth, responsive operation for precise bucket control in abrasive dust conditions.

• 重型建筑与基础设施 – Dam building, highway cuts, tunnel portals, bridge footings, and large‑scale earthmoving projects. The pump’s ability to maintain consistent flow under varying loads ensures the excavator performs reliably throughout long shifts in exposed conditions.

• 拆除与废料处理 – Shock loads, vibration, and sharp debris are routine in demolition yards and metal recycling facilities. The Kawasaki K3V280 pump’s robust construction absorbs these extreme conditions without premature wear.

• 设备租赁车队维护 – 80‑ton excavators are high‑value rental assets. A genuine new pump provides predictable service life and eliminates the gamble of remanufactured or used units – avoiding costly mid‑rental failures, towing bills, and customer complaints.

• Energy & power generation projects – Pipeline construction, power plant earthmoving, and wind farm access road development. The pump’s high efficiency and low noise operation are advantageous in environmentally sensitive or noise‑restricted areas.

Critical installation tip for the K3V280 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.
