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

1. Principales caractéristiques et avantages

• 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.

• Capacité haute pression pour les travaux exigeants – Rated for continuous pressure of 34,3 MPa (≈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.

• Contrôle de puissance intégré à détection de charge – 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.

• Remplacement direct par boulonnage – 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.

• Pre‑shipment visual verification – 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.

• Livraison rapide – 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. Applications

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:

• Exploitation minière à ciel ouvert à grande échelle – 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.

• Carrières et granulats – 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.

• Construction lourde et infrastructures – 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.

• Démolition et traitement des ferrailles – 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.

• Entretien des parcs de location d'équipements – 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:
– Les La ligne de drainage du carter sur chaque pompe doit être dégagée et sans restriction. Un drainage du carter obstrué fera sauter le joint d’arbre instantanément au premier démarrage. doit être clair et sans restriction. Un drain de carter bouché ou plié créera une contre-pression à l’intérieur du boîtier de la pompe et fera sauter le joint d’arbre instantanément au premier démarrage.
– Avant d’installer la nouvelle pompe, rincez l’ensemble du système hydraulique et remplacez tous les filtres. Les contaminants d’une pompe défaillante détruiront une nouvelle pompe aussi rapidement qu’une ancienne – les débris ne font pas de discrimination.
– Après l’installation, faites tourner le moteur au ralenti bas pendant 2 à 3 minutes avec les pompes au point mort, puis actionnez lentement chaque fonction (flèche, bras, godet, rotation, déplacement) pour purger l’air du système.
– Après l’installation, faites tourner le moteur au ralenti bas pendant 2 à 3 minutes avec la pompe au point mort, puis actionnez lentement chaque fonction (flèche, bras, godet, orientation, déplacement) pour purger l’air du système.
– Vérifiez l’alignement de la pompe avec le carter du volant moteur – un désalignement provoque une usure prématurée des roulements et une fuite du joint d’arbre.
