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

1. Características y ventajas principales

• 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.

• Capacidad de alta presión para trabajos exigentes – 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.

• Control de potencia con detección de carga integrado – 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.

• Reemplazo directo atornillable – 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.

• Verificación visual previa al envío – 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.

• Entrega rápida – 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. Aplicaciones

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:

• Minería a cielo abierto a gran escala – 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.

• Canteras y áridos – 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.

• Construcción pesada e infraestructura – 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.

• Demolición y procesamiento de chatarra – 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.

• Mantenimiento de flotas de alquiler de equipos – 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:
– Los La línea de drenaje de la carcasa debe estar sin restricciones. Un drenaje bloqueado reventará el sello del eje instantáneamente en el primer arranque. debe estar despejado y sin restricciones. Un drenaje de carcasa bloqueado o doblado acumulará contrapresión dentro de la carcasa de la bomba y romperá el sello del eje instantáneamente en el primer arranque.
– Antes de instalar la bomba nueva, lave todo el sistema hidráulico y reemplace todos los filtros. Los contaminantes de una bomba averiada destruirán una bomba nueva tan rápido como una vieja: los residuos no discriminan.
– Use juntas tóricas y arandelas de sellado nuevas en cada conexión hidráulica. Los sellos reutilizados garantizan fugas.
– Después de la instalación, haga funcionar el motor en ralentí bajo durante 2-3 minutos con la bomba en punto muerto, luego accione lentamente cada función (pluma, brazo, cucharón, giro, desplazamiento) para purgar el aire del sistema.
– Verifique la alineación de la bomba con la carcasa del volante del motor; la desalineación causa desgaste prematuro de los cojinetes y fuga del sello del eje.
