1. Características y ventajas principales

• Especificación OEM original de Hitachi – 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. Alimenta los circuitos de pluma, brazo, cuchara, giro y desplazamiento con el caudal preciso y la alta presión requeridos para ciclos rápidos, operación multifunción suave y rendimiento confiable en trabajos pesados de construcción, canteras y obras de servicios públicos.

• Caudal sustancial para rendimiento de clase de 13 toneladas – The ZAX130‑5A hydraulic system features two variable displacement axial piston main pumps delivering a maximum combined flow of 2 × 117 L/min (234 L/min en total) . 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.

• Capacidad de alta presión para trabajos exigentes – Clasificada para una presión del circuito hidráulico de trabajo de 34,3 MPa (≈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.

• Reemplazo directo atornillable – 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.

• Verificación visual previa al envío – Le enviamos fotografías claras y de alta resolución de la bomba real (brida de montaje, estrías, roscas de puertos, fundiciones) antes del embalaje. Usted aprueba, nosotros enviamos. Nunca a ciegas.

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

2. Aplicaciones

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:

• Construcción urbana y servicios públicos – 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.

• Desarrollo residencial y comercial – 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.

• Construcción de carreteras y puentes – 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.

• Canteras y áridos – 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.

• Apoyo minero – 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.

• Flota de alquiler de equipos – 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.

• Despeje forestal y de vegetación – 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.

• Agricultura y gestión de tierras – Limpieza de zanjas de drenaje, zanjeo para riego, mantenimiento de estanques y agujeros para postes de cercas. Las características de caudal ajustable de la bomba proporcionan la versatilidad necesaria tanto para paisajismo delicado como para accesorios agrícolas pesados.

Critical installation tip for the HPK060 new 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.
