1.主な特徴と利点

• 日立純正OEM仕様 – 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. 本ポンプは、ブーム、アーム、バケット、旋回、および走行回路に、高速サイクルタイム、スムーズな複合動作、ならびに過酷な建設、採石、およびユーティリティ作業における信頼性の高い性能に必要な精密な流量と高圧を供給します。.

• 13トンクラスの性能を実現する十分な流量 – The ZAX130‑5A hydraulic system features two variable displacement axial piston main pumps delivering a maximum combined flow of 2 × 117 L/min（合計234 L/min） . 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.

• 過酷な作業に対応する高圧性能 – 作業油圧回路の定格圧力は 34.3 MPa（約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.

• 直接ボルトオン交換 – 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.

• 出荷前の目視確認 – 梱包前に、実際のポンプ（取付フランジ、スプライン、ポートねじ部、鋳造品）の鮮明な高解像度写真をお送りします。お客様が承認後、発送いたします。盲目的な出荷は一切行いません。.

• 迅速な配達 – 5–8 working days from our Guangzhou warehouse. Monthly supply capacity of 300 units.

2.アプリケーション

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:

• 都市建設およびユーティリティ – 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・商業開発 – 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・橋梁建設 – 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.

• 採石及び骨材 – 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.

• 鉱山支援 – 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.

• 機器レンタル事業者様向け – 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.

• 林業および植生除去 – 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.

• 農業・土地管理 – 排水路清掃、灌漑用溝掘削、池の維持管理、およびフェンス支柱用穴掘り。本ポンプの調整可能な流量特性は、繊細な造園作業から過酷な農業用アタッチメントまで、必要な汎用性を提供します。.

Critical installation tip for the HPK060 new pump:
– ケースドレンライン は、クリアで障害がない状態でなければなりません。ケースドレンが詰まったり屈曲したりすると、ポンプハウジング内に背圧が発生し、初回起動時に即座にシャフトシールが破損します。.
– 新品ポンプを取り付ける前に、油圧システム全体をフラッシングし、すべてのフィルターを交換してください。故障したポンプからのコンタミネーションは、古いポンプと同様に新品ポンプもすぐに破壊します – 異物は区別しません。.
– すべての油圧接続部に新品のOリングとシールワッシャーを使用してください。シールの再使用は漏れの原因となります。.
– 取付後、ポンプをニュートラルにしてエンジンを低アイドルで2～3分間運転し、その後各機能（ブーム、アーム、バケット、旋回、走行）をゆっくりと作動させ、システムからエアを抜いてください。.
– ポンプとエンジンフライホイールハウジングの芯合わせを確認してください – 芯ずれはベアリングの早期摩耗とシャフトシールからの漏れの原因となります。.
