Hitachi EX200-5 Główna Pompa Hydrauliczna – Remanufaktura z Chin (Montaż Hefei: 9150726 / 9152668)

Opis

Szczegółowe informacje

1. Kluczowe cechy i korzyści

• Precision‑remanufactured for Hefei‑assembled EX200‑5 – This twin pump set (9150726 / 9152668) is specifically rebuilt to Hitachi‘s factory specifications for the locally produced (Hefei) EX200‑5 excavator. Every critical component – cylinder block, piston assemblies, valve plate, swashplate, bearings, and seals – is either renewed or replaced with new, high‑quality parts. The result is restored hydraulic performance at a fraction of the cost of a new genuine pump set.

• Original Hitachi tandem axial piston architecture – The two pumps work together as a variable displacement tandem system, powering travel, swing, boom, arm, and bucket circuits independently. This design ensures smooth, coordinated multi‑function operation without internal flow loss – exactly as your EX200‑5 performed when it left the Hefei assembly line.

• Restored 20‑ton class power – After remanufacturing, the pump set delivers a rated working pressure of 31.9 MPa (≈4,630 psi) with intermittent peaks up to 34.3 MPa (≈4,975 psi). Combined flow is approximately 360‑400 L/min at rated engine speed. Your excavator regains full digging force, fast cycle times, responsive swing, and powerful travel.

• Zintegrowane sterowanie mocą z czujnikiem obciążenia – The factory power control (load‑sensing) system is completely rebuilt. It continuously matches pump output to actual working demand, reducing fuel consumption, preventing engine stall under sudden load, and extending the life of the entire hydraulic system. The integral pilot gear pump is also fully remanufactured.

• Cost‑effective alternative to new genuine – A new Hitachi main pump set for a 20‑ton excavator is a major investment. Our remanufactured 9150726 / 9152668 gives you the same fit, form, and function at a significantly lower price, without sacrificing reliability. Each pump is dyno‑tested before dispatch.

• Bezpośrednia wymiana typu bolt-on – Mounting flanges, drive shaft splines, and hydraulic port configurations are restored to original Hefei‑spec Hitachi dimensions. No modifications, no adapters, no fabrication – your mechanic unbolts the old pumps and bolts these in.

• Weryfikacja wizualna przed wysyłką – We send you clear, high‑resolution photographs of the actual remanufactured units (mounting flanges, splines, port threads, castings, overall condition) before packing. You approve shipment – we never ship blind.

• Szybka dostawa – 5–8 working days from our Guangzhou warehouse. Monthly supply capacity of 300 sets, available for single‑set or bulk orders.

2. Zastosowania

The remanufactured Hitachi 9150726 / 9152668 main pump set is ideal for the Hefei‑built EX200‑5 (20‑ton class) used in demanding job sites:

• Ciężkie budownictwo i infrastruktura – Highway excavation, dam building, bridge footings, large‑scale earthmoving. The restored tandem pumps deliver simultaneous boom, arm, and travel power without internal leakage – no power fade, no sluggish response, even on long shifts.

• Kamieniołomy i kruszywa – Loading trucks, stockpile management, and material handling in abrasive dust conditions. New bearings, seals, and wear plates ensure the pumps survive where worn units fail. Consistent flow and pressure mean faster cycle times and lower fuel consumption.

• Mining support – Site cleanup, road maintenance, drainage works, and equipment pad grading. The load‑sensing control reduces fuel burn during light‑duty cycles, saving money over thousands of operating hours.

• Rozbiórka i przetwarzanie złomu – Shock loads and vibration are routine. Our remanufacturing process replaces all wear components, restoring the pumps‘ ability to withstand harsh, unpredictable conditions.

• Floty wynajmu sprzętu – 20‑ton excavators are rental workhorses. A remanufactured pump set offers predictable service life (3,000–5,000 hours) at a cost that makes proactive replacement financially sensible – avoiding costly mid‑rental failures, towing bills, and customer complaints.

• – Leśnictwo i oczyszczanie terenu – Steep slopes, fallen timber, hidden obstacles. The integral power control prevents engine stall under sudden load spikes, maintaining consistent hydraulic power for saws, grapples, and mulchers.

3. Why Choose Części Hongtengda – Remanufacturing Without Compromise

At Hongtengda Parts, we have been remanufacturing hydraulic pumps for Hitachi excavators since 2001. We know that a main pump failure on your EX200‑5 stops your job site completely. Our remanufacturing process is not a “clean and reseal” – it is a factory‑grade restoration.

Our 6‑step remanufacturing process:

1. Całkowity demontaż – Each pump is stripped down to individual components: cylinder block, piston assemblies, valve plate, swashplate, bearings, shaft, housing, and control valves.

2. Czyszczenie i kontrola pęknięć – All parts are thoroughly cleaned and inspected for cracks using dye penetrant testing on critical castings. Irreparable parts are scrapped.

3. Wymiana elementów zużywających się – All seals, O‑rings, bearings, and gaskets are replaced with new. The cylinder block and valve plate are re‑ground to restore flatness. Piston assemblies are matched as a set and replaced if worn. The swashplate surface is reconditioned.

4. Precyzyjny montaż – Components are reassembled using OEM torque specifications. Clearance tolerances on the cylinder block / valve plate interface are verified.

5. Walidacja na stanowisku testowym hydraulicznym – The completed pump set is mounted to a test stand and run through its full pressure and flow range. We verify operating pressure (up to 31.9 MPa), flow rate (approx. 360‑400 L/min total), case drain leakage, and power control response. A test report is available upon request.

6. Końcowa kontrola jakości i pakowanie – The pumps are painted, fitted with protective port caps, and packed in a heavy‑duty wooden case for export.

Why our remanufactured pump outperforms cheaper “rebuilt” units:

• New bearings and seals – Many budget rebuilders reuse old bearings to save cost. We do not. All rotating components get new bearings – the single most important factor for pump longevity.

• Precyzyjnie szlifowane powierzchnie zużycia – The cylinder block and valve plate are re‑ground to restore flatness. A lapped surface is essential for low internal leakage. Without it, the pump will overheat and lose power within weeks.

• Full test report – Upon request, we provide a test report showing pressure, flow, case drain, and temperature measurements. You see the data before you buy.

Czego Państwo nie kupują: A used pump with new paint and a set of O‑rings. Our remanufactured pump set is restored to meet or exceed OEM performance standards – at a price that makes sense for your older EX200‑5.

• Ponad 25 lat doświadczenia w branży – Founded in 2001, we have remanufactured thousands of pumps for Hitachi, Caterpillar, Komatsu, Kobelco, Volvo, SANY, and many other brands.

• Dostępność 90% w magazynie – 9150726 / 9152668 pump sets are in stock as remanufactured units, ready for dispatch from our Guangzhou warehouse.

Critical installation tip for the 9150726 / 9152668 remanufactured pump set:
– Uszczelnienia pływające przewód spływu obudowy on each pump must be clear and unrestricted. A blocked case drain will blow the shaft seal instantly on first startup.
– Before installing the remanufactured pumps, flush the entire hydraulic system and replace all filters. Contaminants from the failed pumps will destroy a remanufactured unit just as quickly as a new one.
– Używaj nowych O-ringów i podkładek uszczelniających przy każdym połączeniu hydraulicznym. Ponowne użycie uszczelek gwarantuje wycieki.
– After installation, run the engine at low idle for 2–3 minutes with the pumps in neutral, then slowly cycle each function (boom, arm, bucket, swing, travel) to purge air from the system.
– Check pump alignment with the engine flywheel housing – misalignment causes premature bearing failure and shaft seal leakage.
