Hitachi ZAX60 Główna Pompa Hydrauliczna – Regenerowana w Chinach (AP2D25 / 4663300)

Opis

Szczegółowe informacje

1. Kluczowe cechy i korzyści

• Professionally remanufactured to OEM specifications – This AP2D25 series hydraulic main pump (OEM 4663300) has been fully disassembled, cleaned, inspected, and rebuilt in our ISO‑certified facility in China. Worn components (cylinder block, piston assemblies, valve plate, swashplate, bearings, seals) are replaced with new, high‑quality parts. The result is a pump that delivers performance and reliability comparable to a new unit at a fraction of the cost.

• Original Hitachi AP2D25 tandem axial piston design – The AP2D25 is a variable displacement double (tandem) axial piston pump, combining two independent pumping units in one housing. This design powers the travel, swing, boom, arm, and bucket circuits simultaneously, providing smooth, coordinated operation for your ZAX60 (ZX60) excavator.

• Restored hydraulic power – After remanufacturing, this pump delivers rated working pressure up to 24.5 MPa (≈3,550 psi) and intermittent pressure up to 29.4 MPa (≈4,350 psi). Displacement remains 2 × 25 cm³/rev, restoring the original flow and torque characteristics of your machine.

• Zintegrowany system sterowania mocą (load-sensing) – Odbudowana pompa zachowuje fabryczny system sterowania mocą, który dopasowuje wydajność pompy do rzeczywistego obciążenia roboczego. Zmniejsza to zużycie paliwa, zapobiega zgaśnięciu silnika i wydłuża żywotność zarówno pompy, jak i układu hydraulicznego. Zintegrowana pompa zębata pilotująca jest również odbudowywana, aby zasilać obwód sterowania.

• Bezpośrednia wymiana typu bolt-on – The pump’s mounting flange, drive shaft spline, and hydraulic port configurations are restored to original Hitachi specifications. No modifications, no adapters, no fabrication – your mechanic unbolts the old pump and bolts this one in.

• Cost‑effective alternative to new genuine – A new genuine Hitachi main pump can cost thousands of dollars. Our remanufactured AP2D25 gives you the same fit, form, and function at a significantly lower price, without sacrificing reliability. Each pump is tested on a hydraulic test stand before dispatch.

• Weryfikacja wizualna przed wysyłką – Przed pakowaniem wysyłamy szczegółowe zdjęcia w wysokiej rozdzielczości rzeczywistej odbudowanej jednostki (kołnierz montażowy, wielowypusty, gwinty przyłączy, ogólny stan). Zatwierdzasz wysyłkę – nigdy nie wysyłamy w ciemno.

• Szybka dostawa – Czas realizacji 5–8 dni roboczych z naszego magazynu w Guangzhou. Miesięczna zdolność dostaw 300 sztuk, dostępne dla zamówień pojedynczych i hurtowych.

2. Zastosowania

The remanufactured AP2D25 hydraulic main pump is ideal for Hitachi ZAX60 (ZX60) excavators used in a variety of demanding job sites:

• Budownictwo miejskie i media – Sidewalk repairs, water and gas line trenching, fibre‑optic cable installation, and small‑scale demolition. The rebuilt load‑sensing control adjusts flow to match light‑duty cycles, saving fuel while maintaining precise control.

• Kształtowanie krajobrazu mieszkalnego i wykopy basenowe – Pool digs, retaining walls, grading, and drainage work. The tandem pump design allows independent flow to travel and attachment circuits, enabling simultaneous boom and bucket movements without power loss.

• Rolnictwo i gospodarka gruntami – Drainage ditch cleaning, irrigation trenching, pond maintenance, and fence post hole digging. The restored high‑pressure output provides the tractive force needed for pulling through soft, muddy fields.

• Wsparcie górnicze i konserwacja kamieniołomów – Site cleanup, drainage maintenance, equipment pad grading, and light aggregate handling. Abrasive dust and sharp rock fragments place heavy demands on pump seals and wear components; our remanufacturing process replaces all critical wear parts to withstand these harsh conditions.

• Utrzymanie floty wynajmu sprzętu – Midi excavators are frequent rental items. A failed main pump stops production. A remanufactured pump offers predictable service life (3,000–5,000 hours) at a cost that makes proactive replacement financially sensible, avoiding costly mid‑rental failures and customer complaints.

• Prace leśne i usuwanie roślinności – Steep slopes, fallen timber, hidden obstacles. The rebuilt power control system prevents engine stall when sudden load spikes occur, maintaining consistent hydraulic power for attachment operation.

• Utrzymanie dróg i mostów – Shoulder repair, guardrail replacement, drainage cleaning, and slope stabilisation. The restored tandem pump allows the operator to reposition the machine while operating the attachment – critical for roadside work with short work windows.

3. Why Choose Hongtengda Parts – Remanufacturing That You Can Trust

At Hongtengda Parts, we have been supplying and remanufacturing hydraulic pumps for excavators since 2001. We know that a main pump failure on your ZAX60 is a production‑stopping event. Our remanufacturing process is not a “clean and reseal” – it is a factory‑grade restoration.

Our 6‑step remanufacturing process:

1. Całkowity demontaż – The pump is stripped down to individual components (cylinder block, piston assemblies, valve plate, swashplate, bearings, shaft, housing).

2. Czyszczenie i kontrola pęknięć – All parts are cleaned and inspected for cracks or damage. Irreparable castings are scrapped.

3. Wymiana elementów zużywających się – The following are always replaced with new: all seals, O‑rings, bearings, and gaskets. The cylinder block and valve plate are re‑ground or replaced. Piston assemblies are matched and replaced as a set. The swashplate surface is reconditioned or replaced.

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 is mounted to a test stand and run through its full pressure and flow range. We verify operating pressure (up to 24.5 MPa), flow rate (approx. 110‑120 L/min), case drain leakage (must be within spec), and power control response.

6. Końcowa kontrola jakości i pakowanie – The pump is painted, fitted with port protection caps, and packed in a heavy‑duty wooden case.

Why our remanufactured pump outperforms cheaper “rebuilt” units:

• New bearings and seals – Many budget rebuilders reuse old bearings. We do not. All rotating components get new bearings.

• 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.

• Full test report available – Upon request, we provide a test report showing pressure, flow, and case drain measurements.

Czego Państwo nie kupują: A used pump with new paint and a set of O‑rings. Our remanufactured pump is restored to meet or exceed OEM performance standards – at a price that makes sense for your older ZAX60.

• 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 – AP2D25 series pumps are in stock as remanufactured units, ready for dispatch from our Guangzhou warehouse.

• Wysyłka w ciągu 24 godzin – Z naszego centrum w Guangzhou do Twojego spedytora w 1 dzień; zamówienia międzynarodowe wysyłane w ciągu 24 godzin.

• Weryfikacja wizualna przed wysyłką – We never ship a pump blind. You receive clear photos of the actual unit before packing – you approve, we ship.

• Wsparcie techniczne – Send us your ZAX60 machine serial number and a photo of the old pump. We confirm compatibility and provide installation guidance within 2 hours.

Send us your Hitachi ZAX60 machine serial number and a photo of the old pump – we will verify fitment, provide a quote, and document our pre‑shipment inspection within 24 hours.
