Hitachi ZAX60 Hoofdhydrauliekpomp – China Gereviseerd (AP2D25 / 4663300)

Beschrijving

Detail Informatie

1. Belangrijkste functies en voordelen

• 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.

• Geïntegreerd vermogensregel- (lastvoelend) systeem – De herbouwde pomp behoudt het fabrieksvermogensregelsysteem, dat de pompoutput afstemt op de werkelijke werklast. Dit vermindert het brandstofverbruik, voorkomt motorstalling en verlengt de levensduur van zowel de pomp als het hydraulische systeem. Een integrale hulproetorpomp wordt ook herbouwd om het regelcircuit te voeden.

• Directe bout‑op vervanging – 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.

• Kosteneffectief alternatief voor nieuw origineel – 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.

• Visuele verificatie voor verzending – Vóór het verpakken sturen wij u gedetailleerde hoge-resolutiefoto's van de daadwerkelijke gereviseerde eenheid (montageflens, vertandingen, poortdraad, algemene staat). U keurt de verzending goed – wij verzenden nooit blind.

• Snelle levering – 5–8 werkdagen levertijd vanuit ons magazijn in Guangzhou. Maandelijkse leveringscapaciteit van 300 eenheden, beschikbaar voor enkele of bulkbestellingen.

2. Toepassingen

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

• Stedelijke bouw & nutsvoorzieningen – 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.

• Residentieel landschapsontwerp & zwembadgraafwerk – 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.

• Landbouw & grondbeheer – 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.

• Mijnbouwondersteuning & steengroeveonderhoud – 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.

• Onderhoud van materieelverhuurvloot – 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.

• – Bosbouw en vegetatieruiming – 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.

• Weg- & brugonderhoud – 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.

Ons 6-stappen revisieproces:

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

2. Reiniging & scheurinspectie – All parts are cleaned and inspected for cracks or damage. Irreparable castings are scrapped.

3. Vervanging van slijtagecomponenten – 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. Precisie hermontage – Components are reassembled using OEM torque specifications. Clearance tolerances on the cylinder block / valve plate interface are verified.

5. Validatie op hydraulische testbank – 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. Eindkwaliteitscontrole & verpakking – The pump is painted, fitted with port protection caps, and packed in a heavy‑duty wooden case.

Waarom onze gereviseerde pomp beter presteert dan goedkopere “herbouwde” eenheden:

• Nieuwe lagers en afdichtingen – Many budget rebuilders reuse old bearings. We do not. All rotating components get new bearings.

• Precisiegeslepen slijtoppervlakken – 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.

Wat u niet koopt: 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.

• 25+ jaar industriële ervaring – Opgericht in 2001, hebben wij duizenden pompen gereviseerd voor Hitachi, Caterpillar, Komatsu, Kobelco, Volvo, SANY en vele andere merken.

• 90% voorraadbeschikbaarheid – AP2D25 series pumps are in stock as remanufactured units, ready for dispatch from our Guangzhou warehouse.

• 24-uurs verzending – Van ons Guangzhou-hub naar uw expediteur in 1 dag; internationale bestellingen worden binnen 24 uur verzonden.

• Visuele verificatie voor verzending – Wij verzenden nooit blind een pomp. U ontvangt duidelijke foto's van de daadwerkelijke eenheid vóór het verpakken – u keurt goed, wij verzenden.
