Hitachi ZAX60 Ana Hidrolik Pompası – Çin Yeniden Üretimi (AP2D25 / 4663300)

Açıklama

Detay Bilgiler

1. Temel Özellikler ve Faydalar

• 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.

• Entegre güç kontrolü (yük algılamalı) sistemi – Yeniden inşa edilen pompa, pompa çıkışını gerçek çalışma yüküyle eşleştiren fabrika güç kontrol sistemini korur. Bu, yakıt tüketimini azaltır, motorun stop etmesini önler ve hem pompanın hem de hidrolik sistemin ömrünü uzatır. Kontrol devresine güç sağlamak için entegre bir pilot dişli pompası da yeniden inşa edilir.

• Doğrudan cıvatalı değiştirme – 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.

• Yeni orijinale uygun maliyetli alternatif – 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.

• Pre‑shipment visual verification – Paketlemeden önce, yeniden üretilmiş ünitenin (montaj flanşı, kamalar, bağlantı dişleri, genel durum) ayrıntılı yüksek çözünürlüklü fotoğraflarını size göndeririz. Sevkiyatı onaylarsınız – asla körlemesine sevkiyat yapmayız.

• Hızlı teslimat – Guangzhou depomuzdan 5–8 iş günü teslim süresi. Aylık 300 adet tedarik kapasitesi, tek parça veya toplu siparişler için mevcuttur.

2. Uygulamalar

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

• Kentsel inşaat ve altyapı – 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.

• Konut peyzajı ve havuz kazısı – 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.

• Tarım ve arazi yönetimi – 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.

• Madencilik desteği ve taş ocağı bakımı – 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.

• Ekipman kiralama filosu bakımı – 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.

• Ormancılık ve bitki örtüsü temizliği – 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.

• Yol & köprü bakımı – 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.

6 aşamalı yeniden üretim sürecimiz:

1. – Ünite, ayrı bileşenlere ayrılır: yatak kafesleri, planet taşıyıcılar, halka dişliler, mil, piston bloğu, silindir namlusu, valf plakası, hidrolik motor bölümü ve fren paketi. – The pump is stripped down to individual components (cylinder block, piston assemblies, valve plate, swashplate, bearings, shaft, housing).

2. Temizlik ve çatlak kontrolü – All parts are cleaned and inspected for cracks or damage. Irreparable castings are scrapped.

3. – Aşağıdakiler her zaman yeniden kullanılmamak üzere yenileriyle değiştirilir: tüm contalar, tüm o-ringler, tüm salmastralar, tüm makaralı yataklar, komple piston/kayıcı takımı, silindir namlusu aşınma plakası ve valf plakası. – 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. Hassas yeniden montaj – Components are reassembled using OEM torque specifications. Clearance tolerances on the cylinder block / valve plate interface are verified.

5. Hidrolik test standında doğrulama – 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. Son kalite kontrol ve paketleme – The pump is painted, fitted with port protection caps, and packed in a heavy‑duty wooden case.

Yeniden üretilmiş pompamız neden daha ucuz “yenilenmiş” ünitelerden daha iyi performans gösterir:

• Yeni rulmanlar ve contalar – Many budget rebuilders reuse old bearings. We do not. All rotating components get new bearings.

• Hassas taşlanmış aşınma yüzeyleri – 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.

Satın almadığınız şey: 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+ yıllık sektör deneyimi – 2001 yılında kurulan şirketimiz, Hitachi, Caterpillar, Komatsu, Kobelco, Volvo, SANY ve diğer birçok marka için binlerce pompayı yeniden üretmiştir.

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

• 24 saat içinde sevkiyat – Guangzhou merkezimizden forwarder'ınıza 1 günde; uluslararası siparişler 24 saat içinde gönderilir.

• Pre‑shipment visual verification – Bir pompayı asla körlemesine göndermeyiz. Paketlemeden önce fiili ünitenin net fotoğraflarını alırsınız – siz onaylarsınız, biz göndeririz.

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