Pompa Hidraulik Utama Hitachi EX200-3 – Rekondisi China (9133006)

Deskripsi

Informasi Detail

1. Fitur & Manfaat Utama

• Factory-spec remanufacturing for EX200-3 – This 9133006 main hydraulic pump 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, and 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 tandem axial piston design – The 9133006 is a variable displacement double (tandem) axial piston pump, combining two independent pumping sections in one housing. This design powers the travel, swing, boom, arm, and bucket circuits simultaneously, providing smooth, coordinated operation for your EX200‑3 (19‑ton class excavator).

• Restored hydraulic power for 20‑ton class work – After remanufacturing, this pump delivers rated working pressure up to 31.9 MPa (≈4,630 psi) and a total flow of approximately 2 × 200 L/min. Your EX200‑3 regains full digging force, fast cycle times, and responsive travel and swing.

• Sistem kontrol daya terintegrasi (load-sensing) – Pompa yang dibangun kembali mempertahankan sistem kontrol daya pabrik, yang menyesuaikan keluaran pompa dengan beban kerja aktual. Ini mengurangi konsumsi bahan bakar, mencegah mesin mati, dan memperpanjang umur pompa serta sistem hidrolik. Pompa roda gigi pilot integral juga dibangun kembali untuk memasok sirkuit kontrol.

• Alternatif hemat biaya untuk unit asli baru – A new genuine Hitachi main pump for a 20‑ton excavator is a significant investment. Our remanufactured 9133006 gives you the same fit, form, and function at a much lower price, without sacrificing reliability. Each pump is tested on a hydraulic test stand before dispatch.

• Pengganti baut langsung – 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.

• Verifikasi visual pra-pengiriman – Sebelum pengemasan, kami mengirimkan foto resolusi tinggi terperinci dari unit buatan ulang yang sebenarnya (flensa pemasangan, spline, ulir port, kondisi umum). Anda menyetujui pengiriman – kami tidak pernah mengirim secara buta.

• Pengiriman cepat – Waktu tunggu 5–8 hari kerja dari gudang Guangzhou kami. Kapasitas pasokan bulanan 300 unit, tersedia untuk pesanan satuan atau grosir.

2. Aplikasi

The remanufactured Hitachi 9133006 main pump is ideal for EX200‑3 and 20‑ton class excavators used in a wide range of demanding environments:

• Konstruksi berat & infrastruktur – Highway excavation, dam building, bridge footings, and large‑scale earthmoving. The restored tandem pump delivers simultaneous boom, arm, and travel power without internal leakage – no power fade, no sluggish response.

• Penambangan & agregat – Loading trucks, stockpile management, and material handling in abrasive dust conditions. New bearings and seals ensure the pump survives where worn units fail.

• Dukungan pertambangan – Site cleanup, road maintenance, drainage works. The pump’s load‑sensing control reduces fuel consumption during light‑duty cycles.

• Pembongkaran & pemrosesan besi tua – Shock loads and vibration are routine. Our remanufacturing process replaces all wear components, restoring the pump‘s ability to withstand harsh conditions.

• Armada sewa peralatan – 20‑ton excavators are rental workhorses. 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.

• Kehutanan & pembukaan lahan – Steep slopes, fallen timber, hidden obstacles. The integral power control prevents engine stall under sudden load spikes.

3. Maintenance Tips – Extend the Life of Your Remanufactured Pump

A properly installed and maintained pump can deliver years of reliable service. Follow these tips to protect your investment:

• Replace hydraulic filters on schedule – Contaminated oil is the #1 killer of hydraulic pumps. Use genuine or high‑quality filters and change them at Hitachi‑recommended intervals (typically 500–1,000 hours). A clogged or bypassing filter allows debris to score the cylinder block and valve plate.

• Keep oil clean and at the correct viscosity – Use ISO VG 46 for normal temperatures, ISO VG 68 for hot climates or continuous heavy duty. Water contamination degrades oil and causes internal rust. Have your oil analysed annually.

• Warm up the pump before heavy work – Run the engine at low idle for 3–5 minutes, then cycle all hydraulic functions slowly without load. This allows oil to reach all internal components and prevents cavitation damage.

• Monitor case drain flow – Excessive case drain leakage (more than 15–20 L/min) indicates internal wear. Measure it every 1,000 hours. A sudden increase signals impending failure.

• Dengarkan suara yang tidak biasa – Knocking, whining, or squealing from the pump area often indicates cavitation (starved suction), worn bearings, or loose mounting. Investigate immediately – continued operation will cause catastrophic failure.

• Check pump alignment – Misalignment between the pump and engine flywheel housing puts side load on the shaft, destroying bearings and the shaft seal. After any engine or pump removal, verify alignment with a dial indicator.

• Keep the case drain line clear – A kinked or blocked case drain line will cause back pressure inside the pump housing, blowing the shaft seal. Inspect the line whenever you service the pump.

• Store spare pumps properly – Keep remanufactured pumps in their original wooden case, in a dry, clean environment. Rotate the shaft by hand every 6 months to redistribute internal lubricant.

• Use new O‑rings and sealing washers – When installing a remanufactured pump, always replace all seals on hydraulic connections. Reused seals are the most common source of external leaks.

• Bleed air after installation – After fitting the pump, run the engine at low idle and slowly cycle each function several times to purge trapped air. Air in the system causes cavitation and noisy operation.

• Keep a service log – Record installation date, hours, oil changes, and any unusual observations. This helps you anticipate pump life and avoid unexpected downtime.

Critical installation tip for the 9133006 remanufactured pump:
– saluran case drain must be unrestricted. A blocked drain will blow the shaft seal instantly on first startup.
– Before installing the remanufactured pump, flush the entire hydraulic system and replace all filters. Contaminants from the failed pump will destroy a remanufactured unit just as quickly as a new one.
– Use new O‑rings and sealing washers on every hydraulic connection.
– After installation, idle for 2–3 minutes, then slowly cycle each function to purge air.
– Check pump alignment with the engine flywheel housing – misalignment causes premature bearing failure.
