It is worth choosing a product that features stable performance, high reliability, easy installation, and quick response.

1. Key Features & Benefits

• Factory-spec remanufactured main pump – This YB6000054 hydraulic pump has been completely disassembled, cleaned, crack-inspected, and rebuilt in our ISO-certified facility. All wear components – cylinder block, piston assemblies, valve plate, swashplate, bearings, and seals – are replaced with new, high-quality parts. The result is performance and reliability comparable to a new unit at a fraction of the cost.

• Designed for ZAX200-5B and compatible 20‑ton class excavators – This pump is engineered for Hitachi ZAX200-5B, ZX200-5B, ZX200-5G, and related 20‑ton class models. It powers the boom, arm, bucket, swing, and travel circuits with smooth, responsive hydraulic flow.

• Restored 20‑ton class hydraulic power – The ZAX200-5B has an operating weight of approximately 21,200 kg and is powered by a 109 kW engine. After remanufacturing, this pump delivers the full rated flow and pressure – your excavator regains original digging force, fast cycle times, and precise attachment control.

• Tandem variable displacement axial piston design – Two independent pumping sections in one housing allow simultaneous operation of multiple functions (e.g., travelling while booming up) without internal flow loss – no power fade, no sluggish response.

• Integrated load‑sensing power control – The factory control system is fully rebuilt and calibrated. 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.

• New bearings and precision‑ground wear surfaces – All bearings are replaced – never reused. The cylinder block and valve plate are re‑ground to restore flatness, ensuring minimal internal leakage, cooler oil, and better efficiency.

• Direct bolt‑on replacement – Mounting flange, drive shaft spline, and hydraulic port configurations are restored to original Hitachi specifications. No modifications, no adapters – your mechanic unbolts the old pump and bolts this one in.

• Hydraulic test stand validated – Each remanufactured pump is run on a test stand to verify rated pressure, flow, case drain leakage, and control response. A test report is available upon request.

• Pre‑shipment visual verification – We send you clear, high‑resolution photographs of the actual pump (mounting flange, splines, port threads, castings) before packing. You approve – we ship. Never blind.

• Fast delivery – 5–8 working days from our Guangzhou warehouse. Monthly capacity 300 units.

2. Applications

The remanufactured Hitachi ZAX200‑5B main pump is ideal for 20‑ton class excavators used across a range of demanding job sites:

• Heavy construction & infrastructure – 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, even on long shifts.

• Quarrying & aggregates – Loading trucks, stockpile management, and material handling in abrasive dust conditions. New bearings, seals, and wear plates ensure the pump survives 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.

• Demolition & scrap processing – Shock loads and vibration are routine in demolition yards and metal recycling facilities. Our remanufacturing process replaces all wear components, restoring the pump‘s ability to withstand harsh, unpredictable conditions.

• Equipment rental fleet – 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, towing bills, and customer complaints.

• Forestry & land clearing – 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 Hongtengda Parts – Remanufacturing That Actually Works

Many hydraulic shops offer “rebuilt” pumps. They disassemble, replace O‑rings, add new paint, and call it done. The cylinder block remains scored. The valve plate remains warped. The bearings remain fatigue‑cracked. Within 500–1,000 hours, internal leakage returns, oil temperature climbs, and you lose power again.

Our remanufacturing is different. We replace what is worn, not just what leaks.

Our 6‑step process:

1. Complete disassembly – Pump stripped to every component: cylinder block, pistons, valve plate, swashplate, bearings, shaft, housing, control valves.

2. Cleaning & crack inspection – All parts cleaned, critical castings dye‑penetrant inspected. Irreparable parts scrapped.

3. Wear component replacement – All seals, O‑rings, bearings, gaskets replaced. Cylinder block and valve plate re‑ground to original flatness. Piston assemblies replaced as matched set if worn. Swashplate reconditioned.

4. Precision reassembly – Assembled using OEM torque specs. Clearance tolerances verified.

5. Hydraulic test stand validation – Tested for rated pressure, flow, case drain leakage, and load‑sensing response. Test report available.

6. Final quality check & packaging – Painted, port caps fitted, packed in heavy‑duty wooden case.

What you are buying: A pump with new bearings, new seals, ground wear surfaces – restored to OEM performance. Not a band‑aid.

What you are not buying: A used pump with fresh paint and a set of O‑rings.

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

Critical installation tip for the YB6000054 remanufactured pump:
– Case drain line must be unrestricted. Blow compressed air through it before connecting. A blocked drain will blow the shaft seal instantly on first start.
– 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. Reused seals guarantee leaks.
– After installation, run the engine at low idle for 2–3 minutes with the pump 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.

Warranty note: Warranty period is 3 to 6 months depending on product details. We do not provide warranty service for original used or remanufactured parts. Our value is delivered up front: careful remanufacturing, thorough testing, and pre‑shipment visual verification. For customers who require a warranty‑covered option, we can quote new aftermarket units – ask our sales team.
