Hitachi ZX470‑3 Hydraulic Main Pump | 4633472 K5V200DPH‑OE02 Axial Piston Pump | Excavator Aftermarket Replacement Parts

Product Brief

This K5V200DPH‑OE02 double‑variable axial piston main pump, part number 4633472, serves as the core hydraulic power source for heavy‑duty Hitachi ZX470‑3 excavator. Engineered for large‑tonnage mining and earth‑moving scenarios, it converts engine power into high‑pressure hydraulic output to support heavy digging, rock breaking, slope trimming and long‑hour continuous site operation. This aftermarket pump is widely adopted by mining contractors, equipment repair workshops and cross‑border spare‑part dealers across Africa, Middle East and Central Asia for overhaul and unit replacement.

Working under frequent heavy‑load impact and high‑temperature operating conditions, large‑size main pumps tend to suffer cylinder block scuffing, piston shoe wear, valve plate damage and internal leakage. Typical failure symptoms include insufficient breakout force, sluggish combined actions, sharp rise of hydraulic oil temperature, harsh metallic noise from pump housing and obvious power loss. Sudden pump breakdown on mining sites will trigger long‑term equipment downtime and bring huge economic loss to project owners.

Our aftermarket main pump strictly follows OEM standards for mounting flange dimension, spline tooth count, solenoid valve interface and pressure setting. No extra machining or modification is needed for field swap, supporting direct installation to shorten machine idle period. As a cost‑competitive alternative to high‑priced original assemblies with long lead‑time, this pump maintains stable output performance under factory wholesale price, perfectly matching bulk procurement demand for heavy machinery spare‑part suppliers.

Unique Product Competitive Advantages

1. Strictly matched for ZX470‑3 electronic‑controlled hydraulic system, non‑universal for other heavy excavator models
Manufactured according to original installation drawing, this main pump keeps consistent solenoid installation position, oil port layout and pressure calibration. Well‑matched friction pairs effectively reduce inner leakage after assembly. No adapter block or cutting work required during replacement.
2. Reinforced friction pair components to extend service life under mining heavy‑load conditions
Many low‑cost substitute pumps fail quickly under rock‑digging working conditions because of inferior friction‑pair raw materials. Our core internal components adopt standardized heat‑treatment and fine‑grinding craft, improving anti‑wear performance under sharp load fluctuation. It helps fleet owners cut down pump replacement frequency for heavy‑usage machines.
3. Full‑set bench testing before shipment to eliminate hidden failure risks
Every finished hydraulic pump passes pressure endurance test, flow detection and leakage inspection on professional hydraulic test bench before packing. Defective goods are screened out in factory, avoiding re‑work trouble for maintenance teams and unexpected shutdown loss on construction or mining sites.
4. Economic aftermarket solution to control heavy‑equipment operating expenditure
Genuine OEM main pumps for 47‑ton excavators come with high cost and long delivery cycle. Our aftermarket pump realizes comparable working performance at factory direct price, effectively lowering overall maintenance cost for enterprises running multiple large excavator units.
5. Diversified logistics schemes for wholesale clients
In‑stock items can be dispatched quickly upon payment confirmation. Air freight is available for urgent breakdown repair orders; consolidated sea freight and full‑container service provide cost‑saving choices for long‑term bulk purchasers.

Factory Production Strength

Our manufacturing base concentrates on researching and producing aftermarket hydraulic main pumps, travel motors and swing motors for various heavy‑duty excavator brands. We possess complete production procedures including alloy steel forging, precision grinding, heat‑treatment processing and finished‑product hydraulic bench test. Professional simulation test equipment reproduces real‑world mining heavy‑load working status to continuously optimize component stability and wear resistance. Our hydraulic assemblies are exported to multiple overseas regions and maintain stable long‑term cooperation with global construction machinery spare‑part wholesalers.

Frequently Asked Customer Questions

Q1: Can this 4633472 K5V200DPH‑OE02 main pump fit other excavator models besides Hitachi ZX470‑3?
A1: Cross‑model installation is not supported. Different heavy excavator models adopt main pumps with different flange sizes, solenoid parameters and pressure setup. Please double‑check machine model and OEM part number before placing orders.

Q2: What typical hydraulic malfunctions can this pump resolve?
A2: It fixes faults caused by worn pistons, scratched valve plate and damaged internal components: weak digging force, slow compound movements, high hydraulic oil temperature, internal leakage and abnormal knocking noise of main pump.

Q3: Can you offer preferential price for bulk‑quantity orders?
A3: Yes, tier‑based discount is available according to purchase quantity. We can also arrange full‑container sea shipment to reduce comprehensive logistics cost.

Q4: What packaging is adopted for long‑distance ocean transportation?
A4: Anti‑rust oil is coated on all metal surfaces. The whole pump is wrapped by waterproof shock‑proof PE film, then fixed inside reinforced export‑grade plywood case, to prevent collision deformation and moisture corrosion during long overseas transit.
