Description
K5V200DPH 4633472 Hydraulic Pump Assembly Overview
The K5V200DPH 4633472 Hydraulic Pump Assembly manufactured by Tatan is a heavy-duty tandem variable displacement axial piston pump belonging to our Hydraulic Pump Assembly classification. Engineered specifically for Hitachi ZX470-5G, ZX470LC-5G, ZX470H, and ZX490-5A 47-49 ton heavy mining excavators, swapping to a complete K5V200DPH 4633472 Hydraulic Pump Assembly restores sluggish compound movements, eliminates hydraulic oil overheating, and stops Isuzu 6WG1-T engine bogging under high-pressure quarry rock trenching.
Constructed with dual 200 cc/rev rotating groups, hardened bi-metal valve plates, and factory-calibrated negative flow control (NFC) regulators, this complete unit ensures balanced flow division across dual hydraulic circuits and delivers 100% direct mechanical alignment with the 15.7L diesel engine flywheel coupling.

Application Scenarios & Buyer Value
When resolving hydraulic pressure drop and sluggish movement with our K5V200DPH 4633472 Hydraulic Pump Assembly, workshops and equipment contractors eliminate repetitive downtime:
| Application Scenario | Value Delivered to Buyer |
|---|---|
| Hitachi ZX470 Field Pump Swap | Installing the K5V200DPH 4633472 Hydraulic Pump Assembly cuts equipment overhaul downtime by up to 75% compared to trial-and-error field rebuilding. |
| Hydraulic Service Workshops | Avoids the high failure risk of reusing warped swashplate cradles or scored cylinder barrel casings that cause internal bypass under 47-ton rock loads. |
| Quarry & Heavy Earthmoving Fleets | Restores rapid simultaneous boom raising, bucket crowding, and swing rotation without 6WG1 engine stalling under heavy 2.5 m³ trenching loads. |
| Global Heavy Machinery Stockists | Fully bench-tested, export-crated heavy inventory ready for prompt international air express or container shipment. |
K5V200DPH 4633472 Hydraulic Pump Assembly OEM Diagnostic Guide
Use this technical diagnostic guide to identify hydraulic pump faults on your Hitachi ZX470 excavator:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Digging speed slows down dramatically when oil heats up | Severe internal oil leakage across scored valve plates and worn piston shoes, dropping flow output and system pressure below 26.0 MPa. | Replace with a complete K5V200DPH 4633472 Hydraulic Pump Assembly. |
| 2. Isuzu 6WG1-T engine bogs down or stalls when curling the bucket | Negative flow control (NFC) regulator spool stuck in maximum swashplate angle position, overloading the 15.7L engine under relief pressure. | Inspect regulator pilot pressure signal (3.9 MPa) or swap to a pre-calibrated factory pump assembly. |
| 3. Loud whining noise & pump body pulsation under load | Pump cavitation caused by restricted suction strainer, aerated hydraulic oil, or damaged suction manifold O-ring seals. | Clean suction line, replace hydraulic return filters, bleed pump casing air, and check pump priming before restart. |
| 4. External oil leak from the pump front drive seal | High case-drain backpressure exceeding 0.25 MPa due to clogged case-drain filters, blowing out the front drive shaft oil seal. | Clear case-drain line restrictions, replace case filters, and install a brand new sealed pump assembly. |
