Product details
HPV118JW Hydraulic Pump For ZX200-5G/ZX240-5G
1. Product Overview
HPV118JW is a swashplate tandem variable axial piston pump, acting as the core hydraulic power assembly for Hitachi ZX200-5G and ZX240-5G medium crawler excavators.
Adopting integrated dual-pump layout equipped with negative flow control regulators and built-in pilot gear pump. It provides high-pressure hydraulic oil to drive boom, arm, bucket, slewing and travelling hydraulic actuators of excavator. High-quality interchange aftermarket pump assembly can directly replace OEM pump for equipment overhaul and maintenance.

3. Working Principle
The engine drives main shaft and cylinder block to rotate synchronously. The reciprocating movement of pistons forms continuous oil suction and high-pressure discharge circulation.
The negative flow regulator automatically adjusts swashplate tilt angle according to feedback signal pressure from main control valve, changes pump displacement and adjusts output flow to match real-time load demand. Optimized power matching reduces overflow loss, lowers fuel consumption and stabilizes hydraulic oil temperature.
The whole hydraulic system realizes composite actions including excavation, lifting, travelling and slewing of medium excavator.
4. Core Advantages
1. Specially calibrated for Hitachi ZX200-5G / ZX240-5G; mounting flange, spline shaft and oil port layout fully consistent with original pump, supporting direct plug-and-play replacement.
2. Precisely machined internal friction pairs, low internal leakage, maintaining stable volumetric efficiency under long-term continuous heavy-load operation.
3. Upgraded negative flow control system, excellent power matching with engine, effectively reducing system heat generation and fuel consumption.
4. High-rigidity cast pump housing, outstanding shock and vibration resistance, suitable for earthwork, municipal construction, road engineering and pipeline laying.
5. Stable flow output, small flow pulsation, smooth compound movement and comfortable operating feeling.
6. Reliable aftermarket replacement assembly with shorter delivery lead time compared with original genuine hydraulic pump.
5. Application Range
Main hydraulic pump for Hitachi medium crawler excavator:
Hitachi ZX200-5G, ZX240-5G
Widely used in earthmoving works, municipal engineering, highway construction, landscaping and general infrastructure projects.
6. Common Faults & Replacement Suggestion
Typical failures: Insufficient digging force, slow composite movements, excessive hydraulic oil temperature, abnormal knocking noise, shaft seal leakage.
Thoroughly flush all hydraulic pipelines and replace all hydraulic filter elements before installation. Strictly ensure hydraulic oil cleanliness to prevent impurities from scratching cylinder block, piston shoes and valve plate. Replace complete pump assembly if serious internal abrasion occurs.
