Hydraulic Gear Pump for Doosan 150 & Hyundai 150 Wheel Excavator

Product Overview

This Hydraulic gear pump is the core power component of the hydraulic system for Doosan 150 and Hyundai 150 wheel excavator Machine. As a reliable aftermarket replacement hydraulic pump, it delivers pressurized hydraulic oil to support travel, steering, swing and auxiliary working actions of the wheel excavator. Built with heavy‑duty cast‑iron housing and precision‑machined gear set, this Hydraulic gear pump features stable flow output, low internal leakage and excellent shock resistance, which is well‑adapted to harsh construction‑site environments and keeps the whole hydraulic system running steadily.

Technical Specifications

- Applicable Equipment: Doosan 150 Wheel Excavator, Hyundai 150 Wheel Excavator

- Product Type: External meshing Hydraulic gear pump

- Housing Material: High‑strength cast iron

- Working Medium: ISO VG32‑VG68 mineral hydraulic oil

- Operating Temperature: -20℃ ~ +80℃

- Feature: Direct interchange with original OEM assembly, no modification required for installation

- Main Function: Supply hydraulic power for travel, steering and auxiliary circuits inside the hydraulic system

Working Principle

Driven by the engine, the internal gear pair of this hydraulic pump rotates. It draws hydraulic oil from the reservoir and converts mechanical rotation energy into hydraulic pressure energy. The pressurized oil is transported through pipelines to all actuators of the hydraulic system. This Hydraulic gear pump ensures stable oil supply to realize compound movements of the Machine. Optimized clearance design effectively limits internal leakage under frequent pressure fluctuations.

Core Advantages

1. Perfect dimensional matching for Doosan 150 and Hyundai 150 wheel excavators, high interchangeability for original hydraulic pump.

2. Precision‑ground gear pair, low operating noise and small pressure pulsation, guarantees stable performance of the hydraulic system.

3. Robust cast‑iron body, good vibration and impact resistance, suitable for long‑time heavy‑load operation of the Machine.

4. Strict manufacturing quality control, reduces premature failure risk of this Hydraulic gear pump in complex working conditions.

5. Cost‑effective aftermarket solution, lowers maintenance cost and reduces downtime for the whole hydraulic system.

Application Scope

This Hydraulic gear pump is specially designed for Doosan 150 and Hyundai 150 wheel excavator Machine. It is installed in the main power circuit of the hydraulic system, acting as the key hydraulic pump to drive travel, steering and auxiliary hydraulic functions. Widely used in municipal engineering, road maintenance and material handling scenarios.
