Hengli Main Hydraulic Pump for LiuGong 920E / 922E, XCMG 200 / 215

Product Overview

This Hengli main hydraulic pump is a high-performance axial piston hydraulic pump specially designed for LiuGong 920E, 922E and XCMG 200, XCMG 215 excavators. As the core power component of the hydraulic system, it converts mechanical energy into hydraulic power to drive all machine actions including boom, arm, bucket and slewing movement. Adopting mature electro-hydraulic control structure, it delivers stable output flow and pressure, perfectly matching the working demands of 20-ton class excavators.

Technical Specifications

- Brand: Hengli

- Applicable Models: LiuGong 920E, 922E; XCMG 200, XCMG 215 Excavator

- Type: Axial Piston Main Hydraulic Pump

- Control Mode: Electro-hydraulic control

- Suitable Machine: 20 ton excavator

- Features: High pressure resistance, low noise, reliable continuous operation, easy maintenance

Working Principle

The engine drives the rotating cylinder block inside the hydraulic pump. By changing the swash plate angle, the displacement is adjusted dynamically. It outputs pressurized hydraulic oil to the whole hydraulic system, providing power for multiple actuators on the machine. The electro-hydraulic control system can intelligently adjust flow according to load changes to reduce energy consumption and improve working efficiency.

Core Advantages

1. Original Hengli quality, precise fit for LiuGong and XCMG 20-ton excavators, direct replacement without modification.

2. Strong anti-shock performance, stable pressure output under heavy load working conditions.

3. Low vibration and low noise, extending service life of the whole hydraulic system.

4. Simple structure, convenient inspection and replacement of wearing parts, lower maintenance cost.

5. Strict factory testing, stable performance for long-time continuous construction work.

Application Range

Widely used in 20-ton construction machine, including LiuGong 920E,922E and XCMG 200,215 excavators. Suitable for earthmoving, quarrying, road construction and other heavy-duty working scenarios.
