Product details

I. Product Overview

These models (e.g.,224-6369, 161-6634) typically belong tohigh-pressure axial piston pumps, designed for mobile hydraulic systems in construction machinery, agricultural equipment, forestry machinery, and more. Their core function is to pressurize hydraulic fluid through the reciprocating motion of pistons, providing power to the system.

II. Typical Applications

1. Construction Machinery

• Bulldozers, loaders, excavators, road rollers, etc., for driving hydraulic cylinders or motors to perform digging, lifting, steering, and other functions.

2. Agricultural Machinery

• Tractors, combine harvesters, providing hydraulic power for plowing, harvesting, and other operations.

3. Forestry Machinery

• Logging skidders, timber forwarders, for tree cutting, handling, and transportation.

4. Material Handling Equipment

• Forklifts, container reach stackers, for lifting and moving goods.

------

III. Technical Features

1. High-Pressure Design

• Rated pressure typically reaches320–350 bar, with peak pressure exceeding400 bar, meeting heavy-duty requirements.

2. Variable Displacement Control

• Supportsload-sensing (LS), pressure-compensated (DR)control, automatically adjusting displacement based on load demand for improved energy efficiency.

3. Compact Structure

• Axial piston design ensures a small footprint and lightweight construction, facilitating installation in confined spaces.

4. High Reliability

• Built with high-strength materials (e.g., cast iron cylinder blocks, hardened alloy pistons) to withstand harsh conditions and ensure long service life.
