Product details

I. Product Overview

These models belong to theHZCAT series medium-pressure swashplate axial piston pumps, featuring:

• Operating Pressure: 280 bar

• Speed Range: 1,500–1,800 rpm

• Displacement: 100 ml/r

• Control Modes: Supports constant pressure (DR), constant flow (DFR), constant power (DFR1/DFLR), and remote pressure regulation (DRG).

• Structural Advantages: Compact design, lightweight (pump weight ~55 kg), low noise, and long service life.

• Combination Applications: Can be integrated into tandem pump systems for complex hydraulic requirements.

------

III. Applications

1. Construction Machinery

• Excavators: Compatible with Caterpillar 365B, 345B, 330D series.

• Loaders: Used in articulated loaders and off-road trucks (e.g., 777D, 797 models).

• Bulldozers: Provides high-pressure hydraulic power for heavy-duty operations.

2. Agricultural Machinery

• Tractors and combine harvesters for precise control of plowing and harvesting.

3. Industrial Machinery

• Metallurgical equipment, mining machinery, and shipbuilding applications.

------

IV. Key Advantages

1. Energy Efficiency

• Variable displacement control (e.g., load-sensing) automatically adjusts flow to reduce energy waste and operating costs.

2. High Reliability

• Built with high-strength materials (e.g., cast iron cylinder blocks, hardened alloy pistons) for durability in harsh conditions (service life > 20,000 hours).

3. Easy Maintenance

• Modular design allows quick replacement of critical components (e.g., piston pairs, port plates).

4. Compatibility

• Replaces parts from Caterpillar, Rexroth (e.g., 112-6564, 235-4110), reducing procurement costs.
