Product details

I. Product Positioning & Core Specifications

TheK3V63~280belongs to Kawasaki'sK3V Seriesof hydraulic axial piston pumps, designed for high-load industrial and mobile hydraulic systems. Key parameters include:

• Displacement Range: 63 mL/rev (some models support dual-pump configurations, e.g., K3V63DT with dual 63 mL/rev for a total of 126 mL/rev).

• Rated Pressure: 34.3 MPa (peak pressure up to 40 MPa for select models).

• Rated Speed: 2,200 rpm (maximum speed varies by model).

• Maximum Flow Rate: ~138.6 L/min for single-pump configurations (double for dual-pump setups).

• Power Compatibility: Suitable for power systems below 70 kW, with a torque capacity of 304 N·m.

II. Technical Features & Advantages

1. Dual-Ring Axial Piston Design

• Optimized pressure distribution reduces internal leakage and enhances volumetric efficiency, ideal for heavy-duty continuous operation.

2. Variable & Fixed Displacement Configurations

• Variable Pumps (e.g., K3V63RDP): Adjust swashplate angle for stepless flow control, enabling load-sensing systems to reduce energy consumption.

• Fixed Displacement Pumps (e.g., K3V63SRB): Simplified structure with stable output for fixed-load applications (e.g., die-casting machines, injection molding).

3. High Pressure & Durability

• Rated pressure of 34.3 MPa (peak 40 MPa) meets demands of excavators, cranes, and other high-pressure equipment.

• Reinforced swashplate and precision piston seals extend service life.

4. Compact & Lightweight

• Axial piston structure minimizes space requirements, facilitating integration into compact machinery (e.g., mini-excavators, agricultural equipment).

5. Easy Maintenance

• Modular design allows quick disassembly of critical components (e.g., bearings, seals) for on-site repairs, reducing downtime.

III. Typical Applications

1. Construction Machinery

• Excavators: Primary pump for driving travel, slewing, and attachment movements (boom, arm, bucket).

• Cranes: Provides hydraulic power for boom extension, slewing, and luffing.

• Loaders: Powers working attachments (bucket lift/tilt) and steering systems.

2. Industrial Equipment

• Die-Casting Machines: Delivers high-pressure hydraulic power for mold opening/closing and product ejection.

• Injection Molding Machines: Drives screw rotation and mold movement for stable injection processes.

• Marine Equipment: Used in steering gear and anchor winches for marine applications.

3. Agricultural Machinery

• Combine Harvesters: Powers header lift and threshing drum operations.

• Tractors: Provides hydraulic suspension power for implement lifting.
