TheK3VL28/C-10RSM-PR-T459 hydraulic piston pumpis a high-performance, variable-displacement axial piston pump designed for heavy-duty industrial and construction machinery applications. Below is a detailed overview of its specifications, features, and applications:
Key Technical Specifications
1. Model & Series:
• Model: K3VL28/C-10RSM-PR-T459
• Series: K3VL (Kawasaki's axial piston pump series for medium-displacement applications).
2. Displacement:
• Typically available in45 cc/rev(adjustable based on configuration).
3. Pressure Ratings:
• Maximum Operating Pressure: 35 MPa (350 bar).
• Peak Pressure: Up to 40 MPa (400 bar) for short-term operation.
4. Speed Range:
• Nominal Speed: 1,800–2,200 rpm.
• Maximum Speed: 2,500 rpm (short-term).
5. Control Options:
• Electro-hydraulic proportional control(for precise flow/pressure regulation).
• Pressure compensation(to maintain consistent performance under varying loads).
• Manual override(for emergency or maintenance purposes).
6. Mounting & Porting:
• Shaft Orientation: SAE standard (flange or keyed shaft).
• Port Configuration: SAE flange ports (e.g., SAE 6B or SAE 8B).
7. Weight & Dimensions:
• Weight: ~35–48 kg (depending on configuration).
• Dimensions: Compact design for integration into tight spaces.
8. Fluid Compatibility:
• Hydraulic Oil: ISO VG 46 or 68 (temperature range: -20°C to +80°C).
Features & Benefits
• High Efficiency:
• Axial piston design ensures high volumetric and mechanical efficiency (>92%).
• Durability:
• Hardened chrome-plated pistons and high-strength cylinder blocks resist wear and corrosion.
• Low Noise:
• Optimized flow path and reduced internal leakage minimize noise levels (<85 dB(A)).
• Energy Savings:
• Variable displacement allows for power-on-demand operation, reducing energy consumption.
• Reliability:
• Tested to meet or exceed ISO 10770 and ISO 4409 standards for hydraulic pumps.
Applications
• Construction Machinery:
• Excavators (e.g., SANY SY485): Drives cooling fans, swing motors, and hydraulic attachments.
• Loaders & Bulldozers: Powers steering systems and hydraulic cylinders.
• Mining Equipment:
• Drilling Rigs & Haul Trucks: Provides hydraulic power for high-pressure applications.
• Agricultural Machinery:
• Combine Harvesters & Tractors: Operates hydraulic implements and steering systems.
• Industrial Machinery:
• Presses, Injection Molding Machines, & Material Handling Systems: Delivers precise flow and pressure control.
Compatibility with SANY SY485 Excavator
• Direct Replacement:
• The K3VL28/C-10RSM-PR-T459 is a drop-in replacement for the original Kawasaki fan pump in SANY SY485 excavators.
• Performance Upgrade:
• Improved efficiency and reliability compared to older models (e.g., K3VL28/C-9RSM-PR).
