Product details
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).
