KYB Product Series PSVD2-13E Hydraulic Pump - Detailed Introduction
I. Product Overview
The KYB PSVD2-13E hydraulic pump is anaxial-piston variable displacement pumpspecifically designed for construction machinery (e.g., excavators, loaders). It features high efficiency, reliability, and durability, with variable displacement control to meet dynamic power demands across diverse operating conditions.
II. Key Specifications
1. Model: PSVD2-13E
2. Displacement: 13 mL/rev (some variants may indicate "13×2," representing a dual-pump configuration).
3. Pressure Ratings:
• Rated pressure: 20 MPa (some sources cite 25 MPa; refer to official documentation for accuracy).
• Peak pressure: 25 MPa (or higher, depending on application).
4. Speed Range: Typically 1,000–3,000 rpm (varies by equipment model).
5. Weight: Approximately 20–63 kg (subject to configuration).
6. Materials: Cast iron pump body with high-strength alloy steel for pistons and critical components, ensuring wear resistance and impact durability.
III. Technical Features
1. Variable Displacement Control:
• Supports hydraulic or mechanical control for real-time displacement adjustment, optimizing energy efficiency.
• Pressure compensation available in select models for load-sensitive control, enhancing system stability.
2. High-Efficiency Design:
• Axial-piston structure minimizes internal leakage, improving volumetric efficiency.
• Optimized piston-pair design reduces friction losses, extending service life.
3. Durability:
• Strong resistance to contamination, suitable for harsh environments (e.g., high temperatures, dust).
• Key components (e.g., chrome-plated pistons) enhance wear and corrosion resistance.
4. Compatibility:
• Replaces equivalent models from Hitachi, Komatsu (e.g., Hitachi HPV091, Komatsu HPV90), reducing maintenance costs.
• Supports multiple mounting interfaces (e.g., SAE flanges) for seamless integration into existing systems.
IV. Applications
1. Construction Machinery:
• Excavators (main pump, pilot pump).
• Loaders, cranes (power transmission systems).
2. Agricultural Machinery:
• Tractors, harvesters (hydraulic drive systems).
3. Industrial Equipment:
• Injection molding machines, die-casting machines (hydraulic power units).
4. Marine & Offshore Engineering:
• Winches, deck machinery (low-speed, high-torque requirements).
V. Market Feedback
1. Strengths:
• Cost-Effective: Competitively priced compared to original imported pumps while maintaining KYB’s quality standards.
• Reliable Supply: Stocked by multiple domestic distributors (e.g., Guangzhou Baiyuan, Shandong Feici) for fast delivery.
• Comprehensive Support: Technical assistance and spare parts availability minimize downtime.
2. Considerations:
• Verify model compatibility (e.g., displacement differences between PSVD2-13E and PSVD2-17E).
• Adhere strictly to torque specifications during installation to prevent leaks or damage.
• Regularly replace hydraulic oil and filters to maintain system cleanliness.
