What are the key performance advantages of these pumps?
- Precise Dual Control: Hydraulic pilot pressure-flow compensation (DFR1) enables stepless displacement adjustment (0-100%), matching flow output to system load and reducing energy consumption by 20-25% compared to fixed-displacement pumps.
- High-Pressure Durability: Reinforced alloy steel cylinder block, precision-ground valve plate, and chrome-plated piston assembly withstand 350 bar max pressure, ensuring stable operation for ≥ 10,000 operating hours in heavy-duty scenarios.
- Integrated Safety Protection: Built-in pressure relief valve (set to 350 bar) prevents system overpressure damage; anti-cavitation design enhances reliability in low-inlet-pressure conditions (e.g., long-distance oil supply).
- Low Noise & Vibration: Optimized swashplate profile and hydraulic damping structure reduce noise to ≤ 80 dB(A) at rated speed, meeting industrial noise standards and improving operator comfort.
- Wide Adaptability: Operates reliably in extreme temperatures (-20°C to +90°C) and variable oil viscosities, suitable for both indoor industrial equipment (e.g., injection molding machines) and outdoor mobile machinery (e.g., excavators).
- Easy Integration: Standardized mounting dimensions and port sizes ensure compatibility with existing hydraulic systems, supporting seamless retrofitting and replacement.
