3. What are the key performance advantages of this pump?
- Precise Dual Control: Hydraulic pilot pressure-flow compensation (DFR1) enables stepless flow adjustment (0-100%) based on system load, reducing energy waste and improving operational efficiency.
- High Pressure Resistance: Robust cylinder block and piston design (alloy steel material) ensures stable performance at 350 bar max pressure, with volumetric efficiency ≥ 95% and mechanical efficiency ≥ 92%.
- Reliable Protection: Integrated pressure relief valve (VSC62) prevents overpressure damage, adjustable within 100-350 bar; anti-cavitation and anti-shock design enhances durability in harsh working conditions.
- Low Vibration & Noise: Optimized swashplate design and hydraulic damping structure reduce noise to ≤ 80 dB(A) at rated speed, improving operator comfort.
- Wide Operating Range: Adapts to extreme temperatures (-20°C to +90°C) and variable viscosity oils, suitable for both mobile and industrial applications.
- Easy Integration: Standardized mounting dimensions and port sizes ensure compatibility with existing hydraulic systems, facilitating retrofitting and replacement.
