What are the key performance advantages of this pump?
- Load-Sensing Energy Efficiency: The DFLR control system detects real-time load demand and adjusts output flow accordingly, eliminating unnecessary flow waste. Reduces energy consumption by 25-30% compared to non-load-sensing pumps, ideal for energy-saving heavy-duty equipment.
- High-Flow & High-Pressure Capacity: 140 cm³/rev displacement and 350 bar max pressure deliver sufficient power for large hydraulic systems (e.g., large excavators, concrete pumps).
- Stable Operation: Precision-machined alloy steel cylinder block, chrome-plated pistons, and optimized swashplate design ensure minimal pressure ripple (<5% at rated load) and long service life (≥ 10,000 operating hours under rated conditions).
- Integrated Safety Protection: Built-in pressure relief valve (set to 315 bar) prevents system overpressure damage; anti-cavitation design enhances reliability in low-inlet-pressure scenarios.
- Low Noise & Vibration: Hydraulic damping structure and optimized flow channels reduce noise to ≤ 82 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 outdoor mobile machinery and indoor industrial systems.
