II. Technical Features

1. Variable Displacement Technology

• Adjusts vane angles to regulate flow, achieving amaximum flow rate of 40 L/min (at 1,800 RPM)to meet dynamic hydraulic system requirements.

• Energy efficiency improved by over 20%compared to fixed-displacement pumps, minimizing energy waste.

2. High-Pressure & High-Efficiency Output

• Maximum operating pressure: 70 kgf/cm² (7 MPa), suitable for high-load applications.

• Hydraulic fluid compatibility: Designed for fluids with a viscosity range of32–55 cst (at 38°C), adapting to diverse operating conditions.

3. Robust Construction & Materials

• Pump body: Cast iron with anti-corrosion treatment, ideal for harsh industrial environments.

• Vanes: Precision-machined for optimal fit with the pump chamber, reducing wear and extending service life.

4. Low Noise & Stability

• Operates quietly with minimal vibration, reducing stress on mechanical couplings and seals.

• Balanced design ensures stable long-term performance, ideal for continuous-duty equipment.
