2. 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.

3. Which applications is this pump designed for?

• Construction machinery (large excavators, wheel loaders, hydraulic cranes, concrete pumps)
• Mining equipment (underground haulers, rock drills, crushing machines)
• Industrial machinery (hydraulic presses, plastic injection molding machines, steel mills, paper machines)
• Agricultural machinery (large tractors, combine harvesters, irrigation systems)
• Marine systems (ship deck machinery, winches, steering gear)
• Offshore equipment (oil drilling rigs, platform hydraulic systems)

4. What are the installation and maintenance requirements?

• Installation:
  • Ensure concentricity between pump and motor ≤ 0.1 mm; use flexible coupling to absorb vibration.
  • Mount on a rigid base with shock-absorbing pads; reserve ≥ 15 cm clearance for heat dissipation and maintenance.
  • Prime the pump before initial startup to avoid dry running; ensure inlet oil pressure ≥ 0.8 bar.
