description

The PVK-2B-505 variable piston pump adopts an upgraded heavy-load reinforced swash plate variable structure, specially optimized and calibrated for the high-intensity heavy-duty cyclic operation of 5–6 ton medium excavators. It supports a rated working pressure of 270bar and a peak working pressure of 320bar, with comprehensively upgraded pressure resistance, impact resistance and load stability compared with PVD-2B-36 conventional heavy-duty micro pumps, fully adapting to rock excavation, hard soil cutting and long-term full-load continuous construction. The thickened high-density cylinder block, large-size precision piston assembly and super-finished valve plate are forged from high-strength wear-resistant alloy materials, matched with micro-gap dynamic self-compensation and anti-fatigue lubrication technology. It maintains volumetric efficiency ≥97% and mechanical efficiency ≥93% under long-term high-load operation, with extremely low performance attenuation. Equipped with a high-precision load-sensing variable control system, it dynamically adjusts flow and pressure according to real-time load changes, realizing sensitive action response, coordinated compound operation and stable heavy-load output.

advantages

  • 270bar High Standard Pressure Grade, Strong Impact Resistance: Upgraded 270bar rated pressure and 320bar peak pressure, higher than conventional micro and small excavator pumps. It stably resists instantaneous hydraulic impact and long-term overload holding pressure, ensuring stable operation in harsh rocky and earth-stone mixed working conditions.
  • Precision Load-Sensing Matching, Smoother Compound Actions: High-precision pressure feedback variable system realizes real-time dynamic power matching. It reduces invalid energy consumption under light load and rapidly boosts flow and pressure under heavy load, making lifting, slewing and digging compound actions more coordinated and fluent.
  • Enhanced Forced Heat Dissipation, No High-Temperature Power Decay: The upgraded large-flow heat dissipation structure quickly dissipates internal heat generated by high-intensity operation. It effectively avoids high-temperature speed drop, flow attenuation and oil aging failures during long-hour continuous heavy-load construction, ensuring stable all-weather operation.
  • High-Rigidity Anti-Fatigue Structure, Ultra-Long Service Life: Thickened core wear-resistant components and integral high-rigidity pump housing resist high-frequency vibration and fatigue damage caused by heavy-load impact. The optimized internal friction pair matching reduces wear loss, maintaining long-term high-efficiency and stable output.

FAQ

  • Q1: What excavators does the PVK-2B-505 fit for?
  • A: The PVK-2B-505 hydraulic pump is specially designed for 5–6 ton medium compact excavators, compatible with multiple mainstream domestic and imported medium excavator models. It is the standard high-power large-displacement main pump for 5–6 ton excavator hydraulic systems.
  • Q2: What is the difference between PVK-2B-505 and PVD-2B-36?
  • A: PVD-2B-36 is a 36ml/r heavy-duty pump for 3–4 ton micro excavators; PVK-2B-505 adopts upgraded 50ml/r large displacement and higher pressure grade, with stronger rock excavation and continuous high-load operation capacity, specially used for 5–6 ton medium excavator high-intensity construction.
  • Q3: What working conditions is PVK-2B-505 suitable for?
  • A: It is ideal for high-intensity heavy-load scenarios including hard soil cutting, rock excavation, deep foundation trenching, long-term full-load continuous operation and frequent earth-stone mixed construction of 5–6 ton medium excavators.
  • Q4: When should I replace the PVK-2B-505 pump?
  • A: Replace the pump if the 5–6 ton excavator has weak rock excavation power, slow compound action response, obvious high-temperature power drop after long-hour heavy operation, and insufficient flow leading to reduced construction efficiency.
  • Q5: What are the daily maintenance tips for PVK-2B-505?
  • A: Use clean high-grade anti-wear hydraulic oil and replace filter elements regularly to avoid particle wear on precision components; avoid long-term extreme overload and sharp impact operation; regularly check sealing and heat dissipation conditions to prevent internal leakage and high-temperature performance attenuation.
