description

The K5V212 hydraulic pump adopts an aviation-grade reinforced ultra-heavy integral swash plate variable structure, with core friction pairs such as plunger, cylinder block and valve plate processed by ultra-precision mirror grinding technology. The internal matching clearance is controlled at sub-micron precision, effectively minimizing friction loss during 24-hour non-stop ultra-heavy cyclic operation and comprehensively upgrading wear resistance, pressure holding stability and fatigue resistance. The internal super-large flow channel adopts optimized fluid dynamic design, which greatly reduces hydraulic circulation resistance and heat accumulation, achieving rapid heat dissipation and stable power output without obvious temperature rise or power attenuation under continuous full-load mining conditions. The pump body is integrally forged with high-purity ductile iron with internal stress elimination treatment, featuring ultra-high compression resistance, explosion-proof vibration resistance and extreme impact resistance, fully adapting to ultra-harsh working environments such as violent rock impact, high-corrosion muddy water erosion and long-term high-frequency alternating load in open-pit mines.

advantages

  • 212ml/r Top-Tier Displacement, Explosive Mining Power: Adopting industry-max 212ml/r twin displacement design, the K5V212 provides super-large flow and ultra-high pressure output. It completely solves the power bottleneck of K5V200 pumps in ultra-hard rock breaking and super-deep excavation, maintaining continuous and explosive power output for full-load extreme mining operations of 48–52 ton ultra-heavy excavators.
  • Upgraded Ultra-Heavy Variable Logic, Smoother Extreme Actions: Equipped with upgraded mine-specific variable control algorithm, the pump intelligently matches flow and pressure according to drastic load fluctuations. The switching between light load and extreme heavy load is seamless without stuttering, effectively eliminating jitter, lag and uncoordinated linkage of ultra-heavy excavators under frequent impact loads.
  • Leading Full-Load Heat Resistance, 24/7 Non-Stop Operation: The super-large optimized internal flow channel minimizes hydraulic energy loss and heat accumulation. Even during round-the-clock uninterrupted full-load hard rock mining, the oil temperature rises gently without power limitation or shutdown protection, ensuring continuous and efficient operation of large open-pit mine projects.
  • Sub-Micron Wear-Resistant Core, Permanent Stable Pressure Holding: Core friction pairs adopt customized ultra-hard alloy + sub-micron mirror grinding process, achieving near-zero wear rate under cyclic extreme load. It fundamentally avoids common faults such as internal leakage, pressure drop and arm drifting, keeping the hydraulic system in peak working condition for a long time.

FAQ

  • Q1: What tonnage and models does the K5V212 pump fit?
  • A: The K5V212 hydraulic main pump is tailored for 48–52 ton ultra-heavy excavators, perfectly compatible with Sany SY485/SY500/SY600, XCMG XE490, Lonking, Kobelco SK460/SK485 and other mainstream ultra-heavy models, focusing on open-pit mine heavy-duty working conditions.
  • Q2: What faults require K5V212 pump replacement?
  • A: If the excavator has weak ultra-hard rock breaking power, slow full-load compound actions, frequent pressure drop in mining operation, excessively high hydraulic oil temperature and jittery linkage under extreme load, the original pump is severely worn and loses pressure holding capacity, requiring timely replacement.
  • Q3: Is modification needed for installation?
  • A: No modification required. The K5V212 pump is manufactured strictly according to OEM ultra-heavy machine standards, with fully consistent hole positions and high-pressure interfaces, supporting plug-and-play direct installation for rapid on-site overhaul.
  • Q4: What is the difference between K5V212 and K5V200?
  • A: The K5V212 has larger total displacement, higher 39.2MPa peak pressure, stronger low-speed torque and better high-temperature stability, specially designed for 48–52 ton ultra-heavy mining excavators. The K5V200 is only suitable for 45–50 ton general heavy earthwork equipment, with insufficient power reserve for ultra-hard rock extreme working conditions.
  • Q5: How to maintain the K5V212 pump for longer service life?
  • A: Adopt high-grade anti-high-temperature hydraulic oil and filter elements to ensure ultra-clean oil circulation. Avoid long-term extreme overload impact operation. Regularly inspect high-pressure pipeline aging and leakage. Standard professional maintenance effectively delays core component wear and maintains long-term peak performance.
