description

The K5V80 hydraulic pump adopts an optimized integral swash plate variable structure, with core friction pairs including plunger, cylinder block and valve plate processed by high-precision grinding technology. The internal matching clearance is precisely controlled to reduce operating friction loss and improve overall wear resistance. The upgraded internal flow channel structure balances flow output and heat dissipation efficiency, effectively restraining heat accumulation during long-hour medium-load operation and avoiding performance attenuation caused by high temperature. The pump body is integrally cast with high-strength alloy cast iron, featuring good compression resistance, vibration resistance and structural stability, adapting to complex construction site environments with dust, mud and frequent load switching. All finished pumps undergo strict factory pressure resistance and fatigue tests, with stable displacement and accurate variable adjustment. It can perfectly restore the original flexible operation and stable power performance of 13–16 ton medium excavators, solving old equipment defects such as slow response, weak partial load operation and easy hydraulic heating.

advantages

  • Optimized K5 Series Variable Technology, Smoother Operation: Different from traditional K3V series pumps, the K5V80 adopts upgraded variable control logic with more precise flow adjustment. It can intelligently match power output according to medium-load changes, ensuring smooth switching between light and medium loads, effectively improving jitter and uncoordinated linkage of medium excavators.
  • Sensitive Low-Speed Response, Low Energy Consumption: The pump features excellent low-speed performance with stable pressure output during idle and micro-operation. It solves the problem of slow low-speed action and weak fine operation of ordinary pumps, reducing idle power loss and lowering equipment overall fuel consumption.
  • Balanced Heat Dissipation, Stable Continuous Operation: The optimized internal flow channel reduces hydraulic resistance and heat accumulation. It maintains a gentle temperature rise during long-term continuous medium-load operation, avoiding power limitation and efficiency drop caused by hydraulic overheating, ensuring all-day stable construction.
  • High Wear Resistance, Low Failure Rate: Core friction pairs are made of high-quality wear-resistant alloy with precision grinding process, achieving low internal wear rate. It effectively prevents internal leakage, pressure drop and other common faults, maintaining long-term stable hydraulic system pressure.

FAQ

  • Q1: What excavator tonnage does the K5V80 hydraulic pump fit?
  • A: The K5V80 hydraulic main pump is specially designed for 13–16 ton medium-sized excavators, focusing on medium-load municipal and earthwork construction scenarios, with strong compatibility with mainstream 14–15 ton equipment models.
  • Q2: What symptoms mean the K5V80 pump needs replacement?
  • A: If the excavator has weak medium-load digging, slow low-speed fine operation, unsmooth compound linkage, frequent hydraulic pressure drop and abnormally high oil temperature during continuous operation, the original main pump is severely worn and needs timely replacement.
  • Q3: Is equipment modification required for installation?
  • A: No modification is needed. The K5V80 pump strictly follows original factory standard dimensions with consistent hole positions and interfaces, supporting plug-and-play direct installation for on-site rapid maintenance.
  • Q4: What is the difference between K5V80 and K3V63 pumps?
  • A: The K5V80 has larger displacement and better low-speed response, suitable for 13–16 ton medium-load excavators. The K3V63 is mainly for 12–15 ton light-medium equipment with weaker fine operation and continuous heat dissipation performance.
  • Q5: How to maintain the K5V80 pump to extend service life?
  • A: Regularly replace qualified hydraulic oil and filter elements to keep the oil circuit clean. Avoid long-term overload operation. Regularly check pipeline blockage and leakage to ensure stable hydraulic circulation and delay pump core aging.
