  • Compact structure with lightweight cast aluminum housing and direct drive from the main pump shaft.
  • Convenient modular installation allows for simple replacement without major disassembly of the main pump.
  • Designed for 40-50 ton large excavators including SK460-8, SY485H, R455, ZAX450, and 349 models.
  • Self-priming gear pump design with specific involute spline specifications for secure mounting.
FAQs:
  • Which excavator models is the K5V200 pilot pump compatible with?
    The K5V200 pilot pump is specifically designed for 40-50 ton large hydraulic excavators, including models such as SK460-8, SY485H, R455, ZAX450, and 349.
  • What are the key advantages of using this pilot pump?
    This pump offers high reliability with a long lifespan, stable pilot pressure output for smooth main pump operation, high efficiency with ≥92% volumetric efficiency, low noise and vibration, and a compact design for easy maintenance and replacement.
  • What maintenance precautions should be taken when using this pilot pump?
    Never start the machine without hydraulic oil or with insufficient oil level. Use clean, high-quality anti-wear hydraulic oil with contamination level no lower than NAS 9. Avoid prolonged overload operation and preheat the machine at low speed under no-load for 5-10 minutes when starting cold until oil temperature reaches above 30°C before heavy-load operation.
  • What is the nominal displacement and operating pressure of the K5V200 pilot pump?
    The K5V200-15L model has a nominal displacement of 15 mL/r, with a rated pressure of 3.5 MPa and a pull pressure of 5 MPa, operating at an optimum speed range of 1500-2500 r/min.
