Kawasaki K5V Series Pump | K5V160DTH, K5V140DTP, K5V80DTP | Excavator Main Hydraulic Pump

Kawasaki K5V Series High-Pressure Main Pump for Excavators

Product Overview: The Kawasaki K5V series is the globally recognized premium power core for the construction machinery industry. Developed as the evolutionary successor to the K3V series, the K5V is engineered for harsher digging conditions, covering key displacements from 80cc (K5V80) and 140cc (K5V140) to 160cc (K5V160). Flagship models such as the K5V160DTH (High-pressure tandem pump) and K5V140DTP (Tandem pump with pilot control) deliver precise flow output under a continuous pressure of 34.3 MPa. It is widely adapted for 20 to 40-ton excavators, ensuring smooth multi-function synchronization and formidable breakout force.

Key Technical Advantages:

• Superior Power Density & Longevity: Rated for a continuous operating pressure of 34.3 MPa (343 Bar) with peak capabilities up to 39.2 MPa. Reinforced rotating groups and heavy-duty bearings significantly extend service life in high-load mining environments.

• High-Response Precision Control (-9T16-BV / -9N0A-V):

  • Integrates advanced regulator technology supporting Negative Flow Control (NFC), Positive Flow Control, and Total Power Control.

  • DTH/DTP Architecture: Ensures perfect synchronization of power distribution between the tandem units, effectively reducing system heat generation.

• Low Noise & Anti-Vibration Design: Optimized valve plate designs suppress fluid pulsations. Combined with a rugged housing, this drastically reduces operating noise and enhances impact resistance.

• Highly Integrated Customization:

  • U9R/1X4R/1G9R Configurations: Represent customized shaft ends and port interfaces tailored for global excavator brands (e.g., Hitachi, Volvo, SANY, Hyundai), ensuring 100% “plug-and-play” compatibility.

• Exceptional Suction & High-Speed Performance: Optimized inlet flow paths enhance self-priming speed limits, maintaining stable suction efficiency even in high-altitude or low-temperature conditions.
