Kawasaki K3V Series Main Pump | K3V63, K3V112, K3V140 | 34.3MPa Double Hydraulic Pump

Kawasaki K3V Series Double Axial Piston Variable Pump

Product Overview: The Kawasaki K3V series is the globally recognized benchmark for heavy-duty hydraulic pumps in mobile machinery, particularly dominant in 6 to 30-ton excavators. This series, including the K3V63DT, K3V112DT, and K3V140DT, features a swashplate-type double pump design where two pumps share a single drive shaft. Renowned for its exceptional reliability, high power density, and advanced regulator controls, the K3V series delivers ultimate power response during high-intensity digging and load cycles.

Key Technical Advantages:

• Superior High-Pressure Performance: Rated for a continuous operating pressure of 34.3 MPa (343 Bar) with peak cycles up to 39.2 MPa. Refined piston groups and valve plates ensure peak volumetric efficiency under grueling job site conditions.

• Precise Power Modulation (Regulator): Models like the K3V63DT-1D1L and K3V112DTP are equipped with high-precision regulators supporting Negative Flow Control (NFC) or Positive Flow Control. This ensures pump output perfectly matches engine power, optimizing fuel efficiency and preventing engine stalls.

• OEM-Grade Compatibility: Suffixes such as GN26-1 or 0E11-AV specify mounting flanges, gear pump couplings, and port configurations, ensuring a 100% direct “plug-and-play” replacement for excavator brands like Hitachi, Sany, and Doosan.

• Low Noise & Extended Durability: Optimized swashplate support designs significantly reduce operational vibration, extending bearing life while enhancing operator cabin comfort.
