Product Description
LIC Hydraulic’s Kawasaki K3V112 Series swash-plate axial piston pumps are the global benchmark for excavator hydraulic power. This series features the single pump K3V112S and the tandem configurations K3V112DT/DTP/DP, specifically engineered for 12 to 14-ton class machinery. We guarantee 100% Drop-in Interchangeability for iconic models such as Hitachi EX120-2/3 and Komatsu PC120-6. Built for extreme reliability and high power density, every K3V112 unit undergoes 100% dynamic load testing to ensure precise flow control and smooth multi-function movements under the harshest job site conditions.

Key Technical Advantages
Robust Rotating Group: The pistons and slippers are reinforced with specialized alloys to sustain high volumetric efficiency even after thousands of hours of high-pressure cycling.
High-Response Regulator: The integrated servo mechanism ensures rapid displacement adjustment, matching engine output perfectly to prevent stalling and maximize fuel efficiency.
Superior Contamination Resistance: The K3V series is renowned for its durability in dusty and high-vibration environments, offering a longer MTBF (Mean Time Between Failure) than many competitors.
Quiet & Stable Operation: Advanced port plate geometry and swash-plate damping reduce pressure ripples, leading to quieter operation and less fatigue on downstream hydraulic components.
Application Areas
Excavator Main Hydraulics: Powers the boom, arm, bucket, and swing functions.
Drilling Rigs: Provides consistent high-torque power for rotary drilling operations.
Heavy Lifting: Driving crawler tracks and winch motors on cranes.
Expert Maintenance Tips
Pre-Start Priming: Always pre-fill the pump case with clean hydraulic oil through the highest drain port before the first start. A dry start will result in immediate and catastrophic internal failure.
Inlet Line Inspection: Cavitation is the number one killer of K3V pumps. Check all suction hoses for leaks or collapses, and always replace the suction filter when installing a new unit.
Regulator Adjustment: If the excavator is “stalling” the engine or moving sluggishly, have a technician calibrate the regulator’s power setting. Do not attempt to dismantle the sensitive regulator springs without professional tools.
