K3V63DT / K3V63DTP are variable axial piston pumps from Kawasaki's K3V series, designed for mobile hydraulic systems in construction machinery. They offer high power density, efficiency with low noise, long service life, and flexible control, excelling in medium- to high-pressure applications such as excavators. Detailed features are as follows:
Key Features
High Power Density:
Semi-log swashplate design increases rated pressure while significantly improving power density (output power per weight). The compact, lightweight structure with dual pump series layout eliminates the need for a power distributor, enhancing transmission efficiency and saving installation space.
Efficient, Low Consumption & Strong Suction:
Spherical valve plate and optimized hydraulic balance ensure stable rotation, maintaining high efficiency even at low pressure and speed. Maximum self-priming speed reaches 2,650 min⁻¹, minimizing cavitation risk and ensuring stable oil supply under complex conditions.
Long Life & High Reliability:
Large-capacity main bearings combined with a plunger return mechanism that compensates for slipper wear reduce key component wear. With over 25 years of mobile hydraulic application experience, rated pressure is 34.3 MPa and maximum pressure up to 39.2 MPa, ensuring stable operation under high-pressure heavy loads.
Low Noise Design:
Optimized valve plate design and reinforced housing effectively reduce operational noise, improving the working environment.
Versatile Control Options:
Supports mechanical, hydraulic, and electric control inputs, enabling precise flow and pressure regulation for complex operating requirements.
Flexible Structural Adaptation:
Offers multiple cylinder block rotation configurations, including series layout with PTO and parallel cylinder block layout. K3V63DTP typically features a dual-pump structure for flexible integration into different hydraulic systems.
