Core Features:

• Tandem / Dual Pump Configuration: Two high-performance pumps in a compact, space-saving tandem arrangement, providing independent hydraulic power for multiple machine functions (e.g., boom, arm, bucket, swing) from a single drive source. The two pumps share a common suction port but have independent delivery ports .

• Robust Swashplate Design: The proven swashplate design with cast iron construction ensures reliable operation, excellent volumetric efficiency (up to 95%), and long service life in open circuit applications .

• High-Pressure Capability: Delivers 32 MPa rated and 35 MPa peak pressure (approximately 320-350 bar), meeting the most demanding excavator and construction application requirements .

• Excellent Suction Characteristics: Superior self-priming performance (up to 2,200 rpm) ensures reliable operation even in demanding conditions and at higher speeds, minimizing cavitation risks .

• Negative Flow Control: Standard negative flow control system provides excellent fuel efficiency and smooth operation, making it ideal for excavator applications .

• Through-Shaft Capability: The through-shaft design allows for the connection of additional hydraulic components, such as pilot gear pumps, providing flexible system configuration options .

• Durability: High-quality materials and stringent quality control processes ensure long service life in demanding continuous operation. Advanced sealing technology prevents internal leakage and minimizes wear and tear .

• Proven Reliability: With more than 25 years of experience in mobile applications, the K3V series offers field-proven performance and high reliability in demanding construction environments .

• Low Noise Operation: Optimized design ensures low noise levels during operation, meeting stringent workplace noise regulations .

• High Power Density: Compact design delivers exceptional power in a relatively lightweight package for easy installation .
