Core Features:

• Next-Generation K7V Series: The K7V series incorporates Kawasaki's latest technologies for improving efficiency and lowering noise, achieving the world's top-level pump efficiency which contributes to energy savings on applications and a comfortable working environment .

• Ultra-Low Noise Operation: By optimizing internal clearances and stabilizing the cylinder block rotation, the K7V series achieves significantly reduced noise levels compared to conventional pumps, making it ideal for noise-sensitive urban job sites .

• High Power Density: With 1.5 times higher power density than the K3V series, the K7V delivers exceptional power output in a more compact package, enabling machine downsizing without compromising performance .

• Tandem / Dual Pump Configuration: Two high-performance pumps in a space-saving tandem arrangement, providing independent hydraulic power for multiple machine functions (e.g., boom, arm, bucket, swing) from a single drive source .

• PTO (Power Take-Off) Capability: The "P" in DTP indicates this model features a through-shaft PTO, allowing for the connection of additional hydraulic components such as pilot gear pumps, providing flexible system configuration options .

• Optimized Axial Length: The axial dimensions have been optimized, achieving a 10% shorter overall length compared to the K3V series, saving valuable installation space in compact machinery .

• Extended Service Life: By adopting large capacity bearings and increasing the drive shaft size, the edge load on bearing rollers is reduced, achieving even longer service life .

• High-Pressure Capability: Delivers 35 MPa rated and 40 MPa peak pressure, meeting the most demanding excavator and construction application requirements .

• Excellent Suction Characteristics: Superior self-priming performance (2,650 min⁻¹) ensures reliable operation even in cold start conditions and challenging intake situations .
