The K3V112DT/K3V112DTP is a 112mL/r variable displacement swashplate axial piston pump from the Kawasaki K3V series. It belongs to the same series as the K3V63DT/DTP, sharing the same core features and advantages, but with a larger displacement. It is suitable for medium to large-sized construction machinery such as 20-25 ton excavators, with a rated pressure of 34.3MPa and a maximum of 39.2MPa, offering stronger power and greater flow. The following is a detailed introduction:

1. High Power Density: The semi-logarithmic swashplate design increases rated pressure and power density, resulting in a compact and lightweight structure. The K3V112DTP is mostly arranged in a double series configuration, eliminating the need for a power distributor, resulting in higher transmission efficiency, lighter weight, and saved installation space.

2. High Efficiency, Low Consumption, and Strong Self-Aspiration: A spherical distribution plate and optimized hydraulic balance ensure stable cylinder rotation and high efficiency even at low pressure and low speeds; the maximum self-aspiration speed reaches 2360 min⁻¹, providing excellent oil suction performance, reducing cavitation risk, and adapting to complex operating conditions.

3. Long Life and High Reliability: A large-capacity main bearing and a piston reset mechanism with wear compensation for slipper wear reduce wear on critical components; over 25 years of experience in mobile hydraulic applications ensures long-term stable operation under high pressure and heavy loads.

4. Low-Noise Design: Optimized distribution plate and enhanced housing rigidity effectively reduce operating noise and improve the operating environment.

5. Diverse Control Methods: Supports multiple control inputs including mechanical, hydraulic, and electrical, allowing precise adjustment of flow and pressure to meet the needs of complex and delicate operations.

6. Strong Structural Adaptability: Offers tandem and parallel cylinder configurations with PTO; the K3V112DTP is a dual pump, flexibly adaptable to different hydraulic system architectures.

Energy Efficiency | Variable displacement adjusts flow rate on demand, reducing energy consumption and heat generation, lowering fuel consumption, and significantly reducing long-term operating costs.Wide Adaptability | Rated 34.3MPa/Maximum 39.2MPa, suitable for medium and high pressure conditions in excavators, cranes, loaders, etc., with strong adaptability to load fluctuations.
