K3V122DT Axial Piston Pump

K3V122DT  Axial Piston Pump Overview

The K3V122DT axial piston pump is a high-performance swash plate type axial variable displacement piston pump, which is a customized enhanced version of Kawasaki K3V112DT series. It adopts a tandem double pump structure, integrates a pilot gear pump, and is specially designed for 20–25 ton hydraulic excavators. With stable high-pressure performance, high efficiency and strong reliability, it is widely used in medium-sized construction machinery such as excavators, loaders and crawler drills, providing stable and efficient power support for hydraulic systems in harsh working conditions such as construction sites and mines. It is compatible with mainstream construction machinery brands such as Sany, Komatsu, Hyundai and Doosan, and is a benchmark main pump in the 20–25 ton class.

Core Features & Advantages

• High Efficiency & Energy Saving：Adopting advanced spherical valve plate and hydraulic balance design, it maintains high volumetric efficiency even in low-speed and low-pressure ranges, minimizing energy loss during power transmission. The standard negative flow control system can adjust displacement in real time according to working conditions, realizing the perfect matching of power output and load demand, effectively reducing fuel consumption of construction machinery and improving operational economy. At the same time, the optimized oil circuit design ensures sufficient lubrication of internal components and reduces friction loss.
• High Reliability & Long Service Life: It adopts reinforced main bearings, wear-resistant cylinder blocks, high-hardness pistons and wear-compensating slippers, which can withstand long-term heavy-load impact and intermittent peak pressure of 39.2 MPa. The modular design reduces the number of parts, improves the universality of parts, and extends the service life in harsh working conditions such as mines and construction sites. With more than 25 years of mature application experience in mobile machinery, the cumulative sales volume is huge, and the reliability has been fully verified.
• Compact Structure & Easy Installation: The tandem double pump integrated design, two pump cores share one main shaft, which improves the utilization rate of installation space and is suitable for the layout of 20–25 ton excavators. The standard port layout (side oil suction, bottom oil outlet) is optimized for medium-sized excavators, which is convenient for installation and connection, and the installation size is consistent with K3V112DT, which can be directly replaced.
• Low Noise & Stable Operation: The optimized design of the valve plate and rigid pump housing effectively reduces fluid pulsation and mechanical vibration during operation, significantly reducing the overall noise level. The optimized rotating component design and static pressure balance bearing ensure stable cylinder rotation, low vibration and quiet operation, creating a more comfortable working environment for operators.

• Strong Adaptability & Wide Compatibility: It has excellent adaptability to complex working conditions such as high altitude and low temperature, and the reliable self-priming performance effectively reduces the risk of cavitation and ensures continuous and stable operation. It supports multiple control modes, which can accurately match the needs of complex actions of construction machinery. It is widely compatible with 20–25 ton excavators of various brands, with a complete accessory system and convenient maintenance and replacement of vulnerable parts (valve plate, piston, slipper).

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
