Detailed Description

These axial piston pumps adopt a professional swashplate structure design, which ensures stable and reliable continuous operation and effectively extends the overall service life under various working conditions. The pump features excellent power performance, with a maximum working pressure of 420bar and a rated operating speed of 1800 min⁻¹, and it can also stably operate at higher speeds to meet diverse working demands. Equipped with oversize shafts and bearings, the pump boasts stronger load-bearing capacity and higher structural stability.
All rotating and pressure-bearing components adopt a precise pressure balance structure, which reduces internal wear and improves operational stability. It supports integrated configuration of pilot pump, filter and pressure relief valves for simplified installation and optimized system performance. Adopting a flexible building block design, the pump realizes strong universality and a wide range of application scenarios. Besides, it delivers fast response times, enabling sensitive and accurate hydraulic system control.
