Product Features

High - efficiency Performance

• Adopting advanced piston design, it can effectively reduce energy loss and improve the overall efficiency of the hydraulic system. Under different working conditions, it can maintain high volumetric efficiency and mechanical efficiency, reducing energy consumption.
• It has a fast response speed and can quickly adapt to load changes to ensure the stable operation of the system.

High Reliability

• The key components are made of high - quality materials, and have undergone strict quality inspections and treatments. They have good wear resistance and corrosion resistance, and can work stably for a long time in harsh environments.
• The design is compact and the structure is reasonable, which reduces the probability of failures and lowers the maintenance cost.

Multiple Control Modes

• EP4D: It has an electronic proportional control function, which can accurately adjust the pump's displacement according to the input signal to achieve precise control of the hydraulic system.
• EZ: It is a simple control mode, easy to operate, and suitable for occasions with low requirements for control accuracy.
• DA: Load - sensitive control, which can automatically adjust the pump's displacement according to the system load to improve energy utilization efficiency.
• HW: Manual control mode, which can be manually adjusted in special cases.
• EP2D: Dual - proportional control, which can implement more complex control strategies.
