Product Description
The Rexroth A7VO tilt-axis piston pump is an important hydraulic transmission equipment, which adopts a tilt-axis axial conical piston rotor group and is designed for open-circuit hydrostatic transmission. This transmission method is widely used in mobile and fixed equipment, such as construction machinery, agricultural machinery, mining machinery and other fields.
Performance characteristics and contact information
For technical parameters, physical drawings, dimensions and other information of Rexroth piston pumps, please contact Poocca immediately. The flow rate of Rexroth piston pumps is proportional to the transmission speed and displacement, and can be adjusted steplessly between the maximum flow rate (qv max) and the minimum flow rate (qv min = 0). This means that in various application scenarios, the equipment can adjust the flow rate according to actual needs and provide flexible operating options.
Structure and control
The A7VO hydraulic piston pump is equipped with a variety of control devices, such as solenoid valves and proportional valves. Users can choose the appropriate control device according to specific needs to achieve precise and efficient hydraulic transmission. Its compact structural design and powerful bearing system ensure excellent performance in long-term use, reduce the frequency of maintenance and replacement, and save costs and time for users.
