XB01VG series swash plate type axial piston variable displacement pump is used in the closed circuit of hydrostatic transmission. The flow rate is proportional to the driving speed and displacement and can be infinitely variable. Various variable control methods can be selected, such as manual, hydraulic control, and electric ratio Control, etc. Multiple hydraulic control valves can be integrated to avoid overload. Different control methods can be configured according to customer needs. The degree of automation is high. Remote control operations can be realized. The through-shaft design is used to meet the various needs of the hydraulic system. Can replace imported Rexroth A4VG series axial piston pump.

Technical Feature
Axial piston variable displacement pump with swash plate structure for hydrostatic transmission in closed circuit
The flow is proportional to the driving speed and displacement and can be adjusted steplessly
Output flow increases from zero to maximum with swashplate swing angle
A variety of highly compatible control equipment, providing various control and adjustment functions
Each high pressure side is equipped with two relief valves to prevent the hydrostatic transmission (pump and motor) from overloading
Relief valve also has charge valve function, built-in pressure shut-off valve is standard
Built-in charge pump is used as fuel supply and control pump. The maximum charge pressure is limited by the built-in charge relief valve.
