oilgear hydraulic pumps
The development of the A4VTG90 series of hydraulic pumps stems from the company's more than ten years of global application experience in the construction machinery market. It is improved on the basis of the mature variable plunger pump to make it more suitable for use in the hydraulic transmission system of concrete mixer trucks.

Hydraulic components for industry mobile machinery;
Swash plate axial piston variable pump, suitable for closed loop hydraulic drive of mobile machinery;
The flow rate of a hydraulic pump is proportional to the speed and displacement of the pump;
The infinite variable can be realized by adjusting the angle of the swash plate;
When the swing angle of the swash plate passes the zero position, the liquid flow changes smoothly;
Two relief valves on the high-pressure side protect hydraulic components [pumps and motors] from overloading
Built-in auxiliary pump as charge and control oil pump
The maximum charge pressure is limited by the built-in charge relief valve
Rated working pressure can reach 40MPa
Choose long-life high-precision bearings
