_Flow rate is proportional to driving speed and displacement and can be variable steplessly.

The flow rate increases from zero to its maximum with the swashplate swing angle.

The liquid flow direction can be changed smoothly by making the swashplate swing over the middle.

Variable modes that are easily matched with various control and regulation systems;

The pump is equipped with two relief valves at the high pressure oil side to protect the hydrostatic transmission (pump and motor) from overloading.

High pressure relief valve also has the function of filling valve.

Built-in auxiliary pumps are used as refueling pumps and control pumps.

The maximum filling pressure is limited by a built-in filling relief valve.
