- Swashplate axial plunger variable pump for closed circuit hydrostatic transmission.
- Flow rate is proportional to driving speed and displacement.
- 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 can be easily matched with different 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 functions as filing 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.
- Full series with built-in pressure shut-off valves.
