Characteristic features:
It adapts the gerolor design, which has a higher distribution accuracy.
Shaft seal is adapted, which can bear higher back pressure.
A variety of connection types of flange, output shaft and oil port.
Direction of shaft rotation and speed can be controlled easily and smoothly.
Small volume; compact structure.

Note：
1. Intermittent means the entrance of the maximum pressure; continuous working pressure means the differential pressure.
2. Motor should not work under the highest pressure and the maximum speed.
3. Recommending N68 anti-wear hydraulic oil, viscosity 37-73cSt, cleanO18/13.
4. The running time should not exceed 10% under intermittent working conditions
5. The Maximum working temperature is 80 ℃.
6. One hour running time under 40% of maximum working pressure is recommended before full capacity working.
7. The maximum allowable back pressure is 10MPa, but the recommended back pressure should not exceed 5MPa.a leaking pipes is needed when exceeding.
