Hydraulic Motor
 Spool Valve Motor
Characteristic features:
BM9 series motor adapt the advanced geroler gear set design with shaft distribution flow, which can automatically compensate in operating with high efficiency and long life.
Advanced manufacturing devices for the Gerolor gear set, which use low pressure of start-up, provide smooth, reliable operation and high efficiency.
Shaft seal can bear high pressure of back and the motor can be used in parallel or series.
Special design in the driver-linker and prolong operating life.
Special design for distribution system can meet the requirement of low noise of unit.
volume and easy installation.

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. The running time should not exceed 10% under intermittent working conditions.
4. Recommending N88 anti-wear hydraulic oil. Viscosity 37-73cSt, cleanliness ISO18/13.
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.
