Mini Hydraulic Motors, Micro Hydraulic Motors, Small Hydraulic Motors
Descriptions:
BMM series mini hydraulic motor are small volume, economical type, which is designed with shaft distribution flow, whichadapt the Gerotor gear set design and provide compact volume, high power and low weigt.
Characteristic features:
1. Intermittent means the entrance of the maximum pressure;continuous working pressure means the differential pressure.
2. The running time should not exceed 10% under interoittent working conditions.
3. The maximum working temperature is 80°.
4. The maximum allowable back pressure is 10MPa,but the recommended back pressure should not exceed 5MPa.a leaking pipes is needed when exceeding.
Applications:
The Small motor have widely applications, such as the following:
1. Construction equipment
2. Agricultural equipment
3. Material handling & Lifting equipment
4. Forestry equipment
5. Lawn and turf equipment
6. Special purpose
7. Machine tools and stationary equipment
8. Marine equipment
