Description
The BMM series orbital hydraulic motor is a miniature shaft distribution motor that can be installed and used in a small space. It adopts insert column type rotary stator pair, 4/5 tooth structure, compact structure, light weight and high power density. Its characteristics:
• The use of advanced stator parameters design, low starting pressure, high efficiency, and good retention, smooth operation.
• High shaft seal pressure, can be used in series and parallel.
• Advanced structure design, high power density.

* The rated speed and torque refer to the output value under the rated flow and pressure.
* Continuous value refers to the maximum value that the displacement motor can work continuously.
* The intermittent value refers to the maximum value of the displacement motor working for 6 seconds in 1 minute.
* The peak value refers to the maximum value of the displacement motor working for 0.6 seconds in 1 minute.
