BMM Hydraulic orbit motors

BMM series motor are small volume,economical type,which is designed with shaft distribution flow, which adapt
the Gerotor gear set design and provide compact volume,high power and low weigth.

Characteristic features:
* Advanced manufacturing devices for the Gerotor gear set, which provide small volume, high efficiency and long life.
* Shaft seal can bear high pressure of motor of which can be used in parallel or in series.
* Advanced construction design, high power and low weight.
