BMR Series Hydraulic Motor

BMR series motor adapt the advanced Gerolor gear set design with shaft distribution flow, which can automatically compensate in operating with high pressure , provide reliable and smooth operation, high efficiency and long life.   

Characteristic Features:
   *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 in 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.
   *Compact volume and easy installation.
