BMM Series Hydraulic Motor: Specifications, Features & Applications
BMM Series Hydraulic Motor Core Features
-
Compact & Lightweight Design: Adopting gerotor gear set and advanced structural design, the BMM series hydraulic motor features small volume and low weight, making it easy to integrate into various machinery and equipment, even in limited installation spaces.
-
High Efficiency & Long Service Life: Manufactured with advanced equipment for the gerotor gear set, the motor ensures high energy conversion efficiency and stable operation, effectively extending its service life in long-term work.
-
High-Pressure Shaft Seal: The shaft seal of the BMM hydraulic motor can withstand high pressure, allowing the motor to be used in parallel or series circuits, enhancing its versatility in different hydraulic systems.
-
Stable Performance: With axial oil distribution structure (or shaft distribution flow design), the motor maintains stable torque and speed output, even under intermittent operation conditions, meeting the requirements of various working scenarios.

BMM Series Hydraulic Motor Operation Notes
-
The normal oil temperature should be 20°C – 60°C, with a maximum of 90°C (no more than one hour).
-
System filtration should be 10 µm nominal, and a magnet is recommended to be installed in the filter or at the bottom of the oil tank to prevent contamination.
-
Recommended oil viscosity is 32 – 74 mm²/s, adjusted according to ambient temperature and application type.
-
The motor should be filled with oil before being put under load, and it is recommended to operate under 30% of rated pressure for the first hour to extend service life.
