BMV Series Hydraulic Motor
Products: Orbital Hydraulic Motors
The BMV series of cycloidal hydraulic motors are advanced hydraulic motors featuring a face-port distribution design. This series utilizes a column-type rotor-stator assembly and is characterized by high operating pressure, high efficiency, excellent overall efficiency retention, and a long service life. Based on the standard design, multifunctional variants can be customized to meet specific user requirements.
Description:
BMV orbital hydraulic motors are designed for heavy-duty mobile machinery and industrial hydraulic systems requiring high torque, high flow and reliable load capacity. With nominal displacements from 315 to 1,000 cm³/rev., continuous working pressure differences up to 20 MPa and continuous torque up to 2,050 N·m, the series provides a powerful drive solution for demanding hydraulic applications.
