BM1 Series orbital hydraulic motors are small volume hydraulic motors with design of spool valve and Geroler element. They have the following product features:
· Advanced design of spool valve and Geroler element, smaller size and compacter structure compared with other type hydraulic motors.
· Credible design of shaft seal, which can bear high pressure.
· Direction of shaft, rotation and speed can be controlled easily and smoothly.
· tepless speed variation, mini. stable speed could be 15r/m, easy to install, low costs.
· Could be used in parallel or in series connection in the hydraulic systems.
· Low rotation inertia, easy to start with load, both positive and negative rotation being allowed, and no need to stop the rotation for changing the rotation direction.
· High efficiency and economical, suitable for medium duty applications.
· A variety of connection dims. options of flange, output shaft and oil port.
