Open the catalog to page 21 General information External gear motors are widely used in modern hydraulic systems due to their high performance, long service life and low maintenance costs. With the new APM212HP family, high operating pressures, excellent volumetric and mechanical efficiencies were achieved; moreover, for LN-series (Low Noise versions), definitely better acoustic performances were obtained. Different features of the new APM design were deeply analyzed and studied in order to get to the above mentioned results; primarily, engineering attention was focused on the design of the gear teeth and balancing...
Open the catalog to page 31.2 Fan Drive Gear Motors for cooling systems In the Fan Drive Gear Motors for cooling systems we implemented the shaft seal protection adding a dedicated sealing. Consequently, dedicated cast iron front covers have been designed. See section 3.4.2 Dedicated front cover with additional dust protection Improve machine operating efficiency Allow to integrate hydraulic values circuit Reduce the costs of maintenance Electronic control available Reduce noise and vibrations Examples of typical applications Telehandler Large Wheel loader Hydraulic scheme examples

The mechanical stress localised on threaded ports cause a reduced motor life performances IMPORTANT!: Please consult Bucher Hydraulics if even one of the operating limits indicated in the table (temperature, pressure, rpm) is exceeded, as well as in the case of two or more maximum values at the same time, or for applications with particularly heavy-duty cycles 1.5 High inlet pressure Pressure levels: P1 = continuous...
Open the catalog to page 61.6 Identifying the rotation direction The rotation direction of a gear motor is identified by looking at the motor from the front and with the drive gear turned up wards (see figures below). The figure also shows the pressure flow inside the motors as the oil is transferred from the inlet port to the outlet port. As regards reversible motors (R), the ports are alternatively for inlet and outlet. Motors with a unidirectional rotation (D or S) have the de nomination APM. Motors with reversible rotation have the denomination APMR. Motors with “Low Noise” components have the denomination LN....
Open the catalog to page 71.8 Radial and axial load 1.8.1 Standard version Bucher APM212 gear motors are suitable to work also when radial and axial loads are applied to it. In order to guarantee the correct life of the hydraulic motor, it is necessary to let the component work within the limits indicated in the table below: 1.8.2 Bearing front cover support High values of radial and axial loads can cause the wear of the motor internal components; as a consequence, motor performance and life can be dramatically reduced. Bucher Hydraulics studied special front covers having a bearing on-board which allow the motor to...

Different solutions are available depending on pressure value recorded. See examples from 1 to 4 Pressure [bar] 10 8 These limits have 6 to be respected in 4 the worst working 2 conditions 0 Standard shaft seal Outlet pressure must be remain inside L area Bidirectional motor used in only one direction DRAIN Unidirectional motor with drain line (drain pressure must be remain inside L area) Standard shaft seal OUT OUT IN High...
Open the catalog to page 9In addition to the recommendations regarding fluids, filtration, coupling, etc., we suggest the following: - For unidirectional motors check always the rotation direction of the motor's take off shaft; it must be compatible with the rotation direction of the motor itself. - Be particularly careful in cleaning and make sure, when connecting the high and low pressure piping, that no chips, rag threads, teflon tape, etc. get into the motor circulation system. - Check the tightness of the high and low pressure fittings, the correct positioning of the O-Ring, and make sure there is no dirt...

Open the catalog to page 11218 In the next pages, front, rear cover, and seals materials are listed for each motor series. For ordering purposes, it is enough to outline the complete motor description (for example: APM212HP/15 D 218). In case of a different configuration request (or a combination of different features, such as port threads, front flange materials, etc.), the description configurator shown in section 3.1 can be easily used. This motors configuration are considered as “standard”. 2.1 Standard configuration Front cover type (cast iron made) Drive shaft
