The essential components of series APM212 external gear motors are an aluminium alloy body and two gearwheels supported by plain bearings.

The front flange can be the SAE standard, or the British or German OEM patterns.

Particular attention has been focussed on the design of the shaft seal, which is often affected by back-pressures
