External Gear Motors, Series APM
Description
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
Internal Gear Motor QXM-Mobil
Description
The QXM-Mobil internal gear motor was specifically developed for use in mobile applications. Its outstanding efficiency and extremely low noise levels also make a significant contribution to reducing the costs of both energy and anti-noise measures. The QXM design principle, featuring an integral outboard bearing, ensures top-class protection against leakage at the shaft seal.
Internal-Gear Motor, Series QXM-HS
Description
The QXM-HS (High Speed) internal-gear motor was developed specifically for use at extremely high speeds. Its first-rate efficiency and extremely low noise levels also make a significant contribution to reducing the costs of both energy and anti-noise measures.
Thanks to the special motor flange, adapted for such applications, and the integral ports for auxiliary functions, the motor can be used in many applications without needing any further modification.
QXEM Internal Gear Units
Description
Highly dynamic variable-speed multi-quadrant applications
The QXEM series is intended for operation as both a pump and a motor. A symmetrical design makes these units specially suitable for highly dynamic variable-speed multi-quadrant operation. In the industrial hydraulics field, they are therefore particularly appropriate for applications with highly cyclical loading. Thanks to the pinion-shaft technology, pressures up to 250 bar are built up in a single-stage. The direction of rotation can also be reversed in milliseconds, while maximum operational reliability is ensured at all times thanks to optimized hydrodynamic lubrication.
QXM Internal Gear Units
Description
Pump/motor operation in multi-quadrant applications
The QXM series is an extension of the QX pump series and is suitable for operation as both a pump and a motor. Thanks to the completely symmetrical design, these units can be used in multi-quadrant operation and are suitable for a wide range of applications in both industrial and mobile hydraulics. In 4-quadrant operation, the movement of cylinders can be controlled on the one hand, and exploited to recover/save energy on the other. For example, if the unit works as a pump during a lifting process, it can then work as a motor during the lowering process to feed energy back into the system.
