External gear motors, series APM

The essential components of series APM 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.

Advantages

High overall efficiency thanks to optimised hydraulic compensation
Optimum quality/price ratio
Customised models can be built for specific applications
Low maintenance requirements, even in heavy-duty operating conditions
Various components and accessories are available for radial/axial loads, integral anti-cavitation valve, etc.

Models

Unidirectional
Reversible (model code APMR)
With integral anti-cavitation valve
With outrigger bearing for axial and radial loads (not APM05)

Applications

Agricultural machines
Construction machinery
Winches
Harvesting machines
Hydraulic tools

Gerotor Motors

gerotor motor

Gerotor motors are slow speed / high torque motors.
The power element of this motor is the power unit, comprising rotor, outer ring (stator) and 7 cylinders.

The patented rotor profile prevents direct leakage between the pressure chambers, resulting in negligible internal leakage and high volumetric efficiency.

Advantages

Without drain line
Integrated speed sensor
Integrated valves
Parking brake or wheel hub

Internal Gear Unit QXM

internal gear unit QXM

The QXM drive unit can be used in open- and closed-loop hydrostatic drives, and can operate both as a pump and as a motor.
The QXM works as a pump to lift the load and it can recover energy when the load is being lowered.
Used as a bi-directional pump / motor (four-quadrant operation), the unit can control the complete motion cycle of a cylinder.

Advantages

Very low noise levels
Negligible pressure pulsations
Long service life
Suitable for special fluids
4-quadrant (fully bi-directional pump / motor) or 2-quadrant operation is possible
Low susceptibility to cavitation

Applications

Winches
Fork lift for high rack facility
Lift hydraulics with energy recovering
Fork lift trucks with energy recovering
Lifting Platforms
Drive for roller coasters
