    Bucher QXM Gear Pumps / Motors


    The Bucher QXM gear pump / motor (drive unit) can be used in open- and closed-loop hydrostatic drives – operating as both 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.

    Features and benefits include:

    • Up to 70% energy saving;
    • Up to 20 dB (A) quieter;
    • Saving valve technology;
    • Use with variable-speed drives;
    • 2 and 4 quadrant operation possible.

    The Bucher QXM is available in displacements from 5.1 cc/rev to 495.4 cc/rev: QXM21-010 | QXM21-012 | QXM21-016 | QXM31-020 | QXM31-025 | QXM31-032 | QXM41-040 | QXM41-050 | QXM41-063 | QXM51-080 | QXM51-100 | QXM51-125 | QXM61-160 | QXM61-200 | QXM61-250 | QXM81-315 | QXM81-315 | QXM81-400 |QXM81-500
