QXEM42-032N Internal Gear Pump/Motor Unit 32.3 cm³/rev 250 bar

The QXEM42-032N by Bucher Hydraulics is an internal gear unit from the QXEM series, capable of operating as both a pump and a hydraulic motor with reversible rotation. With a displacement of 32.3 cm³/rev and a continuous pressure of 210 bar (250 bar peak), it is designed for multi-quadrant applications requiring consistent flow rates and fast dynamic response. The integrated pinion-shaft technology guarantees extremely low pressure and flow pulsations.
