QXEM22-005N Internal Gear Pump/Motor Unit 5.1 cm³/rev 250 bar

The QXEM22-005N internal gear unit from the Bucher Hydraulics QXEM series is a compact unit designed for both pump and motor operation. With a nominal displacement of 5.1 cm³/rev and a continuous operating pressure of 210 bar (250 bar peak), this component is ideal for variable-speed multi-quadrant applications. The symmetrical design with pinion-shaft technology ensures minimal pulsation even at low speeds.
