QXEM22-008N Internal Gear Pump/Motor Unit 7.9 cm³/rev 250 bar

The QXEM22-008N internal gear unit from the Bucher Hydraulics QXEM series is a versatile solution for industrial pump/motor applications. Featuring 7.9 cm³/rev displacement and a maximum continuous pressure of 210 bar (up to 250 bar peak), it stands out for its low pulsation and ability to operate in both directions of rotation. The pinion-shaft technology enables direction changes in the millisecond range.
