QXP42-032R Single Internal Gear Pump 32.3 cm³/rev 210 bar

Designed for hydraulic circuits requiring high flow rates with unconventional fluids, the QXP42-032R is an internal gear pump from the Bucher Hydraulics QXP series, frame size 4, pressure range 2. With an effective displacement of 32.3 cm³/rev and a maximum continuous pressure of 210 bar, it delivers significant flow rates while maintaining extremely low pulsation levels, a hallmark of Bucher's gear profile design.
