Oudshoorn hydraulics is distributor of Bucher hydraulics internal gear pumps

The QX pumps are the 5th generation Bucher internal gear pumps that have proven themselves in the last 30 years. The simple design guarantees a long life span without needing extensive maintenance. Pumps connected in series and multiple pumps are available worldwide in more than 1000 different versions.

Advantages :

  • High working
  • Low noise level
  • Long life span
  • Negligible flow and pressure peaks

Double pumps

QX double pumps are made of two single pumps mounted on a common shaft.

These pumps operate independently from each other but share a common suction connection in the center of the pump. The largest pump of the combination is located at the end of the axle (on the drive side). When the pumps are of equal size the pump with the largest stroke volume is located at the drive side.
