Accommodating your needs

PD(S)-series: accommodating your needs

In the PD(S) series we offer two types of pumps: the PD and PDS radial piston pump. The difference is in the maximum operating pressure of both pumps. The PD pump can generate a maximum pressure of up to 700 bar, while the PDS pump can deliver up to 1.000 bar! Besides, we offer this type of pump directly connected to a gear pump as well.


  • 500 Bar / 700 Bar / 1 000 Bar
  • 0,22 to 3,22 cm³/rev
  • High volumetric efficiency (up to 98%)
  • Wide speed range (100 > 3 000 rev/min)
  • Combination with gear pump possible
  • 1 to 2 Pressure outputs possible (depending on n° pistons)
  • Low pulsation, low noise level
  • Self-priming and venting
  • Offshore versions available (Marine version)


  • Size 2
  • Light weight compact version
