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.
