P(S)-series: robust and durable
Wimmer radial piston pumps are extremely robust radial devices with highest reliability, even under roughest conditions. Our P(S) series consists of two types of pumps. The P series hydraulic piston pumps can generate a maximum pressure of up to 700 bar, while the PS pumps have a maximum operating pressure of up to 1.000 bar. In combination with a gear pump they are perfectly suitable for different kinds of applications.
