Wepuko PAHNKE’s PMSD drive

PMSD stands for PAHNKE Modified Sinusoidal Direct drive. This is a design developed by PAHNKE Engineering in accordance with plans from Hans-Joachim Pahnke.

This drive does not require any valves for the control of the press movement. The RX-series high-pressure pumps are able to determine the force, speed and direction in a fast, smooth (shock free) and efficient manner. These pumps are extremely reliable and will perform flawlessly for at least 30,000 hours. Some of our customers have logged more than 50,000 hours of operation without needing any repairs!

Energy savings of approximately 25% vs. any other drive system of comparable drive system is achieved as a result of this brilliant design. All of our new presses are equipped with hydraulic drives that are designed and manufactured in accordance with the PMSD principle.
