Moog Electrohydrostatic Pump Unit and Electrohydrostatic Actuation System
Moog Electrohydrostatic Pump Units (EPU) are emerging as a viable option for industrial machine builders as the design combines the best of both electro-mechanical and electro-hydraulic technologies. The EPU is a highly integrated, compact alternative to traditional hydraulic solutions. Automation engineers moving toward electro-mechanical actuation in pursuit of energy efficiency and environmental cleanliness, will find an EPU an attractive option for high force density actuators.
This catalog describes the Electrohydrostatic Pump Unit used in such electro-hydrostatic actuation systems, like the Moog EAS. The EPU is able to operate in 2 or 4 quadrant operations and has a mechanical interface, which allows to connect it directly to hydraulic cylinders or manifolds.
The Moog EAS is a modular actuation system comprised of a Electrohydrostatic Pump Unit (EPU), Servo Drive (MSD) and manifold. Adding a cylinder as part of the system is also a common option. Moog’s global engineering teams help customers select and integrate these building blocks into a highly customized system that serves unique application requirements across diverse industries

Installation note:
To avoid pump damages the housing pressure pL must not exceed the pressure in the low pressure line (pA or pB) by more than 1bar.
Design the drain line with lowest possible pressure losses.
