The Moog Electrohydrostatic Pump Unit (EPU / EPU-G) is at the heart of electrohydrostatic actuation systems enabling the deployment of a decentralized drive system. The Moog Electrohydrostatic Pump Unit (EPU / EPU-G) is at the heart of electrohydrostatic actuation systems enabling the deployment of a decentralized drive system. This eliminates the need for a hydraulic power unit and complex piping and helps reducing the overall machine footprint. The compact product design features a unique interface that enables direct mounting on to a cylinder or manifold thereby minimizing the requirement of additional space on each axis. Addressing customer needs for convenience, modularity, electrification, energy efficiency, robustness, serviceability and sustainability, the compact design and reduced complexity make it easy to handle and integrate without requiring extensive hydraulic expertise. The EPU-G (sizes 13 and 20) utilizes an internal gear pump to generate flow. The EPU (sizes 19, 32, 80, 140 and 250) uses a radial piston pump available in two versions: Fixed or dual displacement. • High energy efficiency. • Reduces oil volume by up to 90%, supporting sustainable and clean operations, reducing maintenance and operating costs and the risk of fire. • High-force capability provides a viable alternative to EH actuation. • Unique manifold interface enables direct mounting reducing piping and maintenance efforts and machine footprint. • Self-contained and compact product design reduces space requirements for the machine. • 4-quadrant operation.
