Electrohydrostatic pump unit

Second Quarter 2020 Electrical switching & drive systems & components

MOOG has launched a new generation electrohydrostatic pump Unit (EPU) that helps machine builders and end-users derive the combined benefits of both hydraulic and electric actuation. The EPU is at the heart of electrohydrostatic actuation and helps enable the deployment of a decentralised drive system. This eliminates the need for a hydraulic power unit and complex piping, thereby reducing the overall machine footprint. The compact product design features a unique interface that enables direct mounting onto a cylinder, thereby minimising the requirement of additional space on each axis.

The EPU has been developed to meet the needs of OEMs, system integrators and end-users, who increasingly seek cleaner energy-efficient products without compromising on the requirement for high forces. It is designed for easy installation and commissioning and can be mounted directly onto a cylinder, thereby reducing the number of components required. The self-contained units have a reduced chance of leakage and breakdown and help lower ongoing maintenance costs and the total cost of ownership.

The electrohydrostatic pump unit is available either as a stand-alone product or as an entire system, called the Electro-hydrostatic Actuation System (EAS). The EAS combines the electrohydrostatic pump unit and any optional parts a customer might need, such as drives, controllers, manifolds, or cylinders. All components are MOOG products that meet the highest standards of reliability and quality.
