Electrohydrostatic Pump Systems

The Electrohydrostatic Pump System (EPS) consists of an Electrohydrostatic Pump Unit (EPU) and a standardized manifold with hydraulic accumulator. It is offered as a complete system without an actuator and can be easily integrated into machine concepts, whether retrofit or new developments.

In terms of scope and flexibility, the EPS positions itself between Moog’s EPU and Electrohydrostatic Actuation Systems (EAS), giving customers the freedom to design the system according to their needs. Different motor-pump units and power classes are offered, as well as different cooling concepts and additional features such as functional safety.

Optimal design of the system peripherals can reduce the size and power of electronic components thus the connected load. In combination with an intelligent energy management system, this leads to significant savings in total energy consumption in the medium to long term. Moog offers a wide range of suitable power electronics and software solutions to exploit this potential.

The standardized system is easy to maintain, highly adaptable and allows the use of existing customer components such as hydraulic cylinders. The standardized connections and components facilitate easy integration and scaling, reducing development, design and assembly times for faster time-to-market.

Benefits:

• Flexibility in machine integration
• High force capability and power density
• High energy efficiency
•  Greater environmental friendliness by minimizing oil consumption and noise emissions
• Low total cost of ownership (TCO) and shorter time to market.
• Decentralized drive system with small footprint eliminates need for large hydraulic power unit (HPU) and reduces piping and installation costs
• High system availability
• Energy managament system available
