Moog launches electrohydro-static pump unit
July 2017
Motion Control & Drives
Moog has launched a new-generation electrohydrostatic pump unit (EPU) that will help machine builders and end-users derive the combined benefits of both hydraulic and electric actuation. The Moog 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.
“Our EPU is the most compact product in the market,” said Moog innovation manager, Dr Helbig. “It is ideal for companies that want a standard, out-of-the-box product that can be easily integrated into their hydrostatic transmission or new machine designs. It has a mounting pattern which allows direct mounting onto a cylinder via a manifold. This reduces piping costs. Installation times can be shortened and maintenance work can be considerably simplified.”
The new electrohydrostatic pump unit can be used for a wide range of applications, such as metal-forming, heavy industry, injection moulding and die-casting, gas and steam turbines and wind turbine pitch control. “Even short periods of machine downtime can translate into significant efficiency losses and cost,” said marketing manager, Robert Luong. “Our new electrohydrostatic pump unit is ideal for high force machines and systems that need to be fail-safe. Most of our customers will reduce their total cost of ownership due to the lower maintenance required and reduced need for customisation.”
The electrohydrostatic pump unit is available either as a standalone 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. “Companies that need not just a compact pump unit but also the corresponding system can now get everything from one supplier,” said Luong. “And of course everything is backed by Moog’s long experience and expertise in manufacturing motors and pumps, as well as our technical support.”
