Pump system saves energy by 70%

Written by: Tom Austin-Morgan | Published:

Power management company, Eaton has produced a variable speed drive pump system that it claims is capable of providing machine and system builders with energy savings of up to 70%.

The fully integrated electro-hydraulic system represents a flexible solution for machine automation and control and is comprised of high efficiency variable speed electric motor drives that provide for reduced hydraulic power unit operating costs of up to 40%.

The integration of vane and piston pump options can enable machine builders to further reduce operating cost by up to 20%. In addition, the system provides for extended machine life by lowering heat generation and improves operator safety and comfort by reducing pump noise levels.

Combining the power density of Eaton's pump systems with the smart control functionality of variable frequency drives, the system can achieve power-on-demand in a more energy efficient way than a conventional constant speed pump system.

In combination with Eaton's automation offering including HMI/PLCs and the SmartWire-DT communication and wiring technology, setting up the monitoring and control for force, direction and speed of the proportional pressure relief valve system is said to be simplified.
